When this idea popped into my head I had all kinds of aspirations. I wanted to make a template of the back seat, lay out curves, break all my wood working stuff, and go to town. But, in the end I thought, what good is a travel tip if Mom & Dad Q. Citizen don‘t have access to it. For that reason this is as simple as I could possibly make it.
Step 1: Prepare the plastics
Take the fittings and place them in the corners of the paint tray. With downward pressure rotate the fittings against the tray. This will lightly scratch in a circle. Use that mark as a guide when you rough up the tray side with the sand paper.
Step 2: Epoxy Putty
Wet a flat surface and roll the putty into a snake. With the fittings in place, press the putty into the corners between the tray and fittings. Keep your fingers wet.
Set the tray aside and let it cure.
