I've got a 70 Roadrunner convertible & I'm doing bodywork getting ready for paint. I have some rust areas where the top corners meet the body (left & right of Dutchman panel) and in the corners of the trunk drip rail channel.

1. I see corner repair patches at Goodmark, AMD & Sherman, but they appear to be for hardtops. Can I still use these as patches with some modification or what should I do?

2. I'm pretty sure the trunk channels are the same as hardtops. What should I use to patch these corners?

THANKS FOR YOUR ADVISE!
