I did quite a bit of heavy rust removal on my mustang project. Now I'm starting to slowly work on my model A project which is even worse. The surface is rough, but after sanding or sandblasting, it smoothes out pretty good, but the there are a lot of large pits.

When I did the mustang, I had to use 40 grit to get rid of the rust and paint, then I went over it with 80 grit and naval jelly. I did a test area on hte model A sandblasting, but it's slow and uses a lot of material.

Is there another product I can use to strip down to bare mental? I could go over it with naval jelly once it cleaned up. I've never tried those stripping disks, will they work on heavy rust?

Some different strategies to try is to use the disk to get the surface rust and then spot blast..You may need to try several different media to find one that works well..another thing to condsider is using electrolysis to remove the rust..that works quite well in practice..just need a large tub to fit a fender in..

Be careful about grinding as that can thin the metal too much and ruin a part..

Just my take on this one

I picked up one of those 3M stripping disks (these a couple theads on them right now) and tested it. Works pretty good, but still kind of slow, but that was with a wimpy battery drill. Need to find some to fit my 4-1/2" angle grinder.

BTW, need a pretty big tub to fit the whole body in. Ha Ha

Arrowhead, are you using a pressure blaster? or a siphon type?
I have found my pressure blaster works much faster and uses a lot less sand than the siphon types I have used. The sand flow valve at the bottom of the tank should only be open around half way....at least on the blasters I have used.
