3. Even after performing 8-10 passes on an area, if the swirls remain can I assume I have not taken too much clearcoat and perform another 8-10 passes, if necessary? I obviously don't want to burn through the clearcoat but something tells me as long as the swirls remain, I must not be removing much, even if it means much more passes than the 6 that is generally recommended per section.
1. If your pad isn't turning the color of the paint then there is still clear coat to work with. It is impossible to tell how much is left without a paint thickness gauge.
2. That question is impossible to answer. As you correctly stated there are an immeasurable number of variables to take into account that would make an estimate like this not possible.
3. If you do not have a paint thickness gauge the next best tool you have is learning the history of the paint. Has it been in any accidents? Has it been repainted? How often has the vehicle been detailed or polished? Also, if you have done 8-10 passes and you are not getting the results that you want it is time to up the aggressiveness of your pad/products to expedite the process.
What machine/pads/products are you working with?
