Should I dry sand paint off or wet sand it off? I'm just doing my hood, nothing real major. I have access to a dremel which I'll use insted of sanding.

Thoughts?

Wet sanding is for polishing the fine scratches out when you're going for a mirror gloss surface. The entire process is explained very well on many web sites that are tutorials for detailing. Many of them put up by the mfrs of the products involved.

Edit: You sure you're an offroader? :confused:

Ok, A Dremel with a grinding head should work, right? Gotta Love Michigan Rust! :hahano:

Only if you strike out with dry sandpapering. Grinding wheels clog up with paint. Make sure you have all the rust prevention and priming products you're going to need BEFORE you expose bare metal. Again, LOTS of web sites explain the process of fixing automotive rust areas. That's a hint. :wink:

Using something like a nylon impregnated paint/rust removal attachment for a handheld drill is a good way to get rid of rust without much effort or damage. After that, hand sanding or using an orbital palm sander will get your surface ready for body filler/primer/paint. I am not sure what kind of work you are doing or how you plan to finish it, but keep in mind that if you are looking for a finished repair that doesn't look like a repair you are going to use a finish glaze at the very least. Removing the rust WILL create an uneven surface.

What I plan on doing is removing the paint with the Dremel and sand paper. Brush some Ospho on it(to stop the rust). Then hit it with Krylon Dual Paint and Primer(few coats) and call it good.
