I only detail my own cars and those of a few friends. Since my current car was six years old when I bought it a year ago as the third owner, I have no idea how the paint was cared for or possibly corrected, I'm thinking that a pain thickness gauge would be a good tool to have for my own car and those of friends who don't know the history of how the paint was cared for, if it was ever polished, etc.

As a non-professional, I have a hard time justifying spending $250 or more for a gauge as seen on AG. But I have seen some online for under $100.

I'm interested in knowing if any forum members have invested in one of these budget gauges and if they do they job as unexpected.

Thanks!
