I stripped thirty years and three layers of paint off of my 70 Mach1 by using both chemical and media blasting. I used a pressurized blaster that I bought from TIP (around $350 at the time) and did all the body componetnts that could be removed,hood,doors,valances etc. I used chemical stripper on the roof,rockers etc..only because the body was apart and on jack stands. Chemical is work,but it does the job.However you must be certain to remove all the remaining stripper to prevent problems with the primers in the future. The stripper problems are in the pinch welds and other nooks.
Good luck
