Por
no, not poor (that is a given in this hobby), but...
have any of you guys used POR-20 for headers? i just bought a pint to redo the crappy header job the ceramic coating guy did. i plan on wire brushing it down, sanding, metal prep and then POR-20. my body guy also warned me that the filling job the PO did on the exhaust ports may bust out with the heat of the BAS across there. so i am thinking of coating the back of the apron hoping to keep it cooler. may also buy a small sheet of heat shield to apply back there.
just curious if anyone else had tried POR-20 and your results.
