Thread: under floor paint

Tweet

I'm thinking of using a truck bed coating for the underside of the car. My father in law had his inner wheel wells done on his new GMC with Rhinoliner and it's looks really slick. Does anyone know if you have to prime or paint it first or can you put that type of product onto bare metal?

I've done it on a few pickups intended for street use, I've always used an epoxy primer first.....guess I don't know for sure if it's essential or not but I just don't like the idea of putting the final material onto bare metal.....?????

Makes good sense; thanks, Dave!

The hot rod shop I go to used it recently. It was sprayed on over primer. Looked fantastic.

My dad has it sprayed on his running boards, in place of those glue on rubber mats,it was tinted to match the car, looks awesome and durable.

When I did my truck I did it straight to bare metal. It's only been about 5 months and the truck only has 3 months of driving and 6500 miles so far so it's way to early to tell. I'll let you know in 5 years or so how I like it.

i primered my running boards on the 29'er, then used rhino guard overtop.
it has the pebbeled look that i wanted,it has been there three years and no blemishes yet..

Lots of good info, guys. I'm sold on doing it.

After media blasting my 39 body, I Epoxy primered it, lined the complete interior, under carriage and wheel wells. Now, in the back of my Toyota forunner beach cruiser, I did the floor, it went right over the paint and it gets abused. I've used it for quite a while, as long as you start with a clean surface, your good to go...

After we replaced the floor pans in Daddy's C-10, we shot them with some primer and used Herculiner on the underside. The truck ain't on the road yet, but I'm hoping it will last a long time.

I had a Rhino Lining shot in one of my trucks back in '89 when it was still a relatively new thing; they rough sanded the entire area, then shot some sort of primer, then the lining. So, I would think a primer would be a good idea.

Does anybody know if rhinoliner will hold paint?

don't know, but it can be color tinted before it's applied.

Check out e-bay #220287849943. It's a tintable bedliner kit

Not for sure, but my spray -on bed liner is about 10 yrs old, has paint spills on it that have been there for years also. Seems to be sticking purdy' good.
