blasting
I have done a good bit of blasting myself. There are many issues. Power of machine, size aggregate or abrasive, person who is doing the work, and the thickness of the product you are blasting. I think the metal on my 68 912 is really thick, which is good. For me, good old sand blast sand works well and is cheap. There are tons of options and I am no expert. The blasting I will be doing in the trunk is for getting into the cracks and crevices that a grinder could never reach. IMO, if you don't do this, you are not doing it right. I am not familiar with dipping so I cannot comment on what it does to rust. After I blast, I use compressed air, shop vac and a back pack blower to get the sand dust off the car before bringing it back into the shop. But the sand does seem to keep coming out for a while, but by the time I am finished with metal work it is gone. IMO, do it once and do it right. That is why I sand blast. Oh and always use personal protection devices. Especially a respirator.
Another product that I have found works really well at stripping paint fast in large areas with no damage is the Norton Rapid Strip Wheel/Disc. item #04015. Or similar product. But this one seems to work better than others I have used. It attaches to a 4.5" angle grinder and makes quick work of the paint and surface rust. Buy many of them bc they work well, stay away from sharp edges of the metal as it will shorten the life of the disc.
