Ok, I'm game. So what media, and where to buy it?

Also, I know why soda blasting residue is bad, the paint won't adhere. But I've blasted with sand many times, no problems ( yes, I do use a respirator ) but what is the problem with silica on the steel?

...... but what is the problem with silica on the steel?

All I know is what I've read here, and I think that Shine has provided the best advice over time. I'm pretty sure that he promotes using plastic media, which comes in different sizes (and hardness?), but I don't recall a source being listed. I've seen 5 gallon buckets of plastic media at the Northern Tool outlet, but again I'm not a blaster, don't own the equipment, and have zero experience with it. The stuff sold by Northern Tool may be pure junk - I Do Not Know, get good advice from someone with experience.

Silicosis is one of the biggest issues with using sand, and the residual dust gets everywhere and can be breathed in later, as someone/something disturbs it, like using a compressed air jet to get rid of dust - something we all do without thinking about the source of the "dust". On the surface, silica is a natural form of silicon that’s been slightly oxidized through exposure to oxygen, which forms silicon dioxide (Si02). Residual silica can also cause adhesion problems, as I understand.
