I need to do some painting and trying to determine the best paint type for parts in the enclosed engine bay due to heat. I plan to primer with DP90LF then top coat with whatever works the best. For example; DBC, DCC, VHT, Rustoleum Engine, Rustoleum High Heat, etc.. What did the factory use? This is my daily driver so I want it to look nice and last but it doesn't need to be show quality. I do have spray equipment for gun spraying.

Radiator Core Support
Inner Wheelhouses
Firewall

Thanks....

 

Are you going black, or body color? Those surfaces were body color originally..

 

I would use the DP sealer with the DBC base and a good clear like DBC 2021.
With all the work, do it once. Although it doesnt make for a eazy touch up, but looks really nice.

 

I am repainting in black. The car is an all black car. I thought about base/clear but wasn't sure how well it would work close to the exhaust manifolds. Also, from what I could find, most engine paints seem to be enamel single stage instead of urethane 2K. I recently bent my front right corner so replacing the radiator core support. I will paint the replacement core out of the car and install it. Then, I will be pulling the engine and transmission so I can repair firewall to toe board area that is rusted out. After that repair I will be painting the inner wheelhouses and the firewall so I can use different types in the three areas if that works best.

 

PPG AUE-100/AUE-100LG...

 

Thanks for the info on AUE-100. I haven't heard of this before. I looked at the PDS but it isn't clear that this is compatible with DP90LF primer. I haven't found anybody that carries it yet to find out how pricey it is compared do DCC.

 

Just finished surfing the net and calling my local area paint suppliers. Nobody has the AUE paint that I can find. Wesco suggested Omni MTK for single stage. I think Omni has a base clear product also. Omni MTK is $80 a quart but they did say they have a cheaper product line (I think he said LumaBase).

 

PPG DCC9300
Shopline JAU 9300
Omni MTK 9300

 

Right now I am leaning towards Omni single stage. Anybody know anything about the LumaBase product?

 

I have not used the LumaBase.
The Omni should play well with the DP sealer, but always check the data sheets.
