Nice Project Mate will be a Keeper for Sure..
Divots could be caused by a few things,
one Is the clear simply filling all the holes and cracks between the inserts etc which may take a few coats to fill,
The other Dreaded cause of whats known in the paint industry as "Fisheyes"
This is generally caused by silicone still on the surface as a resuidue from polishes..
When painting automotive paints you add silicone remover drops to the mixed paints..
I personally would also use prepsol over shellite to prep the surface too..
Im not 100% sure on shellite may still have an oily residue ....which will cause fisheyes
Just my .02c
Good Luck!
