Hello,

I'm at the stage now where I am rubbing back all of the tatty bit's on the underside of my Cossie before paint.

On the spare wheel bowl (under car) after I rubbed it back, it has slight pitting on the metal.

Am I right in thinking - Acid etch then High Build primer over the pitted areas then rub back?

It's just, I was told from the paint supllier to put body colour onto acid ecth after around 4-6 hours whilst it was still tacky and before it cures?

 

Probably because etch is hygroscopic so will start to absorb moisture from the atmosphere if left exposed. There's no reason why you cant overpaint with a high build primer though. Best thing is to get the data sheets for all the paint you're using so you know exactly what you're doing.

 

any bare metal on the underside you want to have acidd etched really, nigh build prmer is fine on top then colour and laquer if needed

 

makes sense to me

anyone else come across this, surley I can't be the only one?

 

I have used high build on top of etch primer when I've been refurbishing scabby alloy wheels and never had a problem!

 

i took the complete underside of my escos back to bar metal and did what i said above, but before i hih build primered it i sealed with with sealent and brushable seam sealent

link here if you want to see what was involved, carnt remember what page so just scout through them until you see the car on its side
