Need some Suggestions/help

[Danger-Ranger96]

Hey guys, seeings how i've been doing alot of work on my truck lately, i've decided i'd like to spray my bumpers with bedliner, the shit you can buy at automotive shops. A friend of mine told me to buy actual bedliner spray and not just Rockerguard protector, He told me that it will never fully dry and will fade into a gross purple color. Anyways, with that being said, i've already sanded the front bumper of my truck a bit to get most of the rust off it. Now i have an idea to do up to my body line on my truck with the bedliner too. RWARanger Has his DD done like this, and my truck is pretty close to the same color as his, maybe a little lighter. I guess what i want to know is, if i go about doing this, what would be the best way to do the rockerpanels (up to the body line). I'm thinking of taking lots of newspaper and masking tape to the whole side of the truck and just go hard? or should i take precautions. RWA if you read this thread, could you give me some feedback on how you did your truck with it? I think it looks awesome and it would help the little bit of rust i have forming at the bottom of my doors to cover it up. Before i do the actual spraying i'm going to rough it up with 75 or 80 grit sandpaper as well just so i'm down to bare metal (this being the little rust spots), That bedliner stuff should just stick to paint right?

Anyways here's RWARanger's DD:

And this is my rig:

Did you do your paint plan yet?

I did it on my 99' Dakota, I had surface rust behind the rear tires so I used a 5" grinder and a wire wheel to clean down to the metal, then I sanded the crap out of it. I then picked the body line and used masking tape and newspaper to shield the top of my truck and then I did it!! effort has to be made to the paint line even between the cab and the box. I can email you pics if you want, PM your email addy.

I used some stuff from Canadian tire, ? $5-8 a can i think? I did it in may. I don't have running boards and live on gravel roads and so far it is holding up to the rocks very very well.
