Gelcoating inside Seacraft 20 cc

[capexcape]

I started out only going to gelcoat my deck, but got talked into doing all of the white inside my Seacraft.
It is mostly prepped ,- patched , flared ,sanded ect .
I have done the deck previously with good resultsby rolling .but now am faced with doing the whole inner liner.
I believe spraying would net the best results , but am looking for some pointers in regard to what type of gun ,and proper thinning ect .
Thanks in advance.
this board has given me great info on many facets of restoring my 20 master angler
