    Not good to paint an engine head ?

    Today I go to my Honda dealer to take my oversize and piston (125m) and other part (pic coming soon) and I told to the guy for painting tips. And he told me is not a good Idea to paint the head ? It is real The guy say is for the cooling.

    Do you trouble with your head painting ?

    Ps- Im very scared to paint a new oversie cylinder head. (For paint in the cylinder or in the gasket area) What do you think


    Thanks

    Paint it flat black so it radiates the most heat.

    as long as its engine paint its good, also you should prime it up before painting comes out really nice, then a clear coat.

    whaaaa???? you cant go priming a head. the paint can take high temps but the primer wont. ive learned that the hard way. but again i did it on 2 stroke sled heads.
    down to parts because i no longer have a place to ride trikes.

    You can get high heat primer, I never prime it though. The duplicolor bakes on real nice and dosent scratch off very easily.

    Rob (84Honda200s) is absolutely right. The primer will not withstand the high heat on an engine head and cylinder. You simply sand the head down with some high-grit paper. Also, be sure to degrease and clean everything with solvent, otherwise the paint won't stick.

    Clear coat will also not last on the engine, I don't think. 2 coats of Engine Paint will do fine.

    Paint does retain heat... but I doubt you will notice any difference... I would personally leave it bare... to each his own...
