finally got my truck back :) well 98% of my truck

[hawaiian808]

are we talking about the same stuff ? i mean like roll on rhino liner, i imagine after good prep and good weather/ paint booth it would seal and never rust? just like if it were in a truck bed, my pickup now has had it since 2004 and is still jet black and holding strong?

never heard of this... please elaborate

It get minor pinholes in it. Moisture gets in and is trapped. Since the undercoat bonds to itself so well, it does NOT flake off like paint. Then the rust is getting worse by the day, untill you put your foot thru the floor because you could not see the rust.

When i worked at the dealerships and I did undercoating on new vehicles, I wanted to cry

brad is right, rusty jones is a ****. lol had two vehicles so far that the undercoat was what was holding the carpet in.

so all i can do is prime it every summer? lol i plan on using it as a work truck ( i know i know) and during the winter i will be climbing mountains, literally climbing mountains haha , and all the rocks ill kick up i dont want to then hit hardball and get salt on it thus rusting my new floor pans etc out?

NOT prime.

PAINT the bottom of your floor with a good quality paint. Something with chip resistance. Then EVERY year if not twice a year power wash the bottom side of your truck and touch up as necessary

jee, thats gonna be expensive to paint the whole frame and under my cab etc , damn ,

almost as much to paint the body of my truck

Get a Harbor Freight paint gun and hook it up to an air compressor and go to town. I'd slather it.

Primer holds moisture, btw.

Single stage Commercial paint. Like Farm implement paint or rustolium, about 50 a gallon. And do NOT add hardener, it will stay softer and not chip as easy.

Automotive paint that you use on the top side of the truck chips VERY easy

If ya do this then you can justify having a spray gun... ant imo the harbor freight ones work damn good for what one pays, I've used them countless times and if thouroughly cleaned after every use(I mean clean them to the point they are completely spotless everytime) they will last a long time.

Definitely. Well worth the money, and they're cheap to begin!

Thanks Brad, I like this idea. Never really swayed towards undercoat, now I know why. Would a wire wheel and rust neutralizer be a good prep for this?

I wire wheeled and used Rustoleum's rust reformer/encapsulator (which primes the surface), then painted away.

Yes. But for the rusty spots I would use Eastwoods rust encapsulator, POR15, Chassis saver or the like as a "primer" then top coat with something soft
