UPP has always been one of my favorite LSPs but the durability is lacking. Normally I wouldnt care as I LSP weekly but even after a few days it drops off. I been reading around Autopia and talked to some folks who say if you polly charge UPP that it keeps its initial look and feel for at least 6 - 8 weeks. So what are your thoughts on it if you have tried it and anyone wanting to sell a sample? BTW its -12 here right now with a -40 wind chill.
