Here is a tech tip:
When exposed to subfreezing temps, the repo duckbills from Dan turn hard as a cigar tube. No way they could work properly. I brushed them with Dow Corning 200 fluid (dimethylpolysiloxane) inside and out and they turned soft as velvet. Examined them this morning with air temps around 15F and no change. The transformation takes only seconds and is quite amazing to see. The fluid which I used has a viscosity of 20cs, like a thin oil.
