Etch Primer crazing!

[DraigFlag87]

Hi folks, just been refurbishing a set of Cinq wheels for the 126. I cleaned them, sanded them, cleaned them again with Fairy liquid, let them dry and now i'm applying the etch primer (Acid 8) before painting.

However after just 10 seconds it begins to craze and crack! Thought it might be better on the 2nd layer but again, as soon as it's applied it crazes. Any ideas? I only have a bit left, i don't want to waste it all!

Thanks

Don't really know much of this area, but would of imagined something along the lines of meths would of been best for removing any traces of grease left on the wheels, allowing the primer to act directly on the surface of the metal?

Washing up liquid will leave traces i'd imagine. Is it what it suggests to do on the tin of primer?

lol go a buy a tin of panel wipe its only a fiver a gallon, fairy will leave behind residues that react with paint

It just said use "detergent" to remove grease etc.

Live and learn i guess! I'm going to get some paint stripper today and then strip them back to bare metal. Then etch and paint again. Still got the lacquer left so lost £20 so far

Isn't etching primer just for plastic?

better lesson would be to take them to a powder coater and pay 20-30 a wheel to have powder coated

Maybe in London for that price, lucky to get it below £45 a wheel here

Also, maybe he's doing multi-colours, can't imagine that it'd be easy to powdercoat 2+ colours.

my place is no where near london. you have to go to a powder coaters not a wheel refurb place, local refurbers charge 70 a wheel and just take then to same place

Thanks for advise chaps. It's really not worth spending much on them, the wheels with new tyres only cost £50! And the paint cost £30 so it's becoming daft now (bearing in mind i'm currently spending a lot on other parts for the 126, and servicing the A500, where does it stop? )

Me thinks i'm going to strip them back again with paint stripper and then etch/paint again...

OK can use whiter spirit to degrease, and when applying the etch dry coats dusted on , not wet . this will avoid the crazing
