Well I got this 68 coupe its got lots of rusty spots in side so i got this little 10gal media blaster it dont seam so strong but it works ok. now im reading in paint an body that i better know what im doing or it will warp the metal you think this little machine will do that help me out guys

If it's a siphon feed, or gravity feed...it will do it, but you will be there forever and if you use sand and are not experienced...you do run the risk of warping the metal, especially in long flat areas on the body.
A lot of people are using crushed walnut shells to blast bodies...but even at that you really need a pressurized blaster and experience, or practice. Most of the warping will occur from holding the nozzle at 90 degrees...this angle builds up too much heat...the metal needs to be hit at a nice gentle angle, and even at that you don't need to stay in one place too long.

I use a 40lbs pressurized baster from Harbor Frieght and it works great. But, you also need a good size compressor with enough CFM. My compressor is an 80 gallon and has 21CFM so it keeps up with the blaster no problem. I use both sand and glass bead depending upon what I am blasting. I use the glass bead for the large flat area (just in case), for the rest of the car I use play sand. I have been able to reuse the sand a couple of times, but be careful because the silica is harmful when breathed, so wear a dust mask.

Thanks Steve you got some realy nice cars there hope mine turns out as well Richard

Thanks Rally Sport you know the worst of the rust is on the inside the out side sheet metal is not so bad. So maybe i will use another method for the outside Richard

As far as a cheap useable blaster...I have heard good things about the Harbor Freight unit. The only disadvantage I see it has, as compared to some of the higher dollar blasters, is the way it fills, but this is no big deal to the hobbyist.

I don't think a dust mask is sufficient. You need to get a good respirator.

I agree, a good fresh air breathing system, that pushes air from the outside into a mask or a helmet is the best setup. Hobbyair and many others sell these systems, or you might be able to rent one locally.

Best of luck with your rust problem there! Ditto on the heat and warping related to sand Blasting, be careful!
I have been kicking back and forth the idea of starting of a Plastic Media Blasting facility for doing exactly what you describe, for the last 11 years now, although it doesn't work on rust, it does strip a car in as little as two hours!
Have any of you guys ever had a car media blasted, and if so, how much did it cost to have this done?
The equipment is rather pricey and a lot of thinking has to go into a project of this size, but it's a good service for the automotive restorer as well as body shops.
It saves time and money in labor and materials. I once restored a '69 Camaro that had, I would say, ten different coats of primers and paints along it's lifetime, after $400 in sanding materials, I would have been better off media blasting it!
I plan to open this business up in Missouri, anyone out there think this is a good Venture to pursue? I will be doing this outside the city limits to limit the air quality issues most businesses might have to deal with, I know some cities won't even let you start an air compressor without an air quality survey done first! Guess we will see where this goes.
Have a good one!
