this is one of my favorite auto body/fiberglass tricks... its a bit messy but works great!
You hate putting body filler on only to have to sand it down carefully to remove all the ridges and divots you created by spreading it?
Here is my solution, I call it the "milkshake" as it looks like a strawberry milkshake. Basically what you do is mix about 50/50 body filler and fiberglass resin till it becomes about as thick as a milkshake, add the respective hardeners, and brush it on. It self levels, is easy to sand, and wont crack if it gets thicker than 1/4" like regular filler..
