wet sanding

[bryanrutledge]

my bass boat was very dull so i sanded it down and put on two coats of spar urethane. can anybody tell me how long i should wait before wet sanding. i plan on putting three more coats on wet sanding between each coat with 600 grit and then polishing with a auto polish on final coat.

thanks in advance
Bryan

Re: wet sanding

Is this a fiberglass boat? You put spar urethane on it? What brand? 600 grit might be a bit aggressive.

Re: wet sanding

it is a fiberglass boat. it is hellsman brand spar. ive read somewhere that this was a good alternative to re painting boat.

Well, I would not have used it. I know it says it can be use on fiberglass etc.. but not my choice. Is this a metalflake boat?

If it was dull then you should have just sanded it with 800# lightly then 1000 grit and buffed it out with wax or rubbing compound.

Re: wet sanding

it is a metal flake boat and it was so bad that you could feel the flake and it was fall ing off. i already put three coats on it and now it is pretty slick. i was going to wet snd the n put final coat on and then buff. it probaly wasnt the smartest idea but it was what i come up with. and looks better than before. hope to get about two years out of it. thanks for your comments

Re: wet sanding

It will prolly last a couple yrs. Final wet sand with 1000 grit and buff with compound

Re: wet sanding

In my opinion urethane will not bond well to fibergas and adding sun won't help either! Let us know how this works out over time.

I would regularly spritz/rub her down with something with plenty of UV protectant in it. Aerospace303 or Marine Wax
