The bed of my Ram and the TJ tub were both done with Monstaliner.
I half assed the truck bed when I needed to remove the plastic drop in liner so I could bolt my rack on. I only used 1 gallon instead of the recommended 2 gallons for a long bed. Unsurprisingly it chips if you scratch it because it's thin, but it doesn't peel from there. I have a second gallon to recoat if I can find the time. Also, I rolled this job.
The TJ tub I did with an underbody coating gun and used a gallon as recommended. Much better results.
I'd recommend the stuff for an older truck or Jeep. I wouldn't put it on anything minty fresh.
