Howdt SC,
I actually use 2,the first is a thin coat then I use a thick coat for the second.
despite how tough epoxy is it does chip kinda easy if the coats are too thick.
sometimes the finish is not 100% after 2 coats then I scuff the surface with a sanding sponge then try again with some heat.
it usually does work the third time.
I have some shots to send to Mont,some that no one has seen. I'll also share my "oddities" shots too,some really cool Fat baby P-Knutts for sure and all of them swim!
