Spraying cam covers

[riojin]

im planning on removing my cam covers off my gze and spraying them with some expensive heat resistant paint.

ive never done this before and am wondering if theres anything i need to do appart from unbolting them, removing them and after spraying them, replacing and bolting them back in?

[Hen is a total nutcase]

Clean the crap and oil off them before spraying. Brake cleaner and a rag or wire brush is a good bet. Then let them dry before painting too.

just painted mine a few days ago, if theyve never been off itl be a bit of a prick, just wedge a flat blade under the edge to lever them off, but yer just unbolt, clean up and paint, then back on. i used cheap as brake caliper paint, can take heat, looks tops

have you thought of powdercoating?

[awang]

sam sorry, is it powercoating or powdercoating?

powdercoating, that was a typo. I am thinking of going for a metalic black for my cam cover

Already thought of this and it will not take the heat. It will melt, not to an extent that it will run off, but it will become soft and eventually wont return to its baked hard state.

Remove them. Give the inside a quick degreasing, can use Brakeleen (brake cleaner) or degreaser or gasket stripper for this. Gasket stripper i've found is good for things like this, as it removes baked on carbon deposits and burnt on oil. Once the inside is cleaned (be it rough or perfectly clean) you want to clean the outside up real good. remember the result with paint is largely dependent on the prep work. I'd suggest the use of gasket stripper here, it'll need a few applications to get it real good. Spray it on and leave it. it'll buble the paint off from in the twin cam and toyota logos etc. If you've got a pressure cleaner use this to pressure clean it off, let it dry and re-apply the gasket stripper and pressure (wash) off, making sure you leave at least 15 minutes for the stripper to work. Once satisfied that it is all off and you let it dry, give it a quick rub with some sort of sand paper, could be emmry paper or anything really, just want to get a clean surface. Wipe down with some wax and grease remover. If you've got some handy use some etch primer, as i've found that using this makes even cheap pressure pack paint come up stunning! Then paint and let to dry! Install and :2thumbs: you're winning!!

wax and greese remover will do a good job to, i worked at a powder coating place and this is all we used to prep the metal (it was usually pretty clean though to start)

so id go with

-soapy water to get the chunky stuff off
-thinners to get any annoying bits off (stickers or something, gooey crap)
-wax and greese remover to finally prepare the metal

medwin - Would primer ever melt? With all the high temp stuff (engine block etc) Would it ever melt or bubble or stuff up? I have been thinking about this question for a while, and havent really come up with an answer.

I didint think the melting point was that low, but then again it is a plastic. I will try and find the melting point and post it
