DIY Rust Preventative-PB Blaster?

[sgg93]

I was pondering a cheap way to keep the truck rust free this winter, and I was wondering if it would work just to pressure wash everything underneath really well, then get a gallon of PB Blaster and spray everything down. Insides of body panels, frame rails, all of that. Anybody done it before?

May want to check this stuff out, made for exactly what you want to do. I have no personal experience with it, but thought I would suggest it. http://www.fluid-film.com/

My wife has done PB-Blaster on some parts, Fluid Film on others. Pretty happy with both, but I'll have to check-in with her about specific results.

The PB blaster washes right off. The Fluid Film or the like is what you would want if you want to retreat Every year and dont want paint to stick to it.

Personally, I like POR15

Por15 is great. rust-inhibiting rustoleum primer is good too. then put undercoating over it.

friend of mine has bought a couple truck brand new and swears by 30w motor oil. puts it in one of those hand pump oiler things. seems to work pretty good. his 95 doesnt have much rust on it

Thats the ghettto, cheap way of doing. Do it once, do it right. User the proper liquid and undercoating.

PB Blaster is the wrong tool for that job

Living a few hundred meters from the Gulf of Mexico, you learn how to deal with rust quickly. The following is jsut my $0.02, take it for what it's worth.

There's a few ways you can go about it (these are just my opnions):
To neutralize your rust:

Good: Go to your nearest ACE Hardward and buy a gallon of Oshpo and a few plastic spray bottles.

Better: Go to your nearest Home Depot and buy a gallon of Rust Bullet and all associated application products:
Rust Inhibitor Paint | Stop Rust | Rust Corrosion Inhibitor | Rust Converter

Best: Go to the link and buy the rust Prevention.inhibitor from Eastwood.
Rust Repair - Auto Body Rust Treatment - Corrosion Treatment - Eastwood

Take a STOUT wire brush and knock off all the rust you can get to. Doesnt have to be perfect, jsut get the flakes off. Pressure wash the underside of your rig, mask the driveshaft, U Joints, exhaust, fuel lines,sensors, etc and start spraying everything metal. You can also use a cheap paint brush to spread it around for better coverage.

Then, you can apply a top coat. POR 15 works great,but you'll likely want to paint over the POR 15. But it's kinda like the Ford vs Chevy debate. All about preference.

I've had the best results (and longer lasting, better looking results) with KBS Coatings - Paint Over Rust - Stop Rust Paint - Gas Tank Sealer - Gas Tank Liner

They also have a great line of rust inhibitors.

You can also look for Marine Grade Rust Inhibitors (I used that on my gennie '32 Ford Coupe and was impressed with the results, but it was EXPENSIVE, and I have to sand it all off again, because it went on slightly blotchy (not condusive to good paint job).

again, jsut my $0.02!

There's always Kersosene!

Undercoating is BAD. It traps moisture under the crap and trots the metal out without you even knowing it.

I have to say the BEST combination I have found is using POR15 as a primer(and do EXACTLY as they say for putting it down) then topcoat it with Tractor Supply Lo-Glare Black. I has LONG lasting results that taks just a lil bit longer than the half assed methods listed above

The results speak for themselves
