Is 400 grit to fine?

On my can of prekote it reads 220 grit or wet sand with 400. I like the feel of 400 but does it give enought tooth for the paint? I used 400 on my last boat for varinsh and haven't had any problem.

In my limited experience 400 grit wetsand paper is not to fine and will give you adequate tooth.   It's what the autobody pros use.

I'm a woodworker/furniture maker. Over the last few years, I have been sanding to 4000 (four thousand) grit followed by 2 levels of posih + wax. You can't beleive how much improvement you can feel between each coat. It does make a difference. OTOH, I don't put epoxy on the final product. NOt sure what the final finish would be if you went to 4K grit but be interesting to try it.

Wet sand with 400 grit. It produces an excellent surface for paint or varnish and no dust. Dave
