206,
I use the original Rapid Tac or Rapid Prep to clean a surface before installing. But, just about any cleaner that doesn't contain amonia or parafins will be ok too. Call or email Roger or Jeff at Rapid Tac for some free samples and a distributor near you.
Grass,
If you'r egood at dry, don't change a thing. However, if you do a wet application, the setting time will depend on the liquid us use. From my experiece, home brews take too long to set. Rapid Tac will set in several minutes, depending on your technique and the media. And with Rapid Tac II, you may have a 1-2 minute window of opportunity to get it positioned before it starts setting.
Heat can speed up the process with some fluids, but it probably cause more headaches than it's worth.
