You actually say some really clever and insightful things when you feel like it I wish you spoke up more like this.Take some pipe cleaners and dip them in both a RTU and a full strength solution. Drape them over something and allow to dry. Then place them over a BLACK piece of construction paper. And then brush them onto the paper and SEE what if any polymer flakes onto the black paper. The film formers will coat and be reluctant to chip off. Up to you to decide if that is good or.......................BAD
Steer clear of white or yellow crystals. The CLEAR ones will reflect light on the carpet and make it sparkle!
You can buy direct from dsc now, if you don't have a local vender. Funny that the only place you could get dsc from is my local supplier.I started off using whittakers crystal dry . Then found out DCS's Spin Vac was the same and sold in gallons. Dried into a very nice "CLEAR" crystal that shattered very nicely. Could only order it thru barker hammer and shipping was expensive. Hence I now use BETCO's FIBERCAP MP.
