The POR stuff is the ticket! When you paint manifolds you are always going to have some flaking somewhere or you might spill something on them and have discolored or bare spots. The POR stuff goes on with a brush and when you crank up the engine it melts - so no brush strokes, and good adhesion. The big deal is when they need touched up, you just take a little paint brush, touch them up and crank up the engine - the new stuff melts into the old stuff seamlessly, and NO Masking off and overspray to deal with!!!
