Risky . . .
I wouldn't mess with it. I'm on my second set of Ram bars (the first were cracked in an accident). My first set had a pretty thick coat of lacquer over the stickers, but my current bars don't appear to have as thick of a top coat. The "i" on one side of the bars peeled off recently. For some reason it looks like the finish underneath the stickers isn't as glossy, and there is a small indentation where the "i" is missing. In theory I think the bars would look nice sans stickers, but I don't think it will be an easy process to do it right.
