DRamrod, if the rust is not any worse than the photos posted by others on this thread, I wouldn't worry about sanding any of the rust.
1. Make sure it's clean of dirt, excessive road tar, etc....
2. Make SURE it's DRY.
3. Make SURE it's DRY.
4. Make sure the temp is around 68 degree or higher (you don't want super tiny bubbles forming - depending on how close you spray and how heavy). Also, BE PATIENT!!!! Wait until spring if you have to. I promise you that the underside of your truck will not crumble between now and then.)
5. Make SURE it's DRY.
6. If you don't have a garage, then buy a six pack of beer for your buddy that does have a garage and tell him how he's your best friend for allowing you to use his garage.
7. If you don't have a best friend, er... I mean access to a garage, then place jack stands under your truck and remove both back wheels.
8. Steps 6 & 7 are dependent on whether or not it's windy and how much time you want to spend GENTLY cleaning off the wind blown over spray from your aluminum rims (It was a big pain in the rear).
Okay, these next few steps seem silly, but for those of you that have rushed in to something followed by regret, you'll appreciate this:
9. Crawl under your truck with a good light source and see if there is anything the paint might land on or over spray on to (under body sheet metal, muffler, yolk, joints) and ask your self if you can live with spray over on these parts.
10. Before spraying, check your nozzle.
11. Be patient and spray one light coat on everything you want painted.
12. START WITH AN AREA THAT IS NOT SO EASY TO SEE ON A DAILY BASIS, so if you screw up, it's not so easy to see on a daily basis.
13. Repeat step 11. Depending on the temperature and humidity, you don't have to wait until the paint is completely dry before applying another coat.
14. Humidity and temp can play a factor. I grew up in west Texas where the air was like holding your face close to the opening of an oven door (dry and hot). Now I live in the Dallas / Fort Worth area, where it is insanely humid.
Plain Rustoleum spray paint worked fine for me 17 years ago on my old truck. As mentioned above by another member, Rustoleum makes a paint that actually stops rust dead in it's tracks. I did not know this and I would recommend it's use.
I really hope this helps and good luck! Post pics
