We are contemplating coating a 4-layer board (signal,vcc,gnd,signal), .062 FR4 2 oz all layers, smobc. It's 100% thru-hole. The board carries about 2.5 amps. The board is placed in a commercial electric grill where contaminates such as grease and (ugh!) bugs are common. Is there a web site of reliable tutorial info on types of coatings, advantages/disadvantages, etc. I've found a couple of commercial sites, but need more objective info. Any help is much appreciated.
