i know there has been threads on this before, but the search funstion is not liking my requests. i have never had a problem with 105 "gumming up" before today. i shook the bottle harder than a paint shaker at home depot, sprayed my pad, sprayed my panel, and it is still gumming up like crazy. any ideas? i think i remember someone saying to mix some optimum polish with it. i have 105, the next hardest stuff i have is old ssr 2.5, and power finish, and optimum polish II. none of those can do what 105 can, but the gumming up is preventing me from doing any quick work.
