unfortunately we still dont know what they do (publicly):
Business Description Stead-Fast Holdings Group, Inc., distributes products to the light truck aftermarket, including its own proprietary spray-on bed protection product which offers specially formulated polymers that permanently bond to the truck bed.
So this is current? (I actually investedin STDH a year or so ago and only noticed when it got back to my purchase price at end April.)
GO SRPX but please tell the world your business plan.
