One Year Later
It been about a year since I Herculined the tub of my CJ and I still think it was a great investment. Below are pics of what it looks like now.
This is what my Herculiner looks like after a year of sitting outside in the hot California sun. 
As you can see, the Herc has faded to a dull gray but in my humble opinion, it still looks good. 
Here is a close up shot. 
Herculining The Tub of Your Jeep

Well this has got to be one of the best mods I've done to my CJ. Unlike installing something useful like a new transmission mount or something like that, Herculining your tub will make your Jeep look like new (at least on the inside anyway) which is always a good thing especially when you're trying to show off :) In truth, there are a lot of beneficial reasons to do this to your Jeep. First and foremost, it will give you a reason to fix all the rust on your floor boards and provide it with a tough grippy finish. It will also help dampen road noise, absorb heat from underneath the tub, can be hosed off and is a great (make that better) alternative to carpeting.

What You Will Need
• 1 gallon Herculiner Kit
• Xylene
• Scotch Brite Pads
• 2" Blue Masking Tape
• Roll of Plastic Tarp
• Drill Paint Mixer
• Disposable Painters Coveralls
• Chemical Resistant Gloves
• Respirator with Chemical Inhibitors
• Undercoating Gun
• Standard Tools & Torx Bits

1. Remove everything in your tub that you don't want permanently covered in Herculiner. This should include your seats, seat belts and roll bar. At least that's what I did.

2. Vacuume and wash the inside of your tub using soap and water. Be sure to dry all surfaces before continuing. I also took this time to fix some rust that I found underneath the rollbar plates buy grinding it out and then treating the infected area with some POR15.

3. Using Scotch Brite pads, thoroughly scourer all painted surfaces that you intended to Herculine. You don't need to scourer until you see metal but just make sure the paint is no longer shiney. Wipe off all the dust with a tack cloth.

4. Wearing your gloves and respirator, rub Xylene on all the surfaces to be Herculined (Xylene is some serious toxic stuff so be sure to do this in a well ventilated area). Let dry and then with a clean dry cloth, wipe off any residue left behind. Your painted surfaces should now look pretty dull.

5. Now for the fun and longest part of the job. Mask everything off and plug all hole that will need bolts going through them again. For this, I just took small wads of masking tape and screwed them in by hand. Be sure to also wrap your shifters, brake, clutch and gas pedals.

6. To prevent overspray getting all over your Jeep, be sure to wrap all surfaces not to be Herculined from bumper to bumper. I also removed my tailgate and tranny cover at this time.

8. With everything masked off, covered and ready to go, put on your coveralls and open the can of Herculiner. Now this kit will come with a paint can opener but as you will soon find out, the thing is completely uselsess. This thing is a real PITA to open and I wound up using a flat head screwdriver and a heck of a lot of effort.

9. Once open, mix the Herculiner using a drill mixer until all the particles are free from the bottom and dispersed throughout the can.

10. I decided to spray my tub as opposed to rolling it and would highly recommend it to anyone thinking about doing this job. The finish will be consistent, level and look professional. Having said that, without thinning the Herculiner, I poured some into a sports bottle (my undercoating gun did not come with a bottle), set the compressor to 40psi and proceeded to spray my tub. Lay down a light even coat about 10-12 inches from the surface being sprayed. Be sure not to go too heavy as the Herculiner will just puddle up, take forever to dry and ultimately give you a smooth texture as opposed to a grippy surface.

11. Depending on temperature and humidity, wait about 20min-1 hour or until the Herculiner is tacky (more dry than wet) before laying down a second coat. Repeat this process and lay down a third coat. When all is said and done, I still had about a quart left in the can.

12. Wait a minimum of 12 hours before you take apart all the masking and re-assemble your Jeep. That's it!

Herculiner Revisited - 1 Year Later
I have had a lot of people ask me how my Herculiner has held up over time and whether or not I would still recommend it. Well, it has been just about a year since I applied it to the tub of my CJ and here is what I can tell you.

Unless you spray on some kind of UV protectant, the shinny black color of your Herculiner will fade to a dull gray especially if you ride topless as much as I do. This dulling and gray color does not bother me as it is at least uniform and has not effected the durability of the surface.

Another question I have been asked a lot is how difficult is it to clean Herculiner? Well, considering that all you need to do is pull the drain plugs in your tub and hose it out, I don't think it's too hard at all. Using a spray nozzle with a force full stream, you can really do a good job getting the crap out.

So, would I still recommend this mod? Of course! Click on the pics to the left to see what my tub looks like after a year of use and being in the sun.
