With the motor out of the boat for improvements, I thought I would spiff up the engine compartment and bilge. I know Interlux makes Bilgekote but I have a fresh gallon of 2 part white Primekote. I bought it for another project that never materialized. Since I've got $70 in the Primekote, can it be used as a stand alone for what I want to do? The current finish is a gray base with white splatter coat.
