Well you could just sand it, but it will be almost impossibly difficult to sand the chrome off and down to bare metal and i highly doubt it's going to stick very well. It will probably flake and chip off very easily.

 

So when i did sand it i would have to sand the chrome completely off. and not just rough it up?
Which makes sense.

But im actually thinking about going with the raptor liner now. I dont know yet. Im goin to just think about it awhile i guess. and see what else you guys say about ether one.

 

With 2 coats of hurculiner over the holes we tapped it with a hammer just to see how it was going to hold up seems to work great. I am also going to use it to redo my rockers once I get some thin sheet metal and bend it in the shape they used to be. Then sand it down and heculiner it and she should be good as new. Stuff works great!!
