Rally decals

[Flatfour]

Ok, I`m contacted by a guy with a Lancia Integrale, full of rally decals...

How can I use my rotary on that paintwork without ruin the decals...

Some sort like on the pic, except that his car is bleu mettalic with orange/green vynil decals...

Can you safely use SRR or so on those vinyl decals ?

Nobody that ever has done such a car ?

I really need to know if those vynil stickers are "polish-proof"...
