crenwelge Good advice to RP14 have shade tree'd my whole life on this stuff,when I went to work in the aircraft magnaflux shop I found out what real magnaflux is ! Some guy with a magnet and some dust may find a crack that you can see across the shop but on aircraft you have to do better. Then you sign your life away !! Next thing is getting powerful magnetic field out of radial engine parts,so you learn, that was 52 years ago guess it worked never lost one. We could check those 6-banger heads caught several too !!
