Looks great, top job on the paint work. What are high tech decals? Not heard of them before. I'll have to do a search and see what those are.
Sanded tyres do look a lot better. I didn't sand my RA272 tyres, as they looked good already, but I'm currently (well trying to) buidling a C5-R and I will sand the tyres on this, no doubt about it..
Keep up the great work.
