Their products seem to be very good, if pricey. Gore seems to lack a functioning domestic system of customer support. It took me five+ weeks to get an issue straightened out with Gore. Once I got to someone with authority and inclination to help they were very fair and helpful.
Anybody want to buy some Dumonde Tech Lite chain Lube?
Dumonde says to judge the right time for reapplication by the chain noise. I don't know how the chain noise could get much worse than right after application. I reapplied Dumonde Tech three times hoping the noise would go away. It didn't. I had started with a new, cleaned chain. I finally gave up and went to Squirt wax emulsion. I had been OK with wax solvent lubes in the past except for their staying power. I'm hoping the Squirt will solve that shortcoming.
