INTRODUCTION:  I had my tub professionally repaired and my jeep painted a year and a half ago.  Since then, rain and rust have done a number on it and major rust areas have surfaced.   Not only that, my jeep takes a beating with tool boxes sliding around as well as getting scratched from various other items I use while 4-wheeling.  I bought a Herculiner kit and sat on this project for months until it got to the point where I was going to lose my tub to the elements.

The very first step is to remove everything from the interior of the jeep.  This includes the seatbelts, seats, hi-beam switch (just tuck up under the dash), the main wiring harness going to the rear of the tub, rollbar padding... you get the point.

Next step was to attack the rust areas with a wire brush.  Remove the rust the best that you can.  If you have a hole in the tub from rust, this is the time to cut it out and weld new metal in.

I then treated every area that had rust with POR-15.  Do what you can to seal the tender areas of the tub.  Powerwash the tub really good with soap and water to remove all the dirt and let dry.   If you don't have a power washer, you can do what I did and bolt the driver's seat back in and drive to a local car wash.  Be careful, you don't have brake lights !!!  (remember, you removed the harness?)

After the tub dries, take the scotch bright pad they give you in the Herculiner kit and scratch up the entire inside of the jeep where you plan to apply the Herc.   You don't have to go to bare metal, just make sure the paint is not shiny anymore.   

Now blow out, sweep and or wipe the dust out with a damp rag.   When dry, take the Acetone or Xylene and wipe down the entire inside of the tub.   This stuff is nasty, so wear your respirator when you do it.  Make sure you're in a well ventilated area.

The real pain in the ass about doing a bedliner project is taping off the jeep.  This step more than anything will dictate the quality of the job when you're done.   Tape off everything you don't want to get Herculiner on.  For any threaded holes in your tub (like the ones that hold the seats in, seat belts, etc), use masking tape and screw some into the hole.  This will keep the Herc from gumming up the threads. 

NOTE: I didn't remove my roll bar because I have a full cage in my jeep, it's black, and I wanted to actually seal up the seam around the roll bar cleats to be absolutely watertight.

Notice in these couple of pics that you don't have to remove the tailgate as some would suggest.  Just tape it off really well.   Herculiner when sprayed on, doesn't really over spray much at all so using newspaper along the sides of the tub will suffice.   I found that I didn't even need to paper the windshield after all.
Ok, now you're ready to spray (preferable method) or paint and roll your Herculiner.   Spraying this stuff is THE best alternative and absolutely provides a much more professional quality in the result over rolling or brushing.

If you can, take the jeep outside in the sunlight.  Herculiner is super toxic to inhale so use your respirator!   The sun will speed up the curing time in between coats (you'll be doing 3 coats).   

Set your air compressor at 40psi and spray the Herculiner 10-12 inches from the tub.   Herc kinda splatters out of the undercoating gun, but that's what makes the rough texture.  It can quickly pool into small puddles, so keep the gun moving back and forth. 
Ok you may have noticed that I'm not wearing coveralls or even long pants.   Not the greatest idea, but I actually ended up only wearing a little Herc on my legs and clothes.  It's tough as hell to get off your skin.  Best thing is to use water and literally scrub and pick it off of yourself.
This is the result after only 1 coat.   What a huge difference!  Notice that there's hardly any over spray if you take your time and don't get crazy with this stuff.  Wait anywhere from 20 minutes to an hour before going on to the second and third coats.  You want the Herc to start setting up and only be "tacky" to the touch.
After 3 coats we're getting really happy with the outcome!    I pushed the jeep back in the garage and let it cure overnight.   The following morning I used a regular paint gun to spray the UV Protectant over the Herculiner.   I did this because Herculiner fades to gray from the Sun and this stuff is supposed to retain the glossy, black finish.   I'll let you all know after the Summer :-)
Here's the finished product!  The tub looks like new and now has a tough, durable lining to fend off the elements and my size 13 boots...
If this picture doesn't convince you to go get a kit of Herculiner tomorrow then I don't know what to tell you.  I was extremely happy with the outcome of this project.
Here's shot that shows how nicely the tailgate came out.  You can also see that I didn't go all the way up the firewall.

This was a terrific upgrade to my Jeep.  If you have any questions, feel free to email me at jimadams68@comcast.net
