Out near Bull Run Mtn there is a guy who does nothing but sand blasting.
Reasonable rates and does a great job.
His contact info:
kenny o'day of all-blast. he's off route 15 on bull run mtn. 703-754-3316
Also -
American Stripping in Manassas does all kinds of blasting, including plastic media - the only thing they don't do is the newest coolest thing - dry ice pellet blasting, if anyone knows of someone who does this, let me know ASAP, closest place I've found is NC and PA. I need to get all of the undercoating off my father in laws 356 and the stuff has asbestos in it (as does all old undercoating).
American does a great job, but they are not cheap.
If you do it DIY, I don't know for sure, but I have heard the CARC paint on those things is super toxic - even in the sanding or sand blasting. Again, this could be total BS but that is what i've heard. I do know that it's basically just automotive paint with a few additives and these chemicals are what's supposed to be nasty. Again, not sure, just hearsay.
Let us know who did a good job, always handy info.
