Default Painting the under carriage...?

Hey guys- been awile since i posted on here. I DO have some new mods but the truck hasnt been clean enough to take any pics.
Anyway, i am planning on painting the frame and axels before winter- i plan on parking the truck this winter so it will be safe from the salt. With the BL i can see more of the under carriage and would like to get it cleaned up a little. How should I go about this? should i scuff up the rusted spots and just paint them? Or should I scuff everything and paint it? I dont want to strip the whole frame down because thats too much work . Anyone have any input/ideas on how to go about this?
Also, any suggestions on what kind of paint i should use? I know a lot of the rubbery undercoatings just peel and flake off, I want this to last...

Thanks guys

best stuff to use would be POR-15..its pricey up here in alberta canada about 60 bucks a quart but its wicked stuff and tough!.. I believe you just wash the surfaces with a pressure washer, and wire brush and flakey rust off and then just brush on.
Not sure what it costs down in the states. and trust me this stuff will last!

I just use the undercoating you buy at O'Reillys etc. It' maybe $5 a can. It's a spray can about the size of the cans of spray paint you buy. I've used it for a few years and it holds up well.. Secret is to put thin coats on instead of caking it on. My Ram was beginning to rust up underneath and this stuff has lasted over a year so far. I think I might have used 3 cans to do the suspension, drive shaft rear end etc.

I Used Eastwood's Rubberized undercoating. Stuff works great. Just clean the surface and any rust and spray. Much easier to apply than POR15. I've done both. The surface must be prepped really well for that stuff to stick properly and it stains everything. HERE is the Eastwood stuff. Holds up pretty good against rock chips, but will needed to be recoated every 2 years i would say.
If you have a bit of rust, you could scuff it down and spray on an asphalt based undercoating. That will penetrate the rust and stop it from getting worse without primering and coating over that and all that stuff.

how does the eastwoods rubberized stuff hold up to salt? up here in canada they're big on putting salt down in the summer..and then the salty air on the coasts are nasty too. thats why im fond of por15...and i dont find it takes a lot of prep work when its gonna put years on your trucks frame lol.

This is what I use. It holds up and looks great! Take a red scotch brite and lightly scuff/knock the dirt off. Hose it down, and when it's dry spray bomb away.

Frog- Do you do a lot of tapping? Or just spray around stuff? That looks good!
