Ive been happy user of Seal N Shine for a few years now and been very happy with its beading properties. A few months ago I bouight a new `24 Giuia Quadrifoglio which I had wrapped in Expel Ultimate PPF on the front clip. When I got it home I applied Seal N Shine on all surfaces.. What I`m finding is that, while beading is top notch on all the exposed painted surfaces, the beading on top of the PPF is significantly less prominent. Has anybody else experienced this, or have an idea why this should be?
