In part 1, we prepped the floor pan by cleaning and removing as much rust as possible, applying Marine Clean and Metal Ready. After allowing it to thoroughly dry, we applied the POR 15 coating.
The POR 15 directions state that if the metal has been sandblasted to bare metal, the Marine Clean and Metal prep stages can be skipped and move straight to the POR 15 stage.
Applying POR 15 To Floor Pan
There are basically 3 ways to apply POR 15. You can spray with a spray gun or airless sprayer, roll it on with a paint roller, or brush it on with a paint brush. We decided to use the brush method and it worked well. The paint brush streaks flow out and it looks good. However, we were not too worried about how it looks, as we are going to cover most of the areas we coated anyway.
Here are the steps we took:
1. Wear PPE (gloves, respirator, etc.)
2. Mask or protect floor or areas that you do not want the POR 15 to get on. (We got some on the floor and it is hard to get off.)
3. Mix coating using a paint stick. (Do not shake or place on a shaker)
4. Apply 1 coat using a paint brush to all areas that were prepped and ready.
5. Allow to dry 2 to 6 hours (dry to touch) and then apply a 2nd coat.
That’s it, now allow it to dry. It will dry to a hard coating. That was our first time to use this specific brand and I think it worked well. I had a few comments from part of of other products to try, which I may in an upcoming video.
We do have a few rust holes to go back and weld in new metal. We also need to prime and apply seam sealer to all seams in the floor pan. Then we are going to lay down dynamat or something simmilar to reduce heat and noise into the passanger compartment.

August 20, 2013 at 11:40 pmHi Donnie….Nice video on Por-15. I was going to use Por-15 on my 66 Mustang Coupe but elected to use MasterCoat Permanent Rust Sealer Surfacer from PM Industries. I used the Silver on the roof. I used a spray gun to lay several coats. The MCU is best for body work. Once sprayed the roof will never rust again. I have some before and after photos if you’re interested to view.
Thanks for the lessons. I’m most interested in your 66 Mustang project as I too am restoring a 66.
