Re: painting a fiberglass fish & ski
Have you painted before?
It is one of those things that looks really easy but isn't.
I did mine on the trailer this year, jacked it up and put 3 wood blocks under it then removed the bunks, the bottom was still a pain but it worked pretty well.
Sherwin Williams or Napa have a good selection of auto paints in single stage but have your wallet ready, depending on color it can get a little pricey and you will probably need a gallon with reducer and hardener, about $200 total, i used base/clear on mine, alittle more forgiving than single stage.
As Bob said a good paint job is all in the prep, I spent probably 30 hours sanding and 2-3 hours painting then another 6-8 sanding(2000 grit) and buffing but it look sweet now.
The difference betwen a $300 paint job and a $3000 job is about 100 hours everything else is the same.
Here is a link to mine, maybe you can get some ideas from what I did, it even involves a murder, well a murder trial anyhow, not mine.
