IMHO, the project is far too labor intensive to ever recover your
labor costs, much less material costs, unless you are willing to
work for $3-$4/hr.

As far as sand blasting is concerned, you ONLY do it outside
in the drive way.

Might try to reclaim sand for a 2nd pass if you can.

Even garnet is an expensive blasting material and you want to
seal the metal as soon as it is blasted clean.

This project could become a bottomless pit in a hurry.

Just my opinion.

Had a guy down the street who did glass bead blasting.

Made him a deal.

If he didn't build boats, I wouldn't blast clean things.
