Title: Hammerite versus petrol tank plastic
Post by: dadrathers on 29 August 2011, 19:41

My petrol tank straps are rusty (no surprise). I have been toying with the idea of painting them with Hammerite but I am a bit concerned that the paint or rather the solvents it contains might react with the plastic of the petrol tank.

Does anybody know whether they react or is Hammerite on tank straps standard practice?

Cheers.

 High density polyethylene (HDPE) fuel tanks are pretty much bullet prof to everything except bullets! Hammerite is a spirit derived product, that can be used on plastic guttering etc, I would say that the paint would dry out, long before any unlikely chemical reaction would ever take place, and not to worry about it...

hammerite is fine on most things.. but from what ive read its not the best thing out there for protecting metals subjected to the elements..

Can you suggest what would be better, Tech1889, without having to make massive surface prep - ta.

Dinitrol is very highly rated as it doesnt go hard and split like hammerite

take old straps off,  use as template to make stainless one,  fit stainless ones throw old ones away.  sorted  no surface prep at all

This has reminded me that I must do mine.

I was thinking of getting a second set, cleaning them and getting them powder coated.

Yeah - I would have taken them off to clean them up but I didn't fancy my chances of undoing the bolts that hold them on and did not want to have to drop the tank.

New ones are still available from VW at nearly 20 quid each.

i took mine off when i painted them.
just put a jack under the tank to support it when you take it off,that way you dont need to drop the tank and its already in the right place for the straps to fit when you put them back on.

That just leaves the rusty old bolts then.

Painted them in situ now - looks good but I got nearly as much paint on me as on the straps. :grin:
