As mentioned in my thread about my minis I am stripping paint off my mini's engine bay, however due to the factory primer being quite resistant, I am not bare metalling it all. The question is can I give a coat of etch primer even on the painted areas or do I have to put it only on the exposed metal bits?

Rather than etch primer, try Epoxy primer. You can leave it for six months then if you wish, without topcoat.

Hi yes I know but I will not be leaving it, it'll get painted the day after with primer and then the day after with the actual colour. Furthermore I already have etch primer on the shelf from a previous project, I am just doing the engine bay on one of my minis so do not need much!
So can I paint etch primer on previous coatings or just on the exposed steel?

Hi Bob

Etch primer is fine over previous coating, unless there is a paint reaction, so put a blob of etch on the previous coat to test.

hi bob

ive recently used etch primer over some repreped areas where there was a mix of painted and non painted areas. it went on fine after making sure the surface was free from contaminates (panel wiped and degreased)
the etch primer i used was acrylic based however

try it is best

Hi Bob2,

Yes I have just painted over a mix of bare steel and rubbed down paint
with aerosol etch primer, and I have had no reaction (apart from the wifes
reaction ~ she made me hoover all the prep dust off the drive)




Cheers Steve

Thanks all for the replies will try it over the wkend on the areas I'm almost ready from then!!
I'm only half way through, yesterday I got fed up of sanding and started degreasing the engine instead!

Hey d4b I will not have any sort of reaction then as I am doing it in a lock up away from home
