Vapor Barrier
Hello everyone! I took off my crummy door panels yesterday to fix a window regulator and noticed the vapor barrier has never been removed. I removed this completely on my vert with no ill effects. Just wondering, does it really serve a useful purpose?

Damn, it did start!
The pressboard door card I'm sure appreciates the protection from the moisture that find it's way into the door.

Living in AZ will help
Bear in mind that water WILL go into the door cavity every time you WASH it tho. I replaced my failing plastic covers with 6ml poly. If not too late, keep one of the old ones as a template, buy some black silicone and re-do it. BTW a great time to clean out (heck, I WAXED mine!) the insides of the door and check and seal the bottom seam for internal rust.
I used POR 15 for that. Also lube the window regulator at the same time and lined the door with sound protection...

that being said the vapor barrier is just a sheet of flat plastic on the 1st gen. Mazda's glue is a PITA, but if you spray it with water while you're working on the car it will keep it from being sticky.

Alrighty then not what I expected! I plan on making my own door panels with some extra epoxy glass laying around the shop. I'll make sure to line the outer edge with universal weatherstripping. As for the bottom seam inside the door, what did you use to reseal it?

Details on their site, but basically, clean out the old dirt and munge, light sand if there is any substantial rust build up, clean up with their Degreaser, prep the surface with their MetalPrep etcher, then paint on the POR with a small brush. For your project they offer a perfect starter kit with everything above for about $22.
