SiWhite Posted January 25, 2006 Share Posted January 25, 2006 I've used a generic 'special metals primer' on plated parts before, before a topcoat of your favorite paint. Worked well for me. Having small parts re-plated really isn't very expensive. Quote Link to comment Share on other sites More sharing options...
ripley Posted January 25, 2006 Share Posted January 25, 2006 Tony, ive painted all my steering bars & diff guards etc in 2K & considering its underneath there standing up well, if they were painted in a solid colour High Solids(2K HS)not metallic as they are, it would not come off at all, to increase durability of the paint you reduce the bake tempreture & use a slower activator, it increases the strenght of the paint surface more than you would believe, other than cars we also paint sports boats & Jet Skis, the skis we do for the RNLI get a lot of abuse, but the paint hardly ever looks marked(they come in ever 2yrs for a refurb), if you ever want any bits painted how ever large or small, give me a call Regards Graham Quote Link to comment Share on other sites More sharing options...

Mark Posted January 25, 2006 Share Posted January 25, 2006 There are severla 'cold galvanising' paints around; glavafroid as you say. Rustoleum do a spray zinc paint, and Wurth also do something called Zinc Hell which is designed for painting welds on previously galvanised things. I havn't used galvafroid, but I have used both the others, and they work well. The rustolem came from an industial paint supplier, and the Wurth stuff came from City Electrical Factors! Other than that, as has been suggested, either a special metals primer, or an etch primer, and paint it as normal. Halfords do a tin of etch primer which is very handy to have in the (coshh?) cupboard... ta Mark Quote Link to comment Share on other sites More sharing options...
white90 Posted January 25, 2006 Author Share Posted January 25, 2006 Galvafroid it is I went and got some today first coat on 2nd tomorrow then top coat if required, I may paint them black if the galvafroid takes ok. Quote Link to comment Share on other sites More sharing options...
Nick Ninety Posted January 25, 2006 Share Posted January 25, 2006 Used Galvafroid to spray up the bulkhead for my 90 rebuild and primed & sprayed over the top. So far so good. Think there is a warning about over painting using certain paints on the tin. Was really surprised by the weight of the tin, must be all zinc in it.

LR90 Posted January 25, 2006 Share Posted January 25, 2006 What are the views on red oxide? That would have been my pref or am I just out of touch with modern paints? Quote Link to comment Share on other sites More sharing options...
