New A3 ordered in brilliant red & the salesman has thrown in ' free ' Supagard, now I've read lots about this being a waste of time & money etc :no:
As I'm not paying for it do I let them apply it anyway ?
Is it any good for say the first 6 months ?
Can I add a wax on top of it to keep the paint beading ?
If I use a good polish will that remove the Supagard over time ?
Sorry for all the questions but I've never had a car with it before :racer:
