GaryR Posted June 9, 2022 Share Posted June 9, 2022 I do enjoy trying out different wavelengths and filters at local car displays. These are visible and IR (likely 720nm) shots of a '52 Pontiac Chieftain taken way back in 2014, clearly showing body filler under the paint. Taken with a FS-Olympus E-P2. Link to comment
Doppler9000 Posted June 9, 2022 Share Posted June 9, 2022 What’s interesting is that the flaws revealed in the IR shot lead you to the same, less obvious, but still visible flaws in the vis shot. Link to comment
Doug A Posted June 9, 2022 Share Posted June 9, 2022 Interesting the way IR pinpoints the repaired areas. Quite unexpected to me. Wonder if it is possible to repair a car and hide it from IR? Thanks, Doug A Link to comment
Nate Posted June 9, 2022 Share Posted June 9, 2022 That is interesting and very cool. Wonder what UV would have shown. Did you ever show the owners any of the non vis shots? Link to comment
GaryR Posted June 9, 2022 Author Share Posted June 9, 2022 Poor paint jobs are easy to spot. IR just makes it more evident. I expect that a better finish and more primer coats, before the paint would hide those blotches. UV is limited to surface defects, whereas IR can penetrate the paint layers. Nope, I've never shown these to the car owners, but they may have noticed them in my online galleries. Link to comment
colinbm Posted June 10, 2022 Share Posted June 10, 2022 UV would show some batch differences in the paint, especially white. Link to comment

Wonder if it is possible to repair a car and hide it from IR? Thanks, Doug A As I see it here, the paint job is poorly done. Different paints or same paint that has been worn out by time will reflect IR light differently. Hence, the patches of new paint are evident. It would be possible to hide it from IR if the car was fully painted. Link to comment
Doug A Posted June 12, 2022 Share Posted June 12, 2022 @Marc del Piroexcellent point about repainting whole car. Wonder if that would hide areas with Bondo underneath? @colinbmbet you are correct. @GaryRthanks for the informative images and comments. Thanks for sharing, Doug A Link to comment
