Stripping paint and prepping car for paint

I recently stripped my 1970 Challenger, to bare metal. I used a 30.00 Harbor Freight grinder, about 25 bucks in their velcro sand paper, and 8 hours, to strip 95% of the car to bare metal. I followed with lacquer primer (going in garage, not weather proof). I added a set of "mickey mouse" ear protectors and safety glasses.

The chemical stripper works, but has a lot of handling characteristics that need to be addressed. The sand method works very well, and only took a day and roughly 50.00 in supplies and equipment.
