Make easy, permanent repairs on hairline cracks, small scratches, and chips in gelcoat without sanding or using catalyst! Clear patch is ideal for surface scratch repairs of metal flake finish. 1/2 fl.oz. tube.
I had 3 nice sized gashes in front bow of my new boat. It knocked the gel coat off but the fiberglass and glue underneath were luckily ok. The tricky part was the chips were under the bow of the boat so the good news was the area would not see much water but it was hard to get to since I had to apply from underneath. I took the advice of an early review and put it on layer by layer. I put on thin layers and did not worry about filling in the entire gash at once and put it on in layers. after 3 layers it turned out pretty good and after wet sanding, it was almost perfect.
I had one gash the area of a half dollar and 2 chips the size of a coin slot in a coke machine. I was surprised how well the big gash filled in and was pleased how easy it was. I would suggest a fine grit sandpaper. the finer the grip and the more time you spend on sanding and buffing the better.
it has the consistency of glue so was you are putting it on it adheres to pretty well so worry about spreading it completely to all the nooks and crannies first and then build off it.
Works best on hairline cracks/tiny chips. Would not recommend on big scratches/gouges as you have to let it dry completely or risk pulling it out when smoothing/blending. Temperature has big affect if not in recommended range.
I might as well just get play dough and shove it into the chip. This stuff is soft even when left to dry for days. This is NOT a PERMANENT fix as advertised. If you wanted to hide an unsightly gash in your boat for a couple days and don't have time to sand, this would be okay but it is not nearly as durable as the gel coat.
Used this to repair a REALLY big chunk that had been taken off by the previous owner when he dropped and anchor on the deck of a 21ft center console. The chunk was about the size of a 1/2 dollar and down to the base material.
I had tried to use this as directed but scraping it proved impossible, it would just pull most of the material right out. Having a background in automotive body work, I decided to try to add a small amount, let it cure (about a day) and add more, let it cure, etc. and build up the repair area. Worked like a charm. Built it up, took some 400 grit, sanded it down, took some 1000 grit, leveled it out, took some 2000 grit, started to polish it, some automotive buffing compound and a polish later, it looks pretty decent.
5 stars for decent price. 1 star for making me figure out the best way to use it and not having good directions on the package.
