So today I ripped out all of my upholstery (stock carpet) and I bought a gallon of hurculiner ( Rhino liner bed liner stuff) I did this because I saw a bit of rust under my back seat. I found out that my passenger side was more rusted than the driver side, so much so that there were a few holes. the majority of the holes were dirrectly above the Cat converter! BEWARE! it was clearly visible from under the carpet and under the rig!!! I put extra herculiner there aswell as patching it with seet metal. it lks great too, having the whole inside of my rig super inpetrible. I recomend it. Another guy said he had drain plugs, I did not on my 92'. $53 for 1 gallon hrculiner and texture brush

 

POR-15 is pretty good stuff. It may not hurt to sand down th rust spots and put a coat of that on and then re-Herculiner it.

 

ya, already epoxyed the sheet metal on and super herculinered it until i can cut off the Cat converter and weld on a piece but Ill keep that in mind
