Thanks again.

I actually have a 6" random orbital polisher I picked up from walmart for about $15...I think its max speed is just under 3K. I had thought that this would be OK considering that Charger69 said he used the el cheapo units himself.

Before I do my car, I'd like to get the porter cable unit that everyone here talks about. I'm hoping to be able to finish my bike w/o doing so though.
