Big rusted crowbar & huge ballpeen hammer

[Veloce_Racing]

OK, these are the two tools I plan to use tomorrow to change the rail trim on my Ascent i's UNLESS one you people tells me of a better way. If you don't then I can't be held responsible for what happens tomorrow. Give a chimp a gun ... the chimp shoots someone ... you can't blame the chimp. The clock is tickin' ....

I would recommend a hammer drill with a 1" bit. That ought to do it.
Your other options would be a skill saw or angle grinder.

If for some strange reason you still want them to look good enough for resale you could try this as a last resort:
