My firewall has been painted six or eight weeks but I had failed to cut the 2 1/4" hole needed for the brake booster push rod.
I had a 2 1/4" chassis punch so cutting the hole was no big deal. The interesting thing is my son in law, Tim, was here for thanksgiving dinner and I was showing him what I had done. I looked at the plug and realised there was absolutely no loss of adhesion anywhere. The red epoxy on the bare metal, the red epoxy on top of the body filler, as well as the dark red base and Universal Clear had all maintained their adhesion.
The only failure of material on the plug was the body filler fractured from the severe bend in the metal. This is a pretty awsome testimoney to the quality of the SPI line.
Here is the firewall side if the plug. Note, the only seperation is the body filler seperated between the layers of SPI epoxy. The epoxy, base color and clear all maintained adhesion.
Here is the interior side of the plug.
I would estimate the body filler is approximately 1/16 of an inch thick and the plug literally pulled the filler apart.
Pretty cool.
