[madeinfrance]

Anyone bought these front, rear and side stickers? http://matramagic.co.uk/page15/page15.html#ecwid:category=165168&mode=product&product=370811
I just did and received them (quick delivery!) , but cant figure out how to apply them. Heatgun / hairblower?

Asked Matramagic and got the answer. No heat needed, only some water and a sponge.
