Does what it should but messy!
Used this to do an intensive undercoating on a 2014 Tahoe with 125k miles which were put on in the east coast rust belt. Shot with a pro gun, all went very smoothly with minimal amount of prep work needed, still holdin up well after 6 months. Down side? This product never dries which on one hand is a good thing for rust protection but anytime I’m working in areas treated I’m always getting the product on me and being in black its a mess! The stuff is like a creeping fungus, it will show up on my clothing sometimes even when I not doing mechanical work??? I will also see it sreeping out of places like the wheel wells and sometimes drip onto the ground in hot weather. I believe it is doing a good job on embedded rust to halt its spread and flowed easily to get into those deep areas but just be aware of the after mess for many months to come, your mechanic will hate this I’m sure.
