New paint job this winter for my 56

No, I got involved with the boat a couple of years after it was done, i do know Post paid for it at the time

Well, lets call Dock Wise and get it on down to Curacao!! That would save enough $$ to make it plausible. Plus he can go check out
Spanish Waters and the yacht club! (spelling)

2004 65' Viking convertible that the gel coat was stripped from the rub rail up and re-faired and painted with Kingston Grey Awl Grip 2000 and Snow White . Entire strip and top coat job was less than $115,000 plus consultancy fees and completed in two months time in Stuart, Fl. in 2015. OP was informed of this two weeks ago.

I certainly don't see ANY Barbara's.....just lots of Bob's.

Awl Fair and Awl Fair LW are epoxy based compounds that don't change properties for expansion, compression, thermal and tensile strength from minus 5 degrees to 68 degrees F. If the gel coat crazing is deep & severe enough that it extends down to the glass substrate than it really doesn't matter if your using a grinder with 40 grit or a 6 inch D.A. with 80 grit/ one method is a bit quicker than the other .
The contractor that performed the work on the Viking took the gel coat down to bare glass where needed in large areas like the forward brow and then smaller areas from the rub rail up. They machine sanded all of the effected surfaces down to a few mils from going all the way to bare glass. The attached photos show the process. wherever you see the reddish color than that's bare glass. Any bare glass areas were coated with Hull Gard and then 545 sanded and then Awl Fair was applied and machine / long boarded smooth..

Jonathan,
You and I have had this conversation via email and I believe that you know good and well what system was used. You know what the price was and who performed the work & where the work was done right down to what my consultancy fees were. Why are you keeping this thread alive by asking questions that have been answered previously in private?

Thank you BSD.
