Yeah they are not cheap i suppose. But Imo i would be very careful using rotary on first go. Amount i have seen about that people have used with no clue is amazing and just wreck the paint. Well they have to get someone who knows what they are doing to tidy it up. I dont profess to be an expert just advice really

Cally you right the German cars have mega hard paint, my Passat and BMW where nightmares getting swirls out. On the other hand my Type R had the softest paint ever!!!!
