I did a video on it once. I had one coat each of base, colour and top coat and then went 'on the tools' and polished the hull of a 30 ft yacht. No chipping, still shiny at the end of the job even though my hands were wrecked!
Interestingly I'm now wearing Ikon.iQ Nails hypoallergenic gels and bashing away polishing up several vintage brass portholes with lots of nooks and crannies and fiddly bits. The performance is equally impressive.
Having just looked at my costs per service for all my product range I have to say that Bio Sculpture products are the hardest to achieve my margin. Out of the two I will concentrate on Ikon.iQ. Some Evo colours are one coat but most colours need two. All Ikon..iQ colours are one coat so I can get more sets per ml and it costs less than Evo.
