Sandblasting is ineffective against scale. It worked great in my dually, but it wasn't MI rusted.

Ill take the needle scaler to it first but I just wasnt sure what would be a good undercoat for a bed. I mean I guess I could just por15 it all

Started sandblasting today. Boy it takes some time to get anything done with a 26 gallon compressor and sand blaster. Anyone know if I have to get every little spot blasted down before I self etching primer it? Or will the etch be okay? Or do I say **** it and por15 it?

Anyone know if I can get away cutting an inch down on this guy that has a rust hole through it?

It looks like the underside of part of a box.

Sandblasted then self etching primed and now Rust-Oleum top coated the bed today. Curious how long I should wait to spray rubberized undercoat? I'm thinking I'm gonna give it an hour.

I think the dry time is 24 hours. You can recoat within 1 hour OR after 48 hours.

Okay that's what it said on the can. I just wasnt sure if rubberized spray was in that category

I'm no expert BUT, if it was me I would wait as long as possible for the paint to dry before undercoating. That way most if not all of the solvents will evaporate out of the paint. A rule of thumb I have used is 30 days. Probably overkill but I would rather wait then possibly have drying issues.
just my 2¢.
