Thanks Mat Mobile, your van looks great, really like the old school vans I grew up in them dad was a van nut. Thunderstorms set me back last night, called it quits around 9:30pm to keep peace with the neighbors. Just found out I have to go out of town for work so this project will go into next week. I was concerned over leaving some of the bare metal exposed but not sure if it matters? Using POR 15 I would be prepping the metal and applying over rust anyway.
My method so far for removing the sealer:
Working in 8"-12" sections:
Apply heat to the sealer with a heat gun on highest setting.
Using a 1/4 inch chisel and a hammer, pry the sealer away from the roof side first.
With 1/4 inch chisel and hammer, pry the sealer out along the length of the gutter, angle the chisel to get as much sealer out from the inside lip of the rain gutter.
Use a wire wheel/drill to clean up residual sealer, follow up with a 3M rust paint stripper wheel.
Remove the fine particles with a pick tool.
Takes about 10-15 minutes per section.
Will continue to update as I move forward, maybe this will help someone on the fence about the project.
Mike
