Surface Rust

[gander801]

started sanding and grinding truck and I am having trouble getting down to metal where there is a lot of surface rust. I am geting down to a black hard substance. where the paint is still there it is nice shiny metal any advice? Also I will be putting rustolum on while I finish this job. good idea or not? thanx.

I'm thinking that what you're running into is a glaze caused by sanding on the rust. If you use a slower (under 1000 RPM) machine with a more coarse (24 or 36) grit paper it will be easier to get to the metal. I wouldn't use Rustoleum if you're planning on painting later, you'd be better off either priming with epoxy primer or using Picklex 20 to stop flash rust until the vehicle is primed. Picklex can only be used if you're going to keep the truck indoors until it's primed.

I have used the rusty metal Rustolium on lots of minor things and it seemed to work really well. 2 years ago I blasted the bottom of my old Z 24 and didn't have anything better handy, didn't want to be spraying under the car on just jacks and blocks with a gun bla bla bla. Old car anyways so long story short I gave it the nice sprayed on coat of Rusty metal primer and them brushed a solid coat over that and followed with a quick coat of RUstolium Black. Old car so no real crime but DAMN. The rust was back by Christmas and I painted it in the summer. By spring it was evident popping out all over and I had blasted or wheeled it clean about as good as one could expect. Maby odd but that had to be the worst paint I ever touched. Lesson learned...............................:eek:

Gday! dont know how far you are planning on going with your project but i would be contacting a reputable sand/soda blaster! when you add up the cost of sand paper, power tool use and your own time nine times out of ten you are better off getting someone to blast the vehicle. you can also get chemical stripping done but i'm not a real big fan as all of your rust proofing that you can't get to inside door cavaties and around your wheelarches can be a real pain to re-seal. 3M and quite a few other companies make strip and clean wheels which are pretty much just a heavy duty schotchbrite pad that you use on the buff. hope i have been of some help.
