Pulling the trigger on Lining Tub

[UNO_RACING]

Well I'm getting ready to pull the trigger on lining my tub with a product that is similar to Line-x with exception that its slightly more rubbery. I'm doing the interior preping myslef and was curious as to how much sanding I should do. Should I do a scuffed surface or should I go all the way down to the bare metal?

Also, do you guys think I should fill the gas tank drain hole (I removed the interior tank) or should I leave it.

Comments appreciated.

I would think a good sanding would be better than bare metal.
I would not fill the drain hole, Its there for a reason
Good luck!


edit...
Removed the tank for good or just for the liner?

The tank is gone..I relocated it to the rear.

You don't need to go to bare metal. I'd be a little worried about rust starting on the bare metal between the time you sand it down and when they spray it. Here's picture from when I had my Tundra done. Their guys did all the work. It's just needs a rough surface to bond to. As you can see, they didn't go to bare metal:

Hope that helps you out.
