Media Blasting ?

[Jon Haigwood]

I have been experimenting with a media blaster I picked up at Harbor Freight. I wanted something that would assist in paint removal on paint fails. My first attempt was using baking soda on a relatively thinner paint, Candy2o over a rattle can silver flake. What little I did seemed to work but needs more testing. I just blasted a new unpainted Revell 3W and it didn't seem to harm the body but left a satin looking finish and I thought this may be a better surface for paint to grip than the smooth out of the box surface with out all the light pre-paint sanding. 

Anybody ever give this a try ?

I have only done tires using crushed glass and low pressure in my blasting cabinet to get rid of the sheen.

Man, that is some heavy artillery for a small styrene car body...

I mean I guess if you make sure to use the right material and keep the pressure/ distance/ and movement right it could work without texturing or blowing a hole through the body.

Seems not worth the effort/risk for me... but I'm interested to here your findings!

Just used baking baking soda at around 50 or less psi held 8" away. On the new body it mainly just took away the shine. On the painted body it took some of the paint off, down to the white primer, might be useful for a patina effect.

Some interesting possibilities.

That's kind of awsome not gonna lie! ?

Very interesting. I can think of a number of uses, but the effect on that purple body shows great potential for weathering, which I had never considered. 

Yes, very interesting indeed.

Judging by the looks of it, im gonna like the Harbor Freight price better...?... as usual ?

Using aluminum oxide with a small opening like that I can see it blowing thru the plastic. Maybe with baking powder at a distance it might work OK but then again $70 compared to $22 , will be going with the HF
