PB Blaster Surface Shield Undercoating

For those that undercoat or live in the salt belt, a family friend had me spray his brand new 3/4 ton Ram in PB Blaster Surface Shield this fall to try it out. We used a 5 gallon bucket with an undercoat gun, used roughly 2.5 gallons for his Ram, about a gallon total to touch up my runner and my old man's Tacoma (Used FF last year), and another gallon for my Volvo.

Ram owner came to visit today, and so far I'm very impressed with the stuff. Even with this incredibly salty and wet winter we're having in northern VT, it's showing absolutely no signs of coming off. High spray areas just built up a nice layer of dirt as expected, and the rest is still glossy. Holds up way better than FF / NHOU in my opinion, and doesn't reek when you spray it on either. I've used the other 2 for years as well and both work just fine, but just seem to spray off much more easily.

The roads here have been soaking wet with salty brine almost every day since late November, and it's still just as thick as when it was sprayed on. My Volvos coating is holding up just as well, as is the 4Runner, though that doesn't see much winter use.

Regardless of what you use, anything is a hell of a lot better than nothing in the salt belt. But I'll definitely be using the PB from now on!

And just as another apparently controversial tip, you can use sections of toilet ring wax to plug up your factory frame holes in the high spray areas to keep the salt from your tires out of the boxed sections of your frame. Or really anywhere else you don't want it. I've been doing it since 2014 with great success. But take that with a grain of well, salt

(TL;DR, PB Blaster Surface Shield is pretty damn great and I highly recommend it over the other oily coatings. At least thus far)

This stuff looks like it's the ticket. Just watched a youtube vid on it and I'm impressed.

 

Good to know. Might look into it next year. Any sort of issues you saw applying over old FF? Ive got like 10 coats of FF on my truck haha

Also thats a pro tip on the wax ring. Will look into that this summer

 

I would recommend it to anyone! It's holding up well above and beyond my expectations. The only advantage you would get with woolwax or FF Black is being able to really see where you've covered. Beyond that this stuff is leaps and bounds better in my opinion

 

It seemed to stick fine and just cling to the FF, if anything it creeped through it down to the metal. This stuff seems to stay really wet even with a dirt coating, where FF kinda dries out and falls off after a while in my experience.

If you get it in a bucket it is very, very thin comparatively. But still does a great job holding on. And yeah! Highly recommend the wax rings. Insides of my frames have always been clean come time to spray them out in the spring.

Heard on the youtube that the black stuff just has this mixed in with it.

 

4 month update with daily winter driving, still holding up amazingly! Seemingly no loss or signs of washing off, and continuing to build up a layer of dirt.

It's a mess and not pretty, but it's way better than rust!

 

Does anybody know how long this stuff takes to dry? Or does it remain a wet film?

 

It never dries

 

This is interesting as Ziebart is my only option around here, and that's at $500. Thought about doing it myself, but I've never done it before so I don't know what to avoid/spray and what to get. If I do it, I'll look for the PB. Is there anything you want to avoid spraying or is it just a free-for-all undercoat type thing?

 

Anything rubberized or tar like is a hard no. Ziebart being one of the worst

Any of the oily types are just fine
