Whats the hard and fast rule about a respray for your lid. I have a Schuberth C3 which I would like to have custom resprayed, can you do this without affecting the integrity of the shell or is it a case of you are stuck with what you have?

Q: What paints should I use when I want to paint and repair my helmet myself?
A: You can use car paints to paint and repair your helmet (available on the market). These may not be nitrocellulose-based, otherwise the helmet shell might be softened. We would like to point out that the ECE approval is invalidated if other caustic paints are used. In such cases Schuberth accepts no liability.
Water-based paints are recommended. We urgently advise you not to used solvent-based paints (which contain caustic substances)!
Q: What features should the helmet which I want to repaint have?
A: When you want to repaint a helmet, you should select a glossy helmet, then you will be confronted with fewer problems when sanding it down and you will find it easier to apply the paint evenly.

I suggest you take it to an approved/specialist auto painter.
I had one done at Rapier in Hull. Excellent job, but not cheap.
Mine cost £200 10 years ago for a simple 4 colour design (Ayrton Senna replica)
Alternatively, give it my kids. I can't promise on the condition when you get it back. I can promise that it will be very colourful
