Baking soda + water are great for clean dirty car battery terminals.

Disconnect the negative battery cable, then disconnect the positive cable.

Make a slightly watery mixture of baking soda and water (filtered or distilled is recommend), and carefully pour the mixture onto the battery terminals; Be careful not to let the water touch both terminals.

Using an old toothbrush or wire brush, scrub the corrosion off the terminals, then rinse with filtered or distilled water.

With your terminals nice and clean, repeat the process on your battery cable connectors (it might be easier to soak the connectors in a baking soda solution instead of trying to pour it).

apply either battery terminal protector, Dielectric Grease, or a thin layer of [protroleum jelly] (http://www.amazon.com/Vaseline-100%25-Petroleum-Jelly-Ounce/dp/B007E62538/ref=sr_1_cc_2?s=aps&ie=UTF8&qid=1374477009&sr=1-2-catcorr&keywords=petroleum+jelly) to the terminals of the battery.

Reconnect your positive terminal, then reconnect your negative terminal and you're all set!

I bought a new 50th Anniversary Camaro, which has a Matte section on the hood. I've been searching and reading the wiki, and just want to verify or get better recommendations than what I think I've found.

I first need to wash the car with a matte wash, so I don't get any glossifiers or waxes on the matte section. I found Chemical Guys CWS_995_16 Meticulous Matte Auto Wash, but wasn't sure if there were other recommendations.
After that, I should use a matte sealant like Chemical Guys WAC_203_16 Blue JetSeal Matte Sealant and Paint Protectant.
Then for touch-ups use Chemical Guys SPI_995_16 Meticulous Matte Detailer and Spray Sealant.
With that done, I should tape off the matte section, and care for the rest of the car with regular wax, clay, and sealant as covered in various threads and the wiki here. For the tape, I see some recommend 3M 233+ painter's tape, while others say CarPro Masking Tape. Is there a significant difference between them?

Does that sound correct?

Thanks for reply Laguna.

Here's picture of my hood and waterspots (can't really see it but its there) on my sidedoors.

What do you think about compounding?
I checked out the other products while I don't doubt at its effectiveness they seem more expensive..so for my Civic I don't mind sticking to Meguiar's or Mothers.

If compounding is necessary do you think these steps are okay?

  1. Wash Car completely
  2. Clay bar with Mothers clay system
  3. Ultimate Compound by Meguiars (So I can skip ScratchX/SwirlX) since I want to do my whole car.
  4. Ultimate Polish
  5. Meguiar's NXT 2.0 Wax (OR this one from Chemical Guys? http://www.amazon.com/Chemical-Guys-WAC_113_16-Factory-Sealant/dp/B001THP2I8) I heard Sealant is better than Wax...for outdoor cars since this is my daily driver and is parked outside.

    Any Thoughts?

    Btw MF towels aren't good for the paint?! That's news to me...what do I use to wipe the car then?

    Thanks again dude!

Silicone won't last up there, but can be a temporary fix. Keep in mind you will have to remove it and clean the area quite well when you do the permanent fix. Dicor Self Leveling Lap Sealant is what you need. I provided the link so you could see the label. Camping World will carry it for sure, if you have one near you. I am not sure if Lowe's or Home Depot carry it. This is THE solution you need.

u/CaptainPreposterous · 3 pointsr/vandwellers

Always loved that body style. Definitely a head turner. I used Dicor self-leveling Lap Sealant on my Transits Maxair fan, good stuff.

u/axemanjohn · 2 pointsr/bikebuilders

I'd put my money and effort into the tank you got, It it isn't falling apart, it's restorable.

Get a quart of metal etch https://www.amazon.com/POR-15-40204-Metal-Prep-quart/dp/B00J5940JE?source=ps-sl-shoppingads-lpcontext&psc=1 , a quart of gas tank sealer https://www.amazon.com/POR-15-49216-U-S-Standard-Sealer/dp/B00B3HXCZ4/ref=asc_df_B00B3HXCZ4/?tag=hyprod-20&linkCode=df0&hvadid=312128189269&hvpos=1o4&hvnetw=g&hvrand=9870445733732195706&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9021744&hvtargid=pla-522130837870&psc=1, and a gallon of diesel fuel, total around $40.

Remove the tank and remove all fittings. Get some corks or plugs for the openings. Put in 1 cup of diesel and a handful of nuts, small screws, and similar steel parts, cork up the tank and shake it up, agitating it so the hardware is scraping against the rusted areas. Drain the diesel and keep it for parts washing. Continue to use the nuts and screws in the tank. Some folks say gravel makes a good scrubbing media, but I think it's more inclined to break into particles than metal.

Put in the 1/2 cup of metal etch with as much water as the label recommends and with the same hardware shake it up, turn it over, shake some more. the idea is to get removal of the flake rust and penetration of the pits. The metal etch will convert the accessible iron oxide to iron phosphate which is more stable and less reactive. The chemical needs time to work, and soft red rust needs to be mechanically removed.

