Faraway Posted June 14, 2014 Share Posted June 14, 2014 Hi all, So I've finally taken the plunge and applied OptiCoat on the car. Used roughly about 12ml including double layering the bonnet and top of the boot. This morning when I woke up I was wondering if I should add a second layer on the roof of the car. Wondering what is the effect of double layering? Does it add a thicker layer of protection? Some forums seem to suggest that there's no point adding a second layer. So should I add a second layer or keep the remainder for after the first wash to see if I have missed any spots? Link to comment Share on other sites More sharing options...
