Moz_Goodwood 0 Posted October 10, 2008 hiya all ive got a "unbreakable" exhaust manifold to fit to my 309 gti, but its got a fair bit of top rust and i want it all clean and tidy before it goes in the engine bay was wandering what options i have and what it will cost me (shot blasting etc) also afterwards id want to paint it and was wandering which paint could handle the temps cheers paul Share this post Link to post Share on other sites
welshpug 1,626 Posted October 10, 2008 lol, didnt buy it off ebay did you? I saw one advertised as that and it has a section of the strengthening missing its cast iron, so it'll always be that colour unless you paint it Share this post Link to post Share on other sites
projectpug 0 Posted October 10, 2008 If it were me i would remove the surface rust in a few ways, wet/dry sanding dremel that sort of thing. Then a few coats of hightemp paint would do the trick it can be bought in loads of different colours too . The more time you spend on the prep of the manifold though the betterthe finish.

jord294 87 Posted October 10, 2008 i've had a couple shot blasted for my cars as long as vht paint is applied before any dampness settles on it, it should last a very long time Share this post Link to post Share on other sites
Moz_Goodwood 0 Posted October 10, 2008 @ welshpug, no mate ive had this kicking around the garage for a while now, but it was that advert that reminded me ive got it and the "unbreakable" tag made me chuckle projectpug, the wet 'n' dry sounds good mate but im a lazy tw@t and was thinking along the lines of shot blasting or like some sort of acid dipping (not sure what the exact term is) which would help clean the inside aswell Share this post Link to post Share on other sites
Miles 331 1 Cars Posted October 10, 2008 Also worth getting the face, faced off as they are not very flat and the ports can eat away around the gasket area Share this post Link to post Share on other sites
GLPoomobile 958 Posted October 10, 2008 I'm awaiting a tub of Bilt Hamber Deox C. Cost me just over a tenner. You stick a few scoops in water, put the rusty item in the solution, wait 24 hours, and it's supposed to come out good as new. Sounds like s*ite, eh? But a guy who I work with says he stuck a rusty old downpipe in some Deox C and it worked a treat. Share this post Link to post Share on other sites
Moz_Goodwood 0 Posted October 11, 2008 sounds interesting, where did you get your deox c from? i take it most engineering places will skim the face of it Share this post Link to post Share on other sites
