Looks cool but the things that stand out to me are, 1. The review that says it's single use rolls 2. The amount on the rolls. The 1" tape gets you ~1/3rd of a square foot of coverage with no overlap for $6 ($21.6/sqft), the 2" tape gets you ~2/3rd sq ft for $8 ($11.5/sqft), and the 4" tape gets you 1.7 sq ft of coverage ($6/sqft). Seems pricey, even more so if I have to toss out any partially used rolls. I might still try it because new materials intrigue me but it seems about as good as laying fiberglass over a plaster guaze cast or just wrapping in fiberglass and resin. Surface finish will be a factor because hours saved sanding are valuable hours indeed.
EDIT: math
EDIT2: For comparison, the fiberglass kit gets 8 sqft of cloth and 32oz of resin. I'd expect it to get me 4-8 coats on 8 sqft (never had a project that used the whole 8 sqft of cloth at once but I'm estimating about 4-6 oz of resin per coat and that 1st one always takes a bit more). Throw in a 50 cent chip brush for each of 4 coats and the price is about $25 or $3.1/sqft with the added bonus of being able to save the resin left over for your next project.
If you want to do it right, you're going to need some fiberglass sheeting and some resin. For the first one, you could use some surfboard repair resin like this
I think the second one is too large just for that. This looks like a good, cheap kit that would repair both of them.
Just remember, if you haven't worked with this kind of stuff before, the cleaner you apply it, the less you'll have to sand later!
