J Posted September 29, 2003 Report Share Posted September 29, 2003 I have looked into powdercoating shit in my engine bay, but i have read that it is a great insulator, thus keeping heat in my engine and plenum, correct? How do some of ya'll feel about this? Thanks Jay Quote Link to comment Share on other sites More sharing options...
1uvakind Posted September 29, 2003 Report Share Posted September 29, 2003 i have heard that as well, but then again i know of many car amplifier manufacturers that powder coat their amps, so either its not as bad as we think or they have some special method that doesn't trap the heat. i would like to know more as well, cause i am looking into that too.

RedZMonte Posted September 29, 2003 Report Share Posted September 29, 2003 Powder coating does not create a heat barror. on the other had a Ceramic/Jet coating does. RedZ Quote Link to comment Share on other sites More sharing options...
2bluecutlass Posted September 30, 2003 Report Share Posted September 30, 2003 Since I had my intake manifold off to fix the coolant leak, I figured, I might as well make it look better, so I used the high heat aluminum paint from autozone, in the matching dull aluminum color of the factory. The layer of paint is so thin, I doubt the air will warm up enough to make any difference to the engine. Heat transfer depends on these variables, difference in temp between the two areas, the flow rate, and the materials. Any coating you use, just for color, should be ok. If you use something else thick,like bondo(LOL) you could heat it up. Enjoy! Quote Link to comment Share on other sites More sharing options...
J Posted September 30, 2003 Author Report Share Posted September 30, 2003 paint is different, powdercoat is baked on to form a hard shell, thats like when i see someone with a chrome alt i just have to laugh, heat with alt=dead alt chrome = retained heat.

1uvakind Posted October 1, 2003 Report Share Posted October 1, 2003 yes and powder coat is just what it says... powder, which fills the cracks and pores of the metal you are coating thereby not allowing it to "breathe", powder coating retains all the heat, doesn't let it escape.

PaPaPooh Posted October 1, 2003 Report Share Posted October 1, 2003 i used to powder coat semi wheels at a michelen (sp?) plant IIRC the powder has to be baked on at 550 degrees F they cooled down in about 10 minutes when i had to grab them to stack on the skids (pallets) to be banded and shipped it was a cool job and easy to powder coat with the right tools just thought i would add that have any questions i will try to answer them the best i can Quote Link to comment Share on other sites More sharing options...
timbit_69 Posted October 4, 2003 Report Share Posted October 4, 2003 where i work right now Powder coats and paints the LAV's that are made by GDLS(General Dynamics Land Syastems)/ The old GM defence... Powder coating is much better than regular paint and last alot longer bc it is bonded with the metal. Yes the powder coating will retain heat better than just paint, but that diffrence shouldn't effect your engine at all. the only thing that it might change is if the place you get it done doesn't protect the mating surfaces of the parts it will create gaps between the suffaces and that could lead to leaks-even if ther is a gasket between them. For example i got my headders sand blasted and powder coated, and had a ceramic coating put one the inside of the headders, if i got them back with some of the powder coating on the mating surface of the flange i could have a leak, but fortunatly i havent, and i also inspected them before i left the shop. Things like Headders and exhaust should and can be ceramic coated, that will keep the heat inside the headders and not in your engine bay. the ceramic coating on the inside also smooths out the flow of your exhaust.
