About a year ago, there was quite a bit of discussion about my problem with streaks on the body cladding of my Pontiac Montana van.
The fix was what I hadn't really wanted to do, but now that it is done, I couldn't be more pleased with the results.:yay
Last Saturday, I masked off the panels and refinished them. It was a major project for me and if I hadn't had the assistance of a good friend, I doubt that I would have even tackled it.
The products used were SEM and I used their recommended products and steps.
First, we cleaned the panels twice with a degreaser and wax remover, then used the SEM products according to the following instructions they e-mailed me.
1. Clean all surfaces to be recoated with 39362 SEM Soap, along with a
gray scuff pad. (We did this twice.)
2. Apply 38353 Plastic/Leather Prep, then remove with a clean, lint-free towel, wiping in one direction only. (This was a cleaning agent so we did this twice as well)
3. Apply a light coat of 39863 Plastic Adhesion Promoter, allow to flash 5
minutes, then apply a wet coat. Allow to flash 10-15 minutes, but no longer than 30 minutes before topcoating.
4. After the final coat of 39863 Plastic Adhesion Promoter has flashed
properly, apply a light coat of Bumper Coater and allow to flash for 5
minutes. Apply one or two additional coats, allowing 5 minutes between
coats. You are now finished with the recoating process.
In my case, it took 7 coats for complete coverage. I went ahead and applied a total of 10 since that used up all the Bumper Coater. It's quite possible that I didn't apply heavy enough coats to get the coverage, but I didn't want any sags or runs. I had none and it is close to a flawless finish.
Total time was about 5 hours, but at least 1.5 to 2 hours were in the masking and the removal of the headlight/parking light assemblies to do the front bumper and final clean-up.
I would recommend the SEM system, but I do think using all the products as recommended is a good idea.
It doesn't take much of the soap, plastic prep or adhesion promoter. I needed only one of each. I did use 5 spray cans of the Bumper Coater, though.
I didn't post any pictures. It looks good, but it should since they are newly painted panels.
