I've just had my '52 Chev cab (inside and out), frame running boards, driveshaft and steering column blasted. I'd say the jury is still out on it. I'm not sure if it's the product that we want for these old girls. Where there was good solid paint it did wonders, nice shiney metal. Where there was rust, the loose stuff is gone. I'd say the whole thing now is a candidate for ZR except that there is a film on the whole thing that is apparently best removed with a mild solution of vinegar and water. I'm told that paint/primer will not adhere to the film that is existing. Anyone else tried this stuff?
