Soda blasting - any good?
« on: May 04, 2014, 09:54:23 pm »
Just watched Edd China of Wheeler Dealers totally restore a beaten-up rustbucket with extremely fragile panels by blasting them with a mixture of sodium bicarbonate and pixie dust before restoring a nice mirror finish. The thing that impressed me was that unlike glass bead blasting there was no metal loss and the process actively helps the steel surface against rust. This could be a revelation for thin walled bicycle tubes?

Anyone had any experience of this?

Done a few car and bike panels...it is messy.  The coating lasts about 3 weeks.

I always thought the usual alternative to sand blasting for delicate stuff was ground walnut shells.

I know that the heat generated by the blast media hitting the panel is the issue.

Ah well, "Black Bess" is off to Finesse Coatings tomorrow for a good dose of powder coating preceded by glass bead blasting and acid dip.
