Decided to give an original UFO Drip a chance.
After using current chain for 2 years with Squirt (XTR CN-M9100 initially degreased of course), cleaned it 3 times through chain cleaner filled with alcohol and wiped it with muc-off cloth. Thoroughly cleaned chainring, pullyes and cassette as well.
Application:
Indeed, at temperature above 25 degree celcius, original UFO Drip is very thin and transparent, almost like water. I coated chain for 2 full revolutions until it was dripping. I was surprised that some black gunk was flushed from inside of chain links to the outside, dispite chain looking perfectly clean before application.
I left it dry for 24h and it looked less dirty than just after application, but I wiped outside of chain and chaingring/pulleys anyway. Still chain looked a little bit more dirty than after similar application of Squirt.
Impression:
Rode 100km today in dry and quite dusty conditions, and surprisingly, chain became cleaner (shed flakes of wax containing dirt by itself?) and what's more important, chainring, pulleys and cassette looks MUCH more cleaner than with Squirt after riding the same route.
All in all, very happy with result and will continue to use this orininal formula UFO Drip until this bottle ends, and then will buy new formula one. People here say that it is even better and easier to apply.
