I say on.

 

I say leave it on, but the dealer splash does stink. On my original black tire cover with the dealer logo, I just used acetone to remove the dealer name. Came off easy. I ended up getting a sweet deal on a white cover, so I now have an extra black one with the word Hummer on it.

 

littlehummerboy...did the acetone do any damage or discoloration of the hard plastic cover? I guess I'll have to give it a try. What's the worse that can happen...I'll have a good reason to get a new one

 

Nope, didn't hurt the plastic. Make sure you are in well ventilated area, wear rubber gloves, and use a good cloth, microfibre preferred. I used a toothbrush to get little some little flakes off. After done, wash with soap and water several times, then wax entire thing. Took me about 1/2 hour to remove "DUECK GM, VANCOUVER, BC". Do not "scrub"hard, let the acetone do it's work and wipe off. Do not let the acetone touch letters you wish to keep.

 

If the acetone doesn't work try Krylon

 

On!!
