Abstract
A method for improving the paintability of a shaped object of which at least the outer portion is made of a polyamide/polyolefin alloy, wherein an electrical discharge is made to act on a gas in order to create a cold plasma type reactive gas stream, and the shaped object is brought into contact with the reactive gas stream thereby produced and with an oxygen source in order to oxidize the surface of the shaped object. The method is particularly useful for treating trim for motor vehicles as well as items of garden furniture prior to painting.
