I apply to the whole vehicle then immediately start removing, starting with the area I applied first. That's always worked well for me.
this is pretty much it! ALTHOUGH, i actually let the 845 sit for a whole hour before i buffed it off. I guess i was thinking i'd let it saturate into the paint but that's just me. It buffed off so nice as if it sat on the paint for 1 minute. Such a great product. This may arguably be my go to LSP as far as waxes go. Im still trying to see what sealant i like....
