Glad I could inspire you! So here are the deets
The age of the helmet probably won't affect it. Just make sure it's sanded down (I used 200 grit) and primed well. I did 2(?) light coats of primer I got at Lowes. For materials I used Humbrol Enamel Paints that I bought here. I strongly recommend you get the 50ml paints... you're going to screw up a bunch. Also get high gloss, and don't get metallic paints, they don't swirl well. I didn't use a dip film like you would see at a shop, I did the swirl myself. This Youtube Walkthrough was my bible, though I did watch multiple other videos. There a few that are done on guitar bodies that are helpful, but ignore the ones that use spray paint. I used plastic pipettes here for application onto the water.
For the water, I used a 15 gallon container that was sitting in my basement. 13 gallons of water in it lined with a trash bag for cleanup, and then I brought the last gallon to a near boil and added 20 Mule Team Borax at 1.5 tablespoon/gallon, though i was very generous with the measurement. Dump that into water that is at 78º F which you can get to by using a fish tank heater and mix. I used an electronic meat thermometer to confirm temp, because the heater I bought was a piece of garbage and wasn't close (learned this the hard way).

For swirling, follow the youtube tips. Drip drip drip one color then drip drip drip another. Repeat. I used a nail for the swirling.

For dipping I used a long clamp I had for another project and dipped chin to top. I started at about a 60º angle, going down AND back and forth as I went. Since the top of the helmet is so large, I turned it to like a 20º angle when I got there, continuing the lateral movement. Once it's dipped, use your gloved hand to push the remaining floating paint to the side and pull the helmet out and rest it somewhere from the inside. I screwed a 2x4 piece to a small piece of plywood and made a stand.

Anything else you wanna know? I'm happy to help.

Edit: Don't get discouraged when it WONT FUCKING WORK YOU FUCKING PIECE OF SHIT! Just wipe it up with a paper towel, skim it with a colander, and start again. You'll know when it's right, you're gonna feel it.

Yes clean around wound. The flap has to go. It’s going to bleed when it’s clipped but that’s good cause you’re getting healthy tissue with blood vessels.

Think that covers basics. Alcohol, self adhesive wrap, salt for saline, styptic powder, gauze, theracyn (antibiotic for superficial injuries), silver nitrate (only use with wooden applicators- strong cauterizing agent), pipette, electrolyte ( 1/16 tsp to 8 oz water. If chick is ill add honey for quick energy then mix solution with food to make mash), bottles, betadine ( I cut to 50% strength with saline), and gorilla glue with brush and dispenser. Oh and gloves and shaver:)

Ok, will try again - i am knocking things out with a pipette (similar to this: https://www.amazon.com/Teenitor-Disposable-Pipettes-Transfer-Essential/dp/B071JXVGNK ) but it keeps coming back somehow :(
