That was always the problem, they were focused only on the tanning salon products. Now they've diversified, and that makes the company viable now, IMO. The technology was always there, just not the buasiness plan.
I just mentioned 1 product line but ya your right they have 2 more product lines for Dental and Tanning industries. Personally I feel their strength is in the Industrial industry (metal coatins, paint, injection molding etc.) but I could be wrong since all 3 product lines have their own niche.
Even If they capitalise on 1 out of the 3 product lines then still this stock is VERY cheap.
