Has anyone used a Badger abrasive gun for prepping plastic or metal for painting? The 220 Aluminum Oxide grit seems a bit harsh for plastic prep.

I bet that will take Kato paint off fast. I knew there had to be a better way. Glenn

I have had one of those for years and could never get it to work for more than a few seconds before it would clog up. I tried everything to get it to work properly, but never it did. It now sits buried in the bottom of the supply closet.
I even tried a big shop compressor and the thing wouldn't work.

I have the badger one and I use it to strip paint all the time. the only problem I have with mine is that bottle is too small so you have to fill it up all the time. Mine clogs up quite a bit but thats because of all the dog hair that mixes with my baking soda.
One thing that it does really well is give handrails some grit so you can paint them and they don't chip.

I use a Paasche AEX (the one with the large paint sprayer bottle to hold the abrasive). Keep your air pressure at 40 to 50psi in order to push material through the tip without clogging. Baking soda or pumice does good at 40psi, but aluminum oxide needs 45psi or higher. Also, high humidity plays havoc with any abrasive, so pick a dry day to blast away. This technique is really good for prepping delrin for painting.

Call me stupid, but are you guys using your airbrushes to shoot baking soda and other media through to blast engines? If so I never though about doing that before. YOu learn something everyday. Glenn

H-mmmm, not really sure about the other fellows, but the Paasche AE I use is a specialized animal, equipped with a carbide tip, designed for air (grit) blasting, but not for spraying paint. Would really like to see how to use a regular air brush for such a chore, seeing as how I got a couple of them lying around idle and gathering dust.

Glenn No, I use a gun made to blast. I think if you were to use an actual airbrush, you wouldn't get enough medium to get the job done very well. Might be worth a try. This is what the badger gun looks like. www.dickblick.com/products/badger-mini-sandblasting-kit/-Andrew |
