Got my car back from area motorsport, from what i can see without getting the car up and a few pictures i looked at on their phone, looks like a great job! Had mine cavity waxed aswel, and sealed behind the rear bumper. First time they've done the cavity wax but Rob said all went well.. I took my own underseal, used a medium car kit from Dinitrol that includes epoxy primer rust killer, cavity wax and underbody wax, bungs and aplicator gun. But they supply their own otherwise.
When i get chance at the weekend i'm going to get the car up on axle stands and have a look, and Rob is sending some pictures over so i'll post them when i get them! Great customer care, gave you the time to ask and answer any questions you've got and heard the kind of things i wanted to hear when taking the teg somewhere new for work.
Peace of mind, the teg is all set to face its first British winter now!
