I was going to rhino line grill acidently bought undercoating would it be fine to just spray on some rhino line over the undercoat because the undercoat scratches I so messed up thats what i get for not thinking i guess

 

YOu really need to use some acetone and remove the undercoating. The rihno lining has to bond to the hard surface of the preped grill.

 

mineral spirits will probably work well too but you definatly need to remove the undercoating unless the can said (paintable) which is a little differant than regular undercoating

 

im confused

you were going to rhino line your grill but you bought and applied undercoating?
as far as im aware you have to go to a rhinoliner shop to get rhino lining done, its not sold in rattlecans. and i dont think rhinoliner does anything other than rhino lining so its not like you could have accidentally ordered the wrong service.

so were you actually looking for "Rhino liner"? or a spray can of truck bed liner?
truck bed liner has different requirements than rhino liner so you might not have to go through the whole removal stage

 

I Removed all the undercoat actually came of easy cleaned up nice with acetone and re sprayed with bed liner looks great. Thanks for all the help guys.
