Ok well I am an idiot and posted this first in the apperance products page (DUH) then I looked a bit harder and my pea brain found the bedliners page. I currently have a drop in bed-liner (Ford Factory) and was looking at my friends Wrangler which has Herculiner throughout the tub. How hard is it to do in a truck? Will it even work well? The only reason I am asking is because the lip of my tailgate (bottom lip) is starting to rust a bit...I wanted to sand it down and get this normally not sprayed part w/ herculiner and then do the rest of the bed. I load my truck a lot w/ hay...bikes...concrete...you name it. I love the drop in but I hear horror stories. Then again my TAC said that as long as there is air flow (not super air flow but a bit) under the drop in it will never rust. His truck's have never rusted but he has a cap on both trucks. I am rambling sorry...

Concrete will definitely kill a Herculiner. Think about the wear in a Wrangler (feet and sleeping bags) vs throwing concrete into a truck. Read some of the bedliner threads (there's a bunch that include Herculiner). You'll find in spray ins Line-X gets top billing here. As I mentioned in the other thread, look at DualLiner and our old name DualComp - it gives you the dent protection of the drop in (good thing!) and better skid protection than any other bedliner.

I've explained in other threads my story and how I ended up working at DualLiner - in 30 years I never found a liner I liked, until I stumbled across this one.

 

So would Duraliner hold up to the concrete and stuff? Is there any way to specify for whoever is installing it to put it on the bottom lip of my tailgate.

 

Duraliner is a plastic drop in liner. The one in your truck may well be a DuraLiner.

DualLiner is the installable I mention. A DualLiner will definitely stand up to concrete - 2 weeks before SEMA 2005 I used a front end loader to dump 24 - 20# landscaping blocks into my show truck... had to drop them 20 times to get a couple marketing pictures. This is something you would never do with any spray in, unless you like dents.

Both of these are machined parts, so no, there is no way to do anything except what they are designed to do.

No matter what, you will have to fix the paint issues before you do anything - Herculiner and I believe all spray in liners do not recommend direct to metal installation.
