OMFG, I just got back from this shop.. the guy says he guesses this project would run about 15-20 hours, at a rate of $75/hour..
He said it will probably be over $1000... SHEEESH!! COME ON!
He obviously failed to realize the simplicity of this project, probably because he was busy, but whatever..
I'm not taking this stuff for granted, I mean it is difficult, but I cannot see a skilled fabricator spending more than 6 hours on this (excluding curing time)..
The tricky part is the 1st part, which I'm struggling with as you may have noticed..
After you get the right shape, it's pretty simple to fit the piece in, sand it, and prep it for paint..
I might have to use expanding foam or short-strand marglass/everglass to make my mold/tub and then glass inside that.
