considering coating the pistons for my build. gen 3 hemi under bewst. intercooled. 9:1 comp. what do you guys think about thermal coating. this gen 3 and bewst will be new to me so there will be a learning curve thinking about it for insurance but would it be a waste ? its a reverse dome forged piston with side skirts already coated.
