Awlgrip or other?

I have an old salvage 13 that's been reworked many times by prior owner(s). There is an extra layer of non-woven fiberglass below the waterline that someone applied. There are long stress cracks in the gelcoat on the outside freeboard which have been painted over (several times). If it were an old horse I'd take it out back and shoot it but because it's a old Whaler (a noble creature, indeed) it must be restored.
The process I think it needs is:
Looking for comments on products and my "process" or any step of the process.
Expense of materials --max about $200 if I can get away with it. Thanks.

Spraying two part paints that include isocyanates (linear poly, awlgrip, etc.) is serious business, a supplied air respirator ($500+) is considered by many to be a necessity. Problems associated with exposure to this type of chemical are death by chemical pnumonia, liver failure or liver cancer. Rolling, then tipping with a form brush is safer and the result can be OK. In any case, I think the price for a "mixed quart" of awlgrip, including hardener and reducer would be above your budget of $200.
In any case, I would consider acrylic urethane rather than linear polyurethane. I've used these paints many times with OK results, they can be wet sanded and buffed after application, a real plus if working outside a spray booth.

SteveC: That is very good advice regarding Awl-grip. It is very nasty stuff.
As you indicate, linear polyurethane is not meant to be wet sanded or even polished out. I have heard that people do it with success anyway. Wonder if anyone has had success in that regard.
The advice to use something like interlux / interthane is pretty sound.
