Use 1/2 ounce to 3/4 ounce glass cloth. You can apply it with slow drying epoxy, laminating resin or clear polyurethane paint.

The underlying surface needs to be as perfect as possible. Sand it, sand it some more. Look at it under good light. Yep, it still needs more sanding.

Now sand it again.

Vacuum it and get ready to glass (after sanding it again).

Start from the bottom. Use SHARP scissors to cut the cloth. You can also put the cloth between two sheets of newspaper to help prevent fraying.

You DO NOT need to use spray glue, CA or any of the other stuff that people suggest to hold the cloth in place. It's more work. Lay the cloth over the surface and pour a thin bead of resin down the center.

Use a pieve of 1/8" balsa sanded smooth with rounded corners (to prevent snagging) and scrape the resin out from center. Keep scraping. Add more if necessary, but you want to remove as much of it as possible. The resin is only there to hold the cloth down - not to fill the weave.

After it is cured, give it a very light sanding to remove the rough spots and feather the edges. Then do the sides the same way. Lastly do the top.

I prefer to use laminating resin because it is the perfect consistency and it dries harder than regular epoxy which means it sands better.

I've never used polyurethane, but some guys are using it and like it. Apparently the technique is the same.

If you use regular SLOW DRYING epoxy, DO NOT thin it with anything. Some people do, but there are plenty of stories about the stuff not curing properly and it's not necessary to thin epoxy ever. Just warm it up a little in a pan of warm water to get it thin. The working time will go down though because heat speeds the chemical reaction.

Overall, fiberglassing will give you a great long-lasting and durable finish and it's not hard to do. Once you start you'll realize it's pretty simple. Just make sure you work over newspaper and have all your stuff ready before you start. Make sure your work area isn't cluttered.
