SHGWAG Posted January 11, 2010 Share Posted January 11, 2010 Yuh, need the inside of one of my intercooler pipes painted / coated. Anyone had this done before?? I'm thinking either: Powderocating (not sure if its feasible due to the bends in the pipe) HPC coated (same problem as above) Hot Dip Galvanised (would most likely warp the pipe) GO!

Testament Posted January 11, 2010 Share Posted January 11, 2010 galv would be ok mayeb - but dont coat the inside with paint/powercoat at all. maybe fish oil if you want to stop rust. too much risk of paint coming off and wrecking your engine - it's happened many times before.

SHGWAG Posted January 11, 2010 Author Share Posted January 11, 2010 Fish oil? Yea, wasn't too keen on paint idea. just worried about the galv being too hot & warping the pipe as i have sweet FA clearance as it is. Quote Link to comment Share on other sites More sharing options...
Testament Posted January 11, 2010 Share Posted January 11, 2010 yeah fish oil. you can buy it at ripco/superchump etc. or CRC longife or Inox, or moreys/chain lube/used diff oil etc. whatever your chosen rust preventative oil product is. intakes get kind of oilly anyways so it's not critical.

SHGWAG Posted January 11, 2010 Author Share Posted January 11, 2010 Cheers, I will look into this / Talk to the Galv guys tomorrow & see what they can do for me. Quote Link to comment Share on other sites More sharing options...
Testament Posted January 11, 2010 Share Posted January 11, 2010 I really cant see it being worth galving it unless they do it for free at work. and even then it's of dubious worth. its not going to drop rust flakes into your engine unless you leave it sitting somewhere moist for 100 years without running it. e.g. most old cars had cast iron intake manifolds with no paint inside i.e. it doesn't matter.

SHGWAG Posted January 11, 2010 Author Share Posted January 11, 2010 You have a good point, however I want to be safe rather than sorry, don't want to have to shell out over a G for a new turbo. Quote Link to comment Share on other sites More sharing options...
tortron Posted January 11, 2010 Share Posted January 11, 2010 por15 perhaps or even a petrol tank sealer Quote Link to comment Share on other sites More sharing options...
Testament Posted January 11, 2010 Share Posted January 11, 2010 get an aluminium or stainless steel bend instead? Quote Link to comment Share on other sites More sharing options...
sheepers Posted January 11, 2010 Share Posted January 11, 2010 do not POR 15. it wont stick to smooth surfaces, like new steel pipe work. just leave the inside, it wont rust up to bad. and youll be taking them off again in a month or two so you can clean them up then. sheepers.

tortron Posted January 11, 2010 Share Posted January 11, 2010 do not POR 15.sheepers. no reason it wouldnt stick to a correctly prepared surface Quote Link to comment Share on other sites More sharing options...
bubblegoose Posted January 11, 2010 Share Posted January 11, 2010 push a rag soaked in rust converter through the pipe then push a clean rag though will stop rust but wont be enough shit left inside to flake off Quote Link to comment Share on other sites More sharing options...
Hemi Posted January 11, 2010 Share Posted January 11, 2010 could also use that soft seal stuff , works pretty good . comes off with solvents. stopped my splines and shit from rusting when i was storing them Quote Link to comment Share on other sites More sharing options...
sentra Posted January 11, 2010 Share Posted January 11, 2010 galv probly has more chance of flaking than nothing Quote Link to comment Share on other sites More sharing options...
sheepers Posted January 11, 2010 Share Posted January 11, 2010 do not POR 15.sheepers. no reason it wouldn't stick to a correctly prepared surface your absolutely right, but a "correctly prepared surface" would require the inside of the pipe being heavily scored with the likes of 40 gritt sand paper or better. any parts you miss with the sand paper then paint with POR 15 will come off and make their way into the spencive bits called the engine. like i say, POR 15 wont stick to any smooth surface, it has to be fucking rough before it will stick. new steel = not even slightly rough enough.

SHGWAG Posted January 11, 2010 Author Share Posted January 11, 2010 get an aluminium or stainless steel bend instead? Its a 2 foot length of long pipe with numerous bends etc.. Will just grease it up untill I can afford to get one made up out of stainless Quote Link to comment Share on other sites More sharing options...

You could maybe use Por 15 metal ready and not paint it, not sure how long it would prevent rust without coating but id hazard a guess at forever in an oily intake. After treating you just wash the part with water - too easy. Its the only rust stuff i use now. Hate that rust converter shit - always dries and leaves a film and its fukn hard to tell if you got all the rust underneath - usually not. Pretty dear but its fully reusable so lasts ages. Their marine clean is awesome too, if there is any residue on the steel i would recommend using this before hand. Quote Link to comment Share on other sites More sharing options...
drftnmaz Posted January 11, 2010 Share Posted January 11, 2010 just use oil.... too much chance of anything else flaking off, i just oil my pipes if ther not going on straight away, and then paint the outside... once its running it will oil on its own Quote Link to comment Share on other sites More sharing options...
forced Posted January 12, 2010 Share Posted January 12, 2010 Some factory intercooler piping is mild steel. On mine I cant see much inside due to the film of oil that looks like it's been there from day one. Steve Quote Link to comment Share on other sites More sharing options...
