If youve used it, which I assume you have, you wouldnt say that. Lets assume youre not winding me up here.
Months Protection on bare paintwork, easy to use and glossy. Beads and sheets well.
Ive never used C2 and probably wont, because If i ever use a spray sealant, it would be megs 135, and I wouldnt use that except in winter anyway.
Looking at the review of C2 on DW, im sure its a little better and much more durable but....
£120 just under for 1 Litre.
vs
4.5L for £30
Also, Megs 135 provides beading like, if not better than that, and after a wash provides the same sheeting and beading as that does. I use it because its ideal to spray down a company hack after a wash and if I used C2 it would cost me more money than I earn.
