I know about the tool to analyze the paint. This is actually not my concern. Though there might be a slight visual problem. The analysis yields matching percentages of existing paint formulas. If the best match is below 90% than there is a visual difference. But what if there's currently laquer paint sprayed on the car. Laquer isn't available anymore only waterbased paints requiring clear coat. So if paint only parts what is with the area where old and new paint sytem come togther? At the moment I consider ising Owatrol Oil that creeps in the rust areas and reacts with rust resulting in a coat, which has to be renewed once a year.
