dustless blasting

#2
if I where to use dustless blasting does the stop rust chemical have an effect on epoxy primer?
I used to own a dust less blaster did prob 6 cars washed them off with solution with no problem all the hold tite does is remove (neutralize) salt which is what causes rust from the water I would still pre clean exterior surfaces but on interior floor pans etc I blew off and epoxied and I checked adhesion and it was fine

I think biggest issue I heard of so far is warping, which is user error. Also a mess to clean out areas such as trunks that may fill with wet muck. One person here did have some pitts that were rusting after . Hitting with a soft rotary wire brush helped that problem.

Did you have a problem with packing media in the seams inside the car, making it difficult to remove?

Why did you get rid off the blaster? Do you not recommend purchasing one?

using water will not prevent warping the metal . period.
yes, the water does one thing only and that is control the dust. sheet metal doesn't warp from heat. it warps from the media stretching the panel. its like 1000's of little body hammers beating the metal. I had someone come out and blast something for me with a dustless system. what a mess. there is really no reason to go the wet route unless your blasting a car in a neighborhood and the dust will cause issues.

Like Jim and shine said warping metal with a blaster has nothing to do with heat it has everything to do with the operator they do a good job of selling them on the heat tho I do think they did a quicker job with the water but oh man what a mess I'd rather have dust than mud so I guess I'm saying no I wouldn't buy one unless you are in an area where dust matters

you judge media by the MOH scale nothing else. makes no difference how it is delivered. air pressure is all that will effect it. even soda has a 2.5 moh. shatter is all that keeps it from warping metal. but dont believe for a min it wont harm fiberglass.
