So I'm currently suffering a bad case of GAS (Gear Acquisition Syndrome), which is making me consider getting a new lid despite my current one being perfectly fine. Then it occurred to me. Why don't I get one with a solid colour and stick some decals / logos / stickers on it? Someone told me not to as the glue may damage the helmet. I've been reading around, found plenty of arguments for and against this theorem, but haven't had any luck in finding empirical evidence to support either side. So I'll just throw this one out here. What do you guys think?
