Resto Rick undercoating or U-Pol Raptor liner?

71Beeper · May 13, 2025

I used the tintable Raptor liner inside the wheel wells on my 71 Runner.
I did not use a gun, I used a small 3" foam roller as the shuts gun does not spray upside down very well.

It's hard to see the finish in these pics as its all white.

I ordered the Raptor kit and should be here Thursday. I might try a roller but I don`t think it would go on thick enough for what I want.

Make sure you cover EVERY surface you don't want that stuff on. Lots of Youtube videos also.

Neither does Raptor Liner !!!

FWIW 4 quarts will not do a complete b-body underside from firewall back. What you see below is 7 quarts - one coat. Also, it really needs to be applied in a short window otherwise it needs to be scuffed before another coat can be applied. Do all your gun adjustments then shoot it in one coat. This was the "tintable" Raptor Liner and is a perfect match to the body color. For reference, the black is rubberized undecoating and both have the same texture.

The OP should be fine with a 4-quart kit. Unopened extras can usually be sold.

Factory undercoating did NOT cover the entire underside of the vehicle.

The factory undercoating was applied by two floor techs, one on each side of the raised body as it moved down the conveyor system. Later automated sprayers did not move around, either. They stayed in one place and the body just floated above them on the overhead conveyor system. The undercoating missed a lot of places because the two sprayers didn't venture under the hanging body but, instead just sprayed at an an angle of roughly 45 degrees, depending on their height so anything inboard of the sub-frames got missed in the process.

Note the absence of undercoating on the inner side of the sub-frame and rocker panels on this original, un-restored '72 Dart. Even automated sprayers missed a lot of spots.

Why would you need massive amounts of undercoating covering the whole underside, anyway? Do you plan to drive it on salt-laden snowy or slushy roads?

If you're going to undercoat the thing, do it the way the factory did it not the way Mark Worman does it.

I think those that do undercoating or Raptor lining are doing it to duplicate the factory look and/or just want something more chip resistant than primer or paint. My road runner was not a factory undercoat car so I am only doing the wheel wells like the factory would have done because I want he factory primer/overspray/undercoat look. My Barracuda is fully painted underneath because it is far from stock but if orange tinted Raptor liner was available back when I did it I would have done it in that.

If you want to tint the Raptor liner you have to buy the "tintable" stuff. You can chose from colors they offer but you also have the option of tinting it yourself - that's what I did with the same color as the topside. You can tint it with any brand of paint BUT you must order it with NO BINDERS. Basically, just follow Raptor Liner's instructions !!!

I used the tintable on the bed of my Power Wagon. I was hooked on the product after.

Sprayed on or roll on and is it easy to keep clean, had a truck that had bedliner on it ,never haul anything in it that would damage it but it was hard to keep clean ,gravel dust and red clay dirt dust left a flat dull chalk look and wouldn't come clean , look like it was on there for years.

I would imaging it, like anything alse, needs to be well scrubbed. Its not porous so nothing should stick to it other than stuff that would stick to any other surface. Mine hasn't seen the road yet but I can tell you this, its more durable than a painted surface - I've hit it with wrenches and the odd hammer blow with nothing more than a slight scuff that is quickly hidden with a wipe with lacquer thinner.

I sprayed the rhino liner years ago in the inside floor pan and under the truck so you can see the pretty yellow pan. As for the fenders I masked the under side and is all yellow. I had a special gun that sprayed it out and was scuffed before hand see pics. Black on yellow the best!!

I think you need a front end alignment! And you have carried that "Big and Little" tire look a little too far
