[quote=tominpa]If you have some patches, it is likely you will need to fair the repairs to be smooth enough for final finish. My favorite material for this is West System Epoxy mixed with 410 Microlite filler / microballons. This material lets you form a thickened epoxy that shapes easily and has no air pockets, pits or similar problems. I use a 12-inch long sanding block to have good control over the fairing of curved and straight repairs. It's much easier using a long narrow sanding block. You can spend a lot of money, or get a cheap one from Harbor Freight that works great. This one works great for me.

For final finishing, I used Interlux Primekote epoxy primer and Perfection top coat.

Other members have use AlexSeal 2-part paints. One advantage of paint is that repairs can be matched. For example, last summer my boat got holed during a storm. You can see the repairs in the following images resulted in a perfect invisible match. The filler shown is West 407 fumed silica over 7-layers of epoxy saturated woven glass. This was finished with 410 Microlite, faired and painted with Primekote and Perfection Arctic White.
