Rust problems on sliders/bumper

Spray a little wd40 on a brush and brush it on the surface rust.

 

So what kind of sand should I get for the sand blasting, and how much do you think I'll need to get?

 

Wouldn't that be like putting "greaser" on it, instead of degreaser?

 

In the short term, coating surface rust with solvent like wd-40 will slow the advancement of the rust. But, it will wash off (roadspray in the rain), and won't provide protection in the long term.

The degreaser I mentioned earlier is really part of the prep process. Unless the surface is clean of debris and grease, the primer/paint won't adhere well. The better the prep, the petter the results.

 

Thank you for your service.

 

I’m not saying to cake it in oil but rub in some oil on the surface to prevent rust from forming.

 

Thanks mate, that's kind of you to say.

 

I appreciate anyone that volunteers to serve our country. Not trying to be political, but I wish everything could go back to normal instead of people hating on each other over differences of opinion.

 

And we'll leave it at that.

 

We used to purchase #30 mesh sandblasting sand in 50lb sacks by the pallet. The brand was Monterey Sand Co. IIRC

We used an industrial size sandblaster, used replaceable ceramic tips and wore out the ball shutoff valve regularly. I would protect nearby surfaces with tape etc when you blast.

 

Perfect, honestly I'm only using it for a couple jobs, could I get away with a 10 or 20lb bag?

 

So I've been looking into using my VAIR 450P air compressor for as a sand blaster. But it looks like the CFM might not be up to the task. It's 1.8CFM and the sand blasters all say they work at about 20CFM at a minimum...any way around this? Or am I SOL...this project is becoming expensive quick...
