I can't actually say for certain but I always ask the supplier to send me some samples along with my actual order so I can experiment first.....generally speaking I've found that both waterslide and vinyl are ok if they are first sealed with several very light coats of aerosol lacquer....allowing each coat to dry....the sort Halfords would sell. For instance, if on the tank, I've found that petrol proof lacquer will damage one but if you seal first and let it dry before using it then its ok....
