Hi all, its nearly painting time and I have been busy prepping the heads/barrels/cases on my Shadow motor.Question is what type of paint?There seems to be a general agreement on 2 pack acrylic/polyurethane (whatever that is-i,m no expert here!)Does this cope with the heat etc? My painter had a trial run on a couple of small items,:blast/etch prime/ top coat. No primer used as I dont want to build up too much paint on the motor for obvious reasons, results good but the paint sank into the pores on the clutch cover and spoiled the finish in places.My painter advises primer to get round this.Maybe OK on the outer cases that are smoothly finised, but I am reluctant with the heads barrels as they are cast finish anyway(original paint prior to stripping was very thin)....Any pearls of wisdom on this one? Thanks, Bob.
