Herculiner How-To
I have been pretty busy working on my YJ lately (which means a lot of research on JeepForum). I have found a lot of great write-ups and figure I would attempt to give back by developing another write-up on using Herculiner inside a Jeep tub. :thumbsup:

(If anyone is interested, here is a link to a write-up that I recently created this month on Krylon Fusion Paint on YJ Fenders:

First I should say that I only Herculined from just behind the front seats forward, stopping where the floor raises up to the bed of the Jeep. I used a whole quart of Herculiner and I'm pretty content with the outcome. The following is a list of items that I used to complete this job:
  • 1 Qt of Herculiner ($25-$30; Menards is cheapest; 2 Qts if you plan on doing the whole inside of your tub)
  • Wire Brush
  • Essential Tools (9/16 socket, philips screw driver, etc)
  • Angle Grinder (Not required but helps with sanding, especially if you have surface rust like I did)
  • Sandpaper (80 Grit for surface rust, 120 Grit to finish final rough up)
  • Mask (To cover face)
  • Safety Glasses (Recommend if using Angle Grinder)
  • Masking Tape (The Blue 3M painting tape or the green stuff; think it's called Green Frog)
  • Clean rags (old t-shirts, etc)
  • Some cleaning agent (I used paint thinner)
  • Latex/Rubber gloves
  • Paint brushes (I used a 3" brush for the open areas, a 1 1/2" brush for the hard to reach places; I think the brushes work better than the rollers due to the floor having so many edges)
  • Shop Vacuum (Something to clean up dust, paint, rust, etc)
  • Soap and Water

I will add steps and pics tomorrow. Getting late, and gotta get ready for work and birthday. :cheers2: haha, damn, getting old.

I apologize in advance for how I am going to be posting this write-up with pictures. For some reason, If I use my Mac have not figured out how to add pics,but if I use my JeepForum Application on my phone I can add pictures. So I will be adding text with my computer followed by replies with pictures from my iPhone. If anybody can assist me improve this unconventional method, then please let me know. :)
  1. Remove seats, center console, shifter boot.
  2. Remove carpet, vinyl mat, floor cover.
  3. Disconnect wire going to driver seatbelt.
  4. Remove drain plugs from floor pan.
  5. Inspect the rust, oh wait that's me! :hahaha:

I wasn't able to remove the transmission plate that screws into the tub because I siliconed it last fall. It still looks nice if you're in the same boat.

I painted the whole tub last fall with hammered finish, but virtually every weather strip is bad in the jeep, so water got under the floor mats and caused havoc. That is the reason I decided not to paint the back because it still looks pretty good. I'm posting pics of the back for reference for anyone who's interested in rustoleum hammered finish.

As you can see from the pictures, the driver's side floor pan got hit hard. The rest of the floor looked pretty good, but I know that the more prep you do, the better the outcome is.

  1. Get out the angle grinder and go to work using a corse brush.
  2. Wear Mask and Googles.
  3. Use wire brush to remove loose paint, rust, and getting in corners, difficult areas.
  4. Use sandpaper (with sander block) and focus on any rust areas.
  5. Periodically sweep/vacuum debris up.
  6. Anything that you are painting needs to be sanded.

  1. Finish sanding.
  2. Final vacuum/sweep.
  3. Wash floor with hot soapy water.
  4. Dry throughly.
  5. Use paint thinner on rags and wipe entire floor.
  6. Do this very well to ensure that floor is very clean.
  7. (Side Note: I forgot that I put POR-15 on the floor pans to help reduce rust. The Herculiner did stick to it well. I just roughed up the POR-15 after it dried with a scotch brite pad and repeated steps 2-5.) :confused:
  8. Tape off any areas that you don't want to paint to give you a nice clean edge.

I forgot to add that all bolt holes need to be covered with tape before painting. For the seat bolt holes and drain plugs, I covered them up with tape and used a razor to cut the excess away so the tape just covered the holes. For all other small holes, I bunched up some tape and stuff them down in the holes.
  1. Open Herculiner.
  2. Stir for ever.:laugh:
  3. At least five minutes.
  4. Apply liberally, using small brush stokes and "pats."
  5. Remove all tape before Herculiner dries. It's a big pain if you wait to long.
  6. Let dry for the night.
  7. Take some pictures.

  1. Let the Herculiner dry before putting seats back in.
  2. Bolt down your stuff. (It helps to place nuts and bolts in separate sandwich baggies and label them so you know exactly what goes where.)

Well, Here it is. Thanks for checking out this thread. I will be posting more pseudo write-ups on other modifications. I am hoping to get a membership soon with JeepForum so that I can be more active. :shhh: If anyone would like to help me out with the membership cost, I would be extremely grateful. Just think of it as a birthday gift! :laugh:

Take care.

Did you only apply one layer or did you keep putting it on after I dryed a couple times?

Nice thread now I need to go and do this

Nice write up and good pics. It looks nice.

I have done this also to an old Land Cruiser and would not do it again. The Herculiner did not stand up to wear and tear at all. It would just crumble and chip if I put anything in the back that wasnít soft. I was surprised at how fragile the "bed liner" was.

It also does nothing for noise and heat dissipation if that matters to anyone. The floor in the Cruiser would get so hot (even though a heavy rubber mat) that my feet were constantly sweating after about 30 minutes into a drive. My wife would sit Indian style because of it and wasnít too happy about taking any trips in the rig.

There are better products out there but maybe none cheaper and easier to do. Next time I do it, I will probably use a good, textured paint or spray on version that isnít so rough on the skin or use something that is designed for heat insulation. You lose skin with the Herculiner if you arn't careful so not all that kid friendly.

It looked great though :D

The time now is 01:57 PM.
