I want to put that on my inner fenders front and back, on the under side of my truck and inside the floor pan. is there anything I should be made aware of. good brands to buy.

I used Herculiner from Auto Zone, easy to work with and does a good job

For the price, I think the kit i got off ebay is great. It's a 2 part epoxy, unlike the brush on ones. Comes with about 3 gallons of material for $180 shipped to your door. Check my sig for pics, it's called Extreeme Liner. I used it on the entire bottom of the body. It's super tough and sprays pretty easy. Comes with the gun, you just need a compressor.

Curious why you want a brush on one? They don't last at all.

why dont u just go to an undercoating place? be a lot cheapier then 180 . here they charge 110 for a full spray. call around first saves u on the the time and mess, it goes get messy! when a drop gets in your hair, have fuN! lol

I've had good results with Herculiner too. You don't even have to buy a whole kit if you already have brushes and rollers. I got a single quart can of it from walmart for like 20 bucks.

I wanna try and stay away with spraying it. I will be getting my car back from having it painted.

I used both and the roll on kind works fine for me.
