I suggest looking into applying the fiberglass using the water base polyurethane technique. While this only provides about 60% of the strength of a resin fiberglassing, it is about 1/2 of the weight of a resin job.

As for painting, I suggest using latex paint. You can get an EXACT color match for about $10 per quart. Latex does need to "cure" about 7 - 10 days, then it can be be clear coated with water base poly for fuel proofing.

Here is a link to using latex for painting.

If you are interested in using the latex and/or glassing with water base polyurethane and need/want additional information, please feel free to contact me.
