I'll be replacing the floor pans in my truck next week. I know I need some seam sealer but when Im finished I'd like to paint the entire floor and perhaps the entire interior of the cab. What primers or paint should I use?
Should I use an undercoating on the underside of the truck? How about the inside?
I will likely be installing a new rubber mat over the floor when it's done.
Thank you.
Others will chime in with their recommendations as well, but IMHO, I would visit your local auto body paint supplier and seek their recommendations. This way you will have access to the brand/materials that are readily available in your area, work best for your use/environmental conditions and be obtainable at a later date if you need more for any reason.
I would paint the floor with a good epoxy primer and then your color. I don't like undercoatings since they can hide moisture. The bottom of my truck is cleaned and painted with a black satin epoxy.
Rubber mat ok if you are absolutely sure there are no water leaks when raining otherwise you'll need to lift it and dry. A rubber mat is like an incubator when combined with water.
Thanks for the advice guys. That was actually going to be another question. Normally, is the rubber mat held down with an adhesive or does it just sit on top of the insulation/pad?
Look into POR-15 products as well as a brand called Master Series. Both are great products, somewhat easy to use and very high quality.
I've used the POR-15 for floor pan issues in an '03 E250 caused by those infernal factory mats. They absorb and hold moisture---you'd be surprised how soaked they become over time.
If the rubber mats (entire floor) are such a problem than maybe I should reconsider a carpet kit. I can just put some good rubber mats over the top that can be removed and washed. Cause I like to get dirty from time to time.
Thanks for the product advise too. I've got the old pans cut out and should have the new ones welded in in the next couple days.
If you are putting new steel in then I don't think POR-15 is what you want to coat with. They say it needs to be placed on top of a solid rusty surface and that isn't new steel. If you want to use a barrier to protect against rust then I would look at Zero Rust instead.
POR-15 is intended to "paint over rust" however its pretty amazing when applied properly over any metal, such as the OP's.
Yes there are indeed a lot of great over coating products for new metal welded into an existing body so the field is wide open. Get the best, apply it according to directions and you should enjoy a rust free floor for a long, long time.
Ok so I sealed the floor in the cab and painted with epoxy paint. Came out great. Still gotta seal from below. I ordered carpet too. Decided against the rubber flooring.

My question on Rust Zero is how good is it for chassis frame and dirt roads/national park roads/out back/etc?? Thinking out best for rocks/etc.. I was going to use professional rustoleum or RB.. But may do Master series silver and top coat! My issue is I need to brush, cant spray.

Rust zero can be brushed or sprayed. I would think that it is a lot tougher than Professional Rustoleum and would hold up well on a chassis. I brushed it on my frame and cab bottom after cleaning it all up. Used a good brush to minimize visible strokes.
