dont bother with gel coat. Lots of sanding, and take it to an autobody shop for a good automotive paintjob.

Gelcoat was the thing to do about 12 years ago when fiberglassing was pretty new. Now, you would sand down the fleece with 40 grit to get it decently smooth, then apply some filler to fill in the low spots, sand with 100 grit, primer, then 220 grit, then primer again and send off to body shop [img]smile.gif[/img]

you can make your own bondo milkshake if you want as well. Depends on your skill level. Simply mix resin and bondo together, and off you go!!
