I never realized what a work of art some of these restored cars are until we started blasting them.  It’s very easy to take for granted the amount of craftsmanship and work that these guys do to make these classics so beautiful.  There is a growing appreciation for those who can blast, cut, patch, weld, bondo, bolt and paint these back to life.

This particular job was a VW bus which belongs to our company’s mechanic, Bryan at Cook’s Tire and Tune in Fullerton CA.  He referred us to his guy Matt who does body work.  This VW would normally get blasted by Matt’s media blaster, but when he saw it he said he didn’t want to touch this project. 

Here’s why:

This undercoating was so thick and it had a rubbery feel to it that the dry blaster said it would just get gummy and wouldn’t cut through it.  Why you ask?  Because dry blasting gets so hot due to the compressed air and friction of the dry abrasive on the surface that on many coatings it just clogs.  One of the key advantages of our dustless blaster is that we can cut through these coatings because the moisture vapor that shoots out with the media and compressed air actually cool the surface.  When the blast area temperature is ~ 10 degrees cooler than ambient temperature (as it is with the dustless blaster) you get results like these:
Our customer saw a thirty second demo and was so impressed how our blaster cut down to bare metal that we secured the job.   Here’s another pic for your viewing pleasure…
Dustless blasting isn’t a perfect process though.  It’s still messy (just not dusty) so we need ample room to lay plastic down to catch the abrasive that falls to the ground and ricochets off of the surface.  The best way to describe the mess is imagine throwing a handful of wet sand against a surface vs throwing a handful of dry sand.  Both are a messy process, it’s just the wet sand will be a lot less dustier as it will want to fall to the ground.
Additionally, one of the big things to consider is that you only have about 1-3 days to get primer on the car after blasting because blasting steel surfaces with water will cause it to flash rust.  Although we use an additive called hold tight 102 which prevents flash rust for up to 72 hours, the rust can still return quickly especially if you don’t store the car indoors after blasting.
Finally, it’s a loud process.  Notice we use ear muffs all the time.  So forgive me now if you call in and ask for a quote and I say, “What’s that you ask? I couldn’t hear you?”  Oh well, maybe one day we will create a way to communicate by sending digital messages on our phones and computers.
