Personally - I would doubt it.
I have a few products now too - I have some clearkote, wolfgang, P21s, poorboys etc - and short of some minor differenced in looks, that (to be honest) only us autopians can actually see) this standard of product are all pretty good.
That said, I believe UPP is very good on light coloured cars and silver in particular - so I guess I should try it but I would probably still think "Hmm not bad, a bit like xxxx (insert product here)"
You coud try to organise a group buy if you want - share the shipping around?
