+1 for do it. It's easily reversible. This is the beauty of plastidip. Just make sure you get enough coats on there. If it's too few coats, it will not bond to itself very well and it will be a real pain in the ass to get it off. It will still come off, but you'll have to rub at it for a while. 4-5 coats for good coverage and it will come off like a big piece of latex when you want it to. I know it seems a bit counter-intuitive that adding more will make it come off easier, but trust me, it's true.
