Proper sequence for painting

[Noklin]

I covering my CS20 with cloth and three coats of epoxy. I then sanded most of the epoxy off to get a smooth finish. I started with 36 grit, followed by 80 grit and finished with 120 grit. What is the proper sequence of painting from this point?

Do I now paint over the sanded finish since it would provide plenty of

I don't know that you need any more epoxy, but I can't say really one way or the other with out seeing it.  If you have exposed any cloth you should probably do another coat.  If you do another coat you should at least light sand again before paint.  80 or 120 grit as needed, it really isn't that critical.  If you are going for a really shiny finish much finer paper should be used with each coat of finish paint.  Unless the products you are using can be hot coated (recoated before full cure) you should sand between all coats, paint, epoxy, what ever.

Couple of points I would like to add to what Dave already mentioned. You really want to make sure none of your glass is exposed. That stuff will absorb moisture like crazy. One alternative to more epoxy would be to go with epoxy primer such as Devran 201. I use it and like it. Cures up almost as hard as regular epoxy. Use with any paint from oil to polyurethane. The only drawback -in my opinion - it takes a while to cure hard enough not to gum up the sand paper. If you top coat with polyurethane you can lay a coat on 4 hrs into primer cure. That rarely happens to me as I tend towards sloppiness  and have to do lots of sanding between coats. The cost is reasonable $35 -40 a gallon I believe. PeterP
