To Acid Etch, to not Acid Etch...

Planning on refurbing my Cam Cover in VHT Wrinkle Red.

Red a few online guides. I was going to use Upol Acid #8 Primer, but half the guides i have read say no need with VHT Wrinkle, just spray on.

I feel that with a primer the bond will be better, but having read the Halford's website it says it is unsuitable for an engine block. I know it is the cam cover, but obviously it still gets very hot. http://www.halfords.com/webapp/wcs/stor ... 65625#tab4

Any thoughts chaps?

acid etch for bare metal, cant see it doing any harm to the VHT

actually I think I have used normal vht over the top of acid etch before

Acid etch all the way.

I acid etch all rocker covers i do with BH Etchweld.
Be careful. Wrinkle red is an absolute bitch to get the wrinkles even.

Is BH better than Upol? I also have a rusty old patio table that I have sanded and needs priming and painting.

Plan is to do one cam cover in wrinkle red and a second one to try and replicate the strut bar, I can then see which looks best.

Hoping to rattle can spray the cam cover in black, then using a tin of red car paint, go at it Jackson Pollock style throwing paint from an old hard brush, and then clear coat lacquer when dry. Unless someone has a better idea?

If it all goes tits up, then I will strip the spare and VHT wrinkle red that one as well, put the best looking one on the car and eBay the other.

Go with the Jackson Pollock idea, at least it's different!

Yeah but it might end up jobby!

In an ideal world I'd have a stack of covers to practise on, but in the real world it is the one on the car and a spare!

Then it'll look... wait for it... wait for it... Pollocks. Hurr.

Back to seriousness though... do your good one properly and J-Pol up the spare and THEN you can see about swapping it and putting your good WR one on eBay?

I never bothered when I redid mine but the were bead blasted and then cleaned, so they had a good key. Just ask Tin Tin about his one.
