Painting/sealing inside of CMP doors?

[Jordan Baker]

Just looking for any advice/suggestions on how to paint/seal the inside of the CMP doors?

I've got the body work complete for my drivers side door and will be coating the exterior in POR shortly.

Did you ever consider coating the inside of the doors with Krown Rust Preventative?
It is available in a spray can from any Krown dealer.

Hi Jordan

I removed the door latch assembles, taped up all the holes, but one, poured in quart of POR 15 sealed the last hole then rotated the door slowly in all directions. Then drain the excess and repeat with the next door.

Just be sure you are done welding on the door.

Note- Please read Jordan's response, down two, I must have been lucky and used better tape but the lesson is well put use really good tape and clean the metal on the outside first.

Cheers Phil

PS Tell you how it worked at preventing rust in about 50 years.

Thanks for the suggestions.

Well I tried the tape up all the holes and pour in a quart trick. I poured in about half a quart when I realized the duct tape I was using didn't hold and I leaked all over the floor. I stopped poring and began rotating. Inside is completely coated in POR15 along with some of the floor.

One door down, one to go (outside that is)

Hi Jordan

Thanks for the follow up and the picture, how much paint did you get on yourself in the process?

Years ago I tried this trick using LPS-3 which is a cosmoline like rust inhibitor on Jeep Truck doors worked but when ever the truck was parked in the sun it smelled like cosmoline and on a real sunny day in the summer it dripped. The real problem was that tried to weld on door a couple of years later and the inside of the door caught fire. Rest of the truck rusted away but the doors never rusted.

My approach to POR the inside of cab 13 doors was a bit different.
I needed to do dent repair to one door and reskin the other so both doors were separated into inner and outer panels. After getting the individual parts in satisfactory condition I PORed most of the door, leaving a narrow ribbon bare to allow for the folded edge and spot welding. After folding and welding I poured a smaller quantity of POR (actually leftover fuel tank sealer from Bob's truck) and tilted to cover the inner part of the seam. None came out except at the ends that I'd left open as telltales. Now I wonder whether that means I had such a tight seam that I didn't get penetration of the POR.....
