System consists of three parts:
Alumni-Chek Cleaner - AC-1 is used to prepare the surface you're testing.
Alumni-Chek Penetrant - AC-2 is applied to the area
being tested. Allow the penetrant dye to stand for 1-5 minutes for
normal cracks and up to 20 minutes for extremely fine cracks. Wipe off
excess dye to prevent false readings. If the dye has hardened, spray
lightly with cleaner and then wipe off excess die.
Alumni-Chek Developer - AC-3 is used to develop the

heavy application. Allow the developer to dry for 30 to 60 seconds then
inspect the area for the cracks that will show bright red.
