I used to use zaino z-pc, good stuff and liked the results but was pricy for a small bottle. Today i used the optimum polish the first time since i been reading that it had a good work time and many of you guys liked it, but i had a bit of a hard time, seemed it dry out too quick, i use a good amout each time and i did try to spray some water on it and last a bit longer. the weather was cool out today, used a rotary with megs. polishing pad, maybe im doing something wrong? any tips? and is this stuff suppose to be very thick? i can hardy shake it in the bottle, and take a little effort to squeze out.
