Hi SPman,
You're right, it is a pain! I've had to apply the decals to my Rothmans Porsches; Silk Cut Jags; John Player & Gold Leaf Lotuses (or is it Loti); Team Gunston & L&M Lolas; Gitanes Matras & Ligiers; Lucky Strike Mazdas; and Marlboro Sigma & McLarens.

Unfortunately Steve is quite correct in his post. Tobacco advertising laws prevent all model manufactures from pre-applying the decals. At least Spark do supply them with the model - some model manufacturers don't.
