Hi Guys.
   Is there anything like a consensus on the best brush-on/roll-on/spray-on bedliner? My old Sami died of cancer (I was afraid to slam the doors for fear the fenders would fall off), so I intend for this one to stay as close to rust free as possible. It was an Arizona/Colorado Sami, so rust is not an issue now. I'm thinking of bedliner for the entire interior, wheel wells, etc. Is there anything "better" than bedliner for wheel wells and underneath?
    Secondly, I know Rocky Road has them, but shipping is a bitch. Do any of the national retailers have 16" wheels with lots of backspace? I want to run 7.50 or 8.00X16's--tall and skinny. I want as much backspace as possible on a 7 or 8" wide wheel. Plain black, please.
    As usual, thanks in advance.

IMO it's hard t beat herculiner for a DIY bedliner ...

The prep work is the big thing tho. If you don't prep properly, they all will fail.

I like herc just cuz the feel isn't slippery. Some like duraliner for interiors cuz it is "slippery" so easier to clean. I just sweep the herc in my rig and never worry about it being "clean" 

  I have had good luck with gravitex rubberized undercoating

Speaking of prep work, I discovered this hand-held sandblaster gun at Harbor Freight that works great if you don't have a big job or a big compressor!

It has an 18 oz hopper that needs refilling more than occasionally if your job is moderate-sized so you don't want to use it to strip the paint off an entire body.   But for rust patches or cleaning up wheels, it works great!  It uses fine sand (NOT playsand!) that you can buy at  most lumberyards/Lowes/etc. or - even better - silica bead available at most auto parts stores.

The really nice part is the price:  Under 20 bucks.



Five wheels cleaned by the above sandblasting gun and painted.

A really good DYI value!

Just have it oil bathed on the bottom.  All the cars I've seen that lasted against the elements up here in the NE, Buffalo especially, were shot with oil at least once a year.  Bedliners and undercoatings do not flex with the body or frame when you're in motion so they crack.  This traps water and they still rot.  Bedliner would be great for wheel wells and the insides of fenders and the bottom of rockers, but oil is best for underneath on the floors and frame...in my opinion.

My herculiner doesn't crack ... I'll have to snap pictures of my rockers that were straight when covered and are now bashed in in many places and multiple times ... not one crack or flake (hardly even scratched).

If the surface isn't preped right, it will fall off, but done properly it will stretch quite a bit with the metal.
