Today I got an early start so I could complete 3 coats of POR-15 on the window channels.
I started by scrubbing the already clean channels (cleaned with Simple Green) with some Scotchbrite dipped in PPG DX-579 Metal Cleaner (same as Metalprep) to etch both the rusted areas and the clean bare metal areas as well.
Then to keep the Metal Cleaner and rinse water from finding it's way down into the body I plugged off all of the trim clip screw holes with some wooden matches (of all things!) wrapped with masking tape so they would seal up the holes. I left the matches in place during the POR-15 application to keep it from plugging up or reducing the size of the holes.
All of the pics were taken after the first coat of silver POR-15 was applied.
The 3 small holes on the passenger side rear window channel were patched with 2 layers of fiberglass cloth.
Driver's side bottom corner.
Heaviest pitting is right in front of the driver. I plan to sand this down after the POR-15 cures for about a week and put down a few more coats to level out the surface for a better seal when the new windshield is installed.
Front and rear channels with the first coat completed and waiting 2 to 3 hours for a second coat.
Right now it's time to put down the 3rd coat of POR-15 before the day/weekend is gone.
I
did call my Mom right after the second coat was down, Happy Mother's Day!
