I put the second coat of epoxy on and here is some info that might be useful.
Two coats and I have reached 10 mils of thickness. The can says you want to be 12 mils thick for the barrier coat to do its job.
It takes 2 quarts to do the bottom of the boat so a gallon will do two coats.
I am going to put the third coat on today and will see where that puts me. I was planing on at least 4 coats.
Oh and did I say I hate painting !!!!

Wow! You really saved a lot of money doing it yourself, even if it was a pain. I redid the bottom paint on the 25 we used to have. Wasn't as mechanically inclined as you so I took her to the local marina yard and paid to have her put up on blocks, but I cleaned and repainted. It lasted a good long while.
It was a pain for me, too, but a money saver, for sure!

Yeah, you don't know how bad I'd like to have a nice warm shop big enough for the boat!
Maybe once the wife retires and we move somewhere that doesn't hurt our face to go outside! (-14 forecast for tonight...) But I keep dreaming! 8) Colby

All of the bottom paint is finished. Started making the new wheels to put the trailer under the boat again. It took about a half a day to get trailer out from under the boat with flat tires ( they don't roll very well when all 4 are flat) had to winch it out from under the boat. New wheels are 1/2" baltic birch plywood.

Are those load range c or d? 
I'd be a little nervous just using 1/2". But has to roll better than on flat tires! Colby

Load Range B for Birch. :lol:

Nicely done. I'm still impressed that only two 1/2" "wheels" didn't splinter under the strain. It'll be interesting to see how your paint holds up where the bunk boards go. Mine is already starting to wear off from loading the boat after many launches. More so where the bow runs up on the target boards. Colby

I used the Pettit Hydrocoat Ablative bottom paint. Cleaned the bottom off of much of the old stuff that wasn't put on very well before I bought the boat, and then painted over that. I think when I redo it, I may take it down to the fiberglass and start from there with an epoxy coat. I can't tell if there was any primer coat originally or not. Didn't seem like it when I worked on cleaning the other stuff off. Next time I may just take it to a boat yard. Otherwise I may use the sandblaster rather than the pressure washer. Then again, most my boating is fresh water, so other than for cosmetics while on the trailer, I probably don't really need to worry too much about it.

Water based. But just the regular stuff, not the eco.

Colby, please do not go below the gel coat. The reason is if you get into the glass, then individual fibers are exposed. Then if some abrasions occurs, there will be wicking of moisture. This is the same reason I tell people not to sand blast the bottom. Using dry ice or some less aggressive media can be done, just to remove the bottom paint, and not the gel coat.
