I originally had plans to undercoat my car with POR-15 but now I'm wondering if powdercoating might be better. My goal is to make it all bulletproof. Do any of you guys have experience with powdercoating vs. POR-15?

Powdercoating is the way to go.. no doubt about it

But I've never heard of someone powdercoating the undercarige of a vehicle before. You know that powdercoated parts need to go into an oven at 300*+ to cure right? If you were able to find someone with an oven that big, you'll need to make sure every last bit of rubber and plastic has been removed from the body.

Also, powdercoat needs a good surface to adhere to. Freshly sandblasted, etc.

Someone on this board recently powdercoated their floor and framerails. I can't remember if there were pics or not though. THe price was cheaper than I expected. A search should turn that up.

There are some places that will use a localized heat source to cure the powdercoat. If they are putting it into an oven, they'll need to bring the temp up slowly and down slowly so that there is less tendancy for straight panels to buckle I'd think.

Eastwood used to sell a heater on a stand to cure parts too big to stick into a conventional oven that most DIY'ers would have access to. It would seem to be harder to control the temperature though.

I did the entire underside, axle, housing, brake parts, steering gear, inside floor boards, and the engine bay. I used one and a half quarts for the entire project. I guaroonnteee you cannot find a better deal. (If you are willing to get under there and wire wheel, scrape, heat and scrape some more, wash, then prep all the metal.)

Unless you have a media blaster.... that would have been nice... next time. But, either way the surface has to be prep'd before either surface treatment is started.

here is a pic of the underside using Por-15. Excuse the red circle, it was from another thread on subframe connectors.

If you scratch it you can touch up POR15.

I did the under carrage of my car in POR 15, Though there is a little rust creap in some areas which I am a little dissappointed about to say the least. I used Eastwoods rust encapsulater on the interior and engine bay, and I am very happy with it. Also it's very nice because you can spray it on with out the need to purchase special thinner from eastwood. It is also fairly tough.

Believe it or not POR-15 actually has a better chemical adhesion to rusted metal than bare metal. now if your floorboards are rotted out don't slap some on their and expect it to be tough, but some surface rust is defenitely a benefit
