Came across this product in the thread regarding painting the spoilers

http://www.halfords.com/motoring/paints-body-repairs/car-rust-removal-treatment/hammerite-stonechip-shield-black-600ml#tab3


My plan was to liberally apply grease to my AC Pipes to halt/slow down corrosion, but having seen this product, i am think i should have really just have sprayed them with this before installing. I guess i could try to spray them in situ.

Or is there any reason why this would be a bad idea?

Depends how clean they are. If they are rusty already, covering it them with paint won't do much.

I would undo the brackets then you can move the pipes about. Clean them up, degrease and either apply spray zinc primer like Bilt Hamber Electrox (you don't have to get every speck of rust off as the zinc will neutralise corrosion as long as the metal is relatively clean). Or you could simply spray them in situ with an anti corrosion wax such as Bilt Hamber Dynax UC. This will keep water and salt off the pipes.

ac pipes don't rust, seeing as they're alloy.

hammers**te is horrible stuff, better off IMO getting them powdercoated.

Cheers they were new and have been on the car 4 months and a few hundred miles so should be in good condition. I haven't checked for a few months!

When i got the car i was told that the reason why most of the 6's don't have AC is corrosion of those pipes. I don't plan on selling my car so thought treating them with Dynax sound like an idea.

But thanks for those suggestions, we've got a flue at work that's corroding (looks like the wrong bolts used or something like that) so could use some of the Bilt Hamber stuff to clean up and fix ourselves.

They're on the car now - in hindsight that would have be the choice of champions Smile

I should have gone to specsavers, I was thinking of the power steering pipes across the front of the car that on my Rallye looked as though they had been pinched from the Titanic.

Agreed, Hammerite isn't great.

Was it the fact that the OE brackets were some metal which reacted with the alloy AC pipes and caused them to corrode?

I don't think so as they had a rubber liner, I think its just bare alloy that corrodes eventually, they are nearing 15 years old for the newest.

That's true...i'm guessing i#ll have other bits of my car to worry about than the AC Pipes LOL

But will give them a splash of some BH product at some point. No harm. Unless i manage to spray myself in the face with it, and then that might actually be an improvement Big grin

Would lacquering not do the same job? Just thinking it would make them looker nicer too where visible.

Oddly I can't recall seeing any with the metal parts corroded to make them leak, it always seems to be either holes in the rubber sections where they've perished or damage caused to the metal pipes.
