Why is there never enough time to do it right the first time, but always enough to do it right the second time.

Thanks Dave,
I'll have to check it out.
I have some Blue gelcoat that needs to be brought back to it's original brilliance and some blisters to take care of on her bottom this spring.

When I bought our 1985 2850 in 2000 it had maybe 100 blisters dime size or a bit bigger.
I found a simple fix for it.
I took a hammer and screwdriver, placed the screwdriver on the blister and hit it. Ping, it popped the gelcoat right off.
The boat had been sitting for a year or more in a storage barn and the blisters were dry. That is most important. If not water is a great resin release and it will not bond.
I filled the voids with simple fiberglass resin. I used a body puddy plastic applicator. It took a few applications because I was working upside down.
I then sanded them smooth with an air sander like body shops use. I did not get into the gelcoat much if at all.
As I had no intentions of bottom painting it I sprayed it with automotive lacquer using a 1980 GM automotive white which is an almost perfect match for that year (and other) gelcoat.
I know automotive lacquer isn't available now but if you bottom paint it will protect it just the same.
I didn't paint the complete bottom, just spotted it where I repaired the blister.
I sold that boat last year. I never bottom painted it and you could not tell where it was repaired. Not one blister repair failed and no further blisters started.
It was a simple repair that took very little time and it worked.
Btw, there are still places in the states you can buy automotive lacquer. Just Google it. You can paint it over gelcoat without a primer. Its hard and thin so there is no buildup.
here is one place you can get it. www.tcpglobal.com/restorationshop/rspacl..._f0K4CFY1R7AodhXIUAw

Thanks for the tip about the blisters I iwll give it a try.
I will be doing the bottom coat though so I will be sanding, but I was really more concerned with fixing the blisters.
I'll keep everyone posted once I start the project.

Just be sure its bone dry.
Don't cheat on this.
Might be good to pop them now if you can keep the snow and moisture from getting
Mine were dry from the getgo. Hope you are as lucky.
