Any problems with painting intake?
I have my TPI unit all apart and while I have it apart I am going to clean up everything and repaint it. I was going to use dupli color high heat paint. Is there anything I shouldn't paint? I want to do the plenium, runners, fuel rails, throttle body, and the intake manifold.

I did my superram with Krylon. I did 2 coats of primer, and 2 coats of semi-flat black. So far it is good. I will powdercoat them the next time they come off. Just be REALLY careful of reinstalling them as the paint can get messed up easy.

Just do it but make sure the paint you use can tolerate solvents too.
I painted my TPI, AC bracket, alt bracket, thermostat housing. I am quite happy with it. I used VHT High Temp Engine Enamel. It says it can take 550 F and is solvent resistant. When the parts were dry to touch I put them to oven for coupe of hours to cure. After that the paint was really hard.
Be carefull not to paint any gasket surfaces or insides and injector mating surfaces of your fuel rail.

Re: Any problems with painting intake? (ToniH)
I was going to mask off all maiting surfaces and on the throttle body I was only going to paint the TPI badge. So it should be safe I am guessing. The paint I am using is "dupli color High heat paint with ceramic." It says its good for 1200 degrees but I doubt that.
One question though. It says for best results cure in the oven at 300 degrees for two hours. Is it safe to use a regular oven in you house or are they talking about a different type of oven?

I have no wife just a roomate that I don't like. I am moving from my apartment in one week so I don't care what happens to the stove. My only concern was if it would hurt my roomates health phisically. If not I am using it on an old cookie sheet.

Re: Any problems with painting intake? (85WHITEZ51)
I used dupli colors paint and I have to say while it came out looking great,the finish rubs/comes off too easy.I didnt bake the parts though so now im thinking maybe I should have done so to get it harder.
(That was the High heat 1200 degree paint)
You can use any good conventional oven but I would advise you to enusre the paint dries a bit before putting it in the oven for a bit.
You want the solvents to evaporate some before heating.

Re: Any problems with painting intake? (Bill's86Coupe)
I am using the same paint you did. It says for best results to bake it on so I will try that. I am letting it sun dry for two-three days before I would bake it on there. I do think baking it helps as I painted my thermost housing with this stuff a couple years back and it did like what you said untill I drove the car a few times then that stuff wouldn't come off without sand paper.

I also painted the TB itself. Little creative masking and i was able to protect the linkage and TPS-operating arm too (on the other end of the linkage). Of course I dismantled and totally cleaned the TB inside and out before painting and i painted the TB plate and IAC housing separately.
My paint didn't feel good until I did put it into oven. Even after 24 hours of drying naturally it felt like you could easily scratch it. In the oven it really melted -> hardened...now sandblasting is needed to get it off. I only heated the oven to 238*F (100*C) but it was enough with my paint.
I even ported the plenum after it was painted (because I forgot to do it before) and the paint didn't suffer my rough handling.
> It says its good for 1200 degrees but I doubt that.
The TPI will probably never get over 238F (unless its on fire ;) ) so if it can take 1200F or not is not an issue here. Instead, I would consentrate finding a paint that really claims to be solvent proof. I mean if you drop oil, brake fluid, fuel or coolant on it wrong paint will suffer or peal right off. The paints which are meant for engine blocks should be safe.

Re: Any problems with painting intake? (ToniH)
I had to reply back since Its brought up a few more thoughts.I have to say its hard to get that type of spray bomb or spray can paint to really last and resist chemicals to ensure it stays on a long time.
Even though I never baked my parts with the dupli color,I had figured since its on the TPI,it would get hot enough to bake it on.
Not the case.Gotta go with the oven baking next time.
ALso,Im the kind of guy that likes to use carb or brake cleaner to find vacuum leaks and that can also leave a mean streak in the paint so careful with that.it takes the paint off spray can finishes just as easy as brake fluid does but dries so fast it doesnt have time to lift it but leaves some nasty stuff there.
If anyone wants to see the dupli color shine on my engine,go to this site below and on the 2nd half is the motor in the car with bright aluminum high heat paint.It looks pretty good considering.(sorry if the pics on the site has faded..dont know what happened to them)
Im going to make a new site later and hope it will be a much better one. http://community.webtv.net/TunePort86/

Re: Any problems with painting intake? (jtjerry)
i Just took my first batch out of the oven. The paint IS much harder after being backed on then just letting it dry naturally. I painted the thermo housing with this stuff a year ago so I can make that judgment I just did. The can says it resist everything mentioned above so I am not to worried about it. I think you have to let the paint dry naturally for 24 hours then bake it on to get the results most of us are looking for. I will keep you posted on my resluts in the future. One word of cauting though be carefull with the parts after baking them untill they cool down all the way. I actidentally touched one part with a bakers mit and it messed up the paint. I think the baking process melts the paint down a bit because it was softer then than when I put the part in at first.

> 100*C YOU COULD EASY MAKE UNDER THE HOOD SIMPLE BY DRIVING
Yes, but not all paints cure properly in 100*C and secondly it doesn't still matter as 1200*F = 648.9 *C :)
> I think the baking process melts the paint down
I believe that happens too, when the perts were hot the paint was very soft but once it cooled down the paint hardened and no longer gets soft when the engine is hot.
Good luck with your project! :cheers:
