so far, other than spritzing the front end fasteners with ACF-50, I have done nothing but drive it.
I've gone around the M3W with a sister product (Corrosion-X). My new best friend. Found some threads that were rusting. Light wire brushing followed by corrosion treatment. Excellent strategy.
When I had the M3W up on a lift for the oil change, took the can around and spotted every fastener I could. I think it will have long term benefits--especially in a vehicle with mixed steel & aluminum. Only the owners of Amphicars might benefit more from it.
