Hello All,
Trying to get prepared to finish all of the reinforcement work on the body and decided that it would be a good idea to do a little sand blasting to clean things up a bit. I've seen units from $199 - $3000. And visually can't see any difference in them. I've seen blast media from sand to walnut shells to soda. Can somebody that has used these on a car tell me what is the best buy for a poor homeowner that wants to have a unit to use more than once but doesn't want to spend the motherlode. and the best overall media. Any help would be appreciated. Off to ball practicefor my kids. Be back to look at this in a bit. Thanks. |

Sandblasting parts is OK, however, if you're thinking about blasting the chassis, i recommend you read the thread in my signature.
It contains some info on why i would never, ever sandblast a chassis again. Ever. (IMG:style_emoticons/default/stirthepot.gif) Andy |

I didn't have to with my 914, but I know guys in the muscle car world who are still finding sand in their cars 3+ years later |

Sand removes metal. Glass bead removes rust only and not metal. I don't really know about the others.
And it gets everywhere (all of them) ... even places you can't see or clean. |

Also investigate soda blasting. Eastwood has a soda blasting kit or attachment.

If you are going to sandblast things for many years to come, invest in a pressurized system, NOT a syphon feed.
If you are only planning to do one car, RENT the equipment. You can rent a very large system that would cost thousands...and use it for the weekend. One other option is to hire it out. There are many places that will sandblast your car for you...again, its a one shot deal. Rich |

Its water soluable....so afterwards, just hose off the driveway or wait for the next rain storm and its gone. Its softer than sand so it wont heat up the larger panels and risk warping them. it is great stuff |

soda blast is great,,,had my car done,,,doest hurt wireing trim etc, and promotes a protection to the metal against flash rust. The big but is you need to acid wash the car after so the paint will stick!!!! Metal prep, or a vingar mix something.. My guy gave me a wash for the car.. The other but is that it will not get rid of rust,,,just paint...

I have tried lots of low end blasting and nothing seems to actually work well. The big problem (other than the ones already mentioned) is moisture. If you live in a humid environment and you do not have an air drier and a good compressed then you will only get frustraited. As much as I would like for it to be otherwise blasting is more complicated than it seems.

I use a short whip hose connected to a last chance water trap (with another water trap attached to my pressure tank where the main hose comes out), and I still can only sandblast for a while in this humid east coast weather. I don't own a sandblaster; I borrowed a siphon blaster. Never used the pressure blaster but all sources indicate that it is a much better tool than a siphon blaster. |

Lots of good info here. I read Sir Andys thread and looking at the photos sandblasting is OUT! I do live in Alabama so mosture will be a problem with soda. I will have to get a good system for drying the air to go that method. I will be able to sand the car for the most part. It is mostley rust free with exception to some small areas. The hell hole even looks great. The main thing I was thing about was getting the shoots off the under side and the excess blobs of seam sealer so I can clean this area up also. I bought Armondo Serono's rotisserie and want to do it right. Paid a hell of a lot of money for it but if the two cars that I am going to do turn out really nice it will be worth it.
OK.... Let me redirect.. What is the best method for cleaning off the shoots and seam sealer? |

Professional soda blasting is the way to go. Doesn't hurt glass or trim and leaves the base metal clean and free of paint.

Good to hear from you Perry. Finally going to get started getting the flares on and want to start with a clean undercarage. The car has no wheels so moving it will not be easy. I would like to do it here if possible.What do you think is the best one out there that is in a poor boy buget.
If you like we can fog up the pole barn like a flour mill (IMG:style_emoticons/default/w00t.gif) |

I have cheap siphon and pressure blasters. Siphon tend to clog up more, which is the big pain about blasting. You need to sift the media well so no big chunks get in there and cause a clog. It is a hassle stopping and taking everything apart to clear it out. With a pressure pot blaster I always turn off the flow of media before shuttng the blast nozzle, otherwise it causes a clog. I ran a 10 foot line from my compressor to a $50 water separator, then a 50 foot line to my blaster. The air coming out of your compressor is too hot for the water separator to work well unless you run an extra line to let it cool. My pressure pot blaster has a second water separator right before the tank. Right before the blaster I use a disposable water remover cartridge that turns red as it absorbs water. This is enough to make things work ok in FL, so it ought to work other places. Using a clear tube from your siphon blaster to your media helps to see when a clog is forming. When everything is working well blasting is fun for about 5 minutes, then you realized how slow a process it is. It is like cleaning your parts with a toothbrush size area that you have to move slowly to get everything off. Doing a whole car with a cheezy set up would be a real nightmare. I think it is best for small parts with complex shapes or parts of your car that are impossible to reach with a wire wheel or grinder. John |

Soda blasting... Have it professionally done. Seam sealer must be picked and scrapped out. Rust will have to be spot blasted with sand or cut out and patched.

Jimmy, shop around and see if anyone in B'ham does soda blasting. They'll bring their rig and be done in hours, and you'd be on to the next thing.
I've used two cheap Sam's Club furniture dollies for moving a bare chassis. If you've still got suspension on the chassis though, you'll need hevier duty dollies. |

Perry, Just returned from a shop close by that will do it for 600.00 or so and prime for an additional 300.00 for a 900.00 total for the undercarage. How does that sound for a price?
Conedodger, I believe you are right ole boy. |