Rinse with diesel or hot water and repeat. When the red metal looks gray or black it's done. Get off any film or crust as best you can. After the last rinse, make sure all the little steel hardware is out, then oven or otherwise dry extremely well. Don't neglect the tank during the process by leaving it for days with acid or water but keep it moving along.

Dont risk riding with a makeshift rig. A leaking tank over a hot engine can make a heck of a fire.

u/dont_get_pissy · 2 pointsr/whatisthisthing

Use some baking soda and water (spoonful to a cup), let it work (3-5min), then brush with a wire brush. Then remove the terminal and repeat on the terminal and the battery post. Grab some battery terminal protecter and give it a nice coat. Following these steps takes a little more time, but is the most thorough and longest lasting method I've come across. Cleaning the outer surface before removing helps your wrench get a better bite when removing pesky terminals.

u/imprl59 · 5 pointsr/MechanicAdvice

Clean it up good then you can use anti-corrosion washers or [anti-corrosion spray](https://www.amazon.com/Permatex-80370-Battery-Protector-Aerosol/dp/B000BOKML2/ref=sr_1_2? s=automotive&ie=UTF8&qid=1496404545&sr=1-2&keywords=anti+corrosion+spray) or just coat them in a heavy grease after you retighten.

The corrosion is caused by the dissimilar metals and perhaps a bit by the hydrogen gas generated when charging the battery.

u/yourbadinfluence · 5 pointsr/MechanicAdvice

You can try to clean it off with a wire brush and white vinegar. It looks pretty bad though, I'd make a trip to the dealer and get a new part. Then when you install it spray some of corrosion preventative on the exposed metal. Here is a link to one product but I'm sure your local auto parts store has it or something similar.
Permatex 80370 Battery Protector and Sealer, 5 oz. net Aerosol Can https://www.amazon.com/dp/B000BOKML2/ref=cm_sw_r_cp_apa_owJ.yb6PW3WWM

Butyl tape or Dicor underneath. Either the leveling or the Gravity-Defying version.

Then the fan.

Then Dicor Self-Leveling Lap Sealant around the edge - it oozes into the cracks and crevices. I used three layers, the first a small bead that I watched slide right under the seam! Then a couple big beads to spread and coat the area.

And I followed the Dicor with EternaBond over top of the seam.

As seen here.

u/dk00111 · 1 pointr/Volkswagen

Nothing looks worse than a car with great paint but faded plastic trim. Don't forget the trim protectant.

u/combatchuck · 3 pointsr/MechanicAdvice

I've never understood why people think that pouring Coke, which has phosphoric acid, is supposed to clean up battery corrosion caused by sulfuric acid. Scrape off the corrosion, dump a bunch of baking soda on there, let it sit until it cakes, and scrape that off. Wire brush clean. Keep your terminals as sealed and dry as you can. They make spray to keep the terminals protected. It works wonders.

u/walkersm · 1 pointr/MechanicAdvice

Probably this stuff. Most of the reviews say it dries purple.:

u/secessus · 1 pointr/vandwellers

Butyl underneath then dicor around the edges is the traditional approach.

If you use painter's tape as a border (maybe .75" away from the edges) you can remove the tape before the sealant sets and avoid the melted wedding cake effect.

u/bkrassn · 1 pointr/vandwellers

Why not use dicor lap sealent?
https://www.amazon.com/gp/product/B000BRF7QE/

This is what I used on my maxxfan, been through plenty of storms during the last 6 months. No leak from the fan.

u/in_air · 1 pointr/AutoDetailing

Process:

  1. There was a lot of dirt and grime. So sprayed APC 4:1 and agitated the dirt using a brush similar to Boar's hair brush and wiped using a MF towel. One part at a time.
  2. Used ONR 256:1 to rinse each part as APC was having a sticky effect on the parts. Wiped using MF towel. Used different brushes to reach the areas not reachable with hands.
  3. Used Sonax Plastic Restorer to dress the plastic and rubber parts and wiped using MF towel.

    P.S Despite watching different videos and getting assurances, couldn't muster up the courage to spray water on engine using pressure washer.

I've been detailing my own cars for a few years now. I just purchased a used motorcycle and wanted to give it a good cleaning.

However, the paint on the bike is a rough texture and I suspect its a matte finish. It doesnt feel like something I should be applying wax to. Any recommendations for protectants for matte paint?

I found this from Chemical Guys, but its $40 a bottle and gets horrible reviews. https://www.amazon.com/dp/B00H45R002/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=3T6KJGTAQVBRQ&coliid=I19YLOQVDHSJ4&psc=1

additionally, what else should i avoid with this type of finish? Can I still wash and clay as I would normally?
