Hello Bob,
I assume you must have had a bad experience with mag particle testing results. Would you please elaborate on your reservations of the mag particle test. With fluorescent dye, a UV lamp, and a qualified tech its should be very effective.
Also inexpensive dye penetrant tests kits (cleaner, red dye, and, white powder developer) available from your local welding or industrial supply are much better than a unaided visually inspection. Dye penetrant testing is considered less effective than the mag particle testing by industry.
