I use a Sata shutz gun with wand attachéd to it. I put epoxy in the cup then when you spray it it comes out of the end of the wand in an oval shape pattern and covers the inside of the doors or any other inner area that you want covered.

I've brushed epoxy primer on hard to reach areas before with great success. POR 15 is not really the correct product to use. With a properly prepped surface, nothing will be better than epoxy primer.

what epoxy did you use? How did you properly prep it in the hard to reach corners? thanks

I have been using Dupont DTM epoxy. That stuff is tough as nails. However, I do have a problem with it. If you purchase a gallon of it along with the catalyst, then plan to use it fairly quickly. The epoxy itself has a long shelf life, but the catalyst does not. It mixes 4:1, so one gallon of epoxy and two quarts of catalyst. I overcame, a bit, the problem with the catalyst by only purchasing one quart at a time. My project moves at a snails pace, so I learned to only purchase my paint products when I plan to use them.

As for properly prepping the surfaces, the door shell would be a great candidate to media blasting the inside and the back side of the door shell. I wouldn't do the skin of the door though. If you don't have access to a media blaster, then you'll just have to get in there best you can with sandpaper. However, the only proper way to reach in the crevices of the door cavity is with a media blaster.

POR 15 requires the same amount of prep as applying epoxy. I view, and many experts view, POR 15 as almost being a 'Snake Oil' product. If you plan to use some type of acid based rust converter, then make well sure the epoxy will adhere to such surface. Same with soda blasting. If you read the MSDS of several paint products, you'll see manufacturers do not warrant their product over and acid prepped metal or soda blasted metal.

It's best, when restoring a car, to have all your paint products picked out and fully researched before you take on the project. That way, you will not have to endure any ill-effects of product incompatibility.

I've also read good things about "flooding" the bottom of the door. You just pour in epoxy and rock the door back and forth so it will fill up the seam where the skin meets the door. Seems to be where most rust starts, it's almost like caulking the door.

I have been reading a lot about a product made by eastwood that looks like it will fit the bill. I have used in all off the nooks and crannies that I can't reach any other way. The extension nozzle tubing makes it real easy to get those hidden spots. Take plenty of time to put a tarp down below your work. It's messy. http://www.eastwood.com/internal-fra...nozzle-qt.html
