Sand blasting is quick and easy but very as nasty, i would recommend against it, sand will get trapped in small gaps and collect water which will then rust really quick. I don't know anything and haven't heard anything bad about bead blasting, which could be good. |

There are lots of ways to strip paint off a car. Blasting is perfectly fine as long as you are not silly enough to use sand. (nobody uses sand  ) The professionals use garnet or steel grit on heavy stuff, plastic grit or glass for finer stuff and soda for very fine stuff.
My local bloke will use plastic grit on cars as he does not like soda getting into folds and seams. A good blaster can blast aluminum panels without warping them. 
A bad blaster can warp steel panels in seconds.
Paint stripper is a very good way to get paint off as long as you use the right technique. Look for the thread by Brown Clubman about his paint stripping efforts. It is the way I will be doing my LS shortly.

My car will be plastic bead blasted in the next 6 weeks. It will be the third car I have done this to, and if there is a fourth, then it will be blasted as well. Plastic bead polishes the metal as it removes the paint, and does not take any of the parent material away (except the oxide). It will be primered in one step after that and the rest is up to you. No nasty surprises, no old repairs lurking under left over bog and no downsides that I have experienced (apart from being able to still find the odd bead of inert plastic a couple of years down the track hidden in a deep dark corner...). Acid bathing..well that's another matter, and sand blasting, that's another one as well.... |

I got a quote only a week ago for 750 dollars, inside and out, sill to sill including doors and boot. |

Last week when I was in Mackay I met a bloke who has the Aust/NZ rights to a new kind of blasting. It uses Dry Ice and abrasive. The abrasive is only 10% of what would have normally used. The dry ice once hits the panel vaporises leaving nothing behind. Enviromentally frendly too. Looks to be the new thing. |

(Unless he plants a tree.  )

I've got an idea the use of environmentally friendly abrasives (like soda blasting) are of interest only to operators who do a lot of work outside, like blasting bridges, industrial equipment etc. The use of soda means the stuff can be washed away with a hose instead of collected and shovelled into a trailer. Probably conforms a little more nicely to council environmental bylaws as well if you run your business. Less cleanup costs, less guidelines to conform to, less inspections and complaints and the customer pays for it. Soda is 1400 dollars a ton. Garnet is about half that in cost. I mean, what's the environmental part of the deal here anyay? I mean we're blasting off paints, primers, bog, lead paint and iron oxides... |
