Sandblasting

Post by Stomper on Mon Feb 05, 2018 6:44 pm

I was told by a vintage vehicle restorer not to sandblast my van, as it will warp the sheet metal. Thoughts?

Sand blasting creates heat,that's what warps the metal. A friend had his 65 GMC soda blasted.

You can use one on the rigid areas. Like by drip rails and hard curves. Just stay away from big flat areas.

Find someone in your area that does Dustless Blasting. They're awesome. Fast paint and old bondo removal and no chance of warping. Usually around an hour to completely strip a vehicle. And they add a rust inhibitor to the water that gives you 72 hours to get an epoxy primer on to protect the bare metal.

Some of the stuff I sand blasted. As a DIY'er I used chemical stipper, paper and a bunch of 2" scotch pads also.

best to sand or other abrasive blast only the bottom and around the hard to sand areas like the window frames and door jams. Then use a DP sander with about 80 or 100 grit and sand the paint off the flat areas. if the paint is old it will sand off easier than one might think. in fact mine with original sun faded paint sanded to the steel faster than you could sand blast it.

On a semi-related note, how are the roof support rails attached to the roof? The roof in my van is pretty much completely separated from the supports (and rattle like crazy). Is there a fool-proof strategy for reattaching them?

I don't think want the rails to attach to the roof. The sun beating down on it will cause it to expand. If it was spot welded it would buckle and warp. On mine I took a strips of plastic and shoved them between the ribs and roof to stop the rattle.

3m has a product that is called fast and firm it is a
seam sealer in a caulking gun tube, I used this product
between all the ribs and outer skin in my van, stopped all
the rattles, it is not meant to glue it togeather just stop the
vibration of both metals.
