I sandblasted, and epoxy primed a rear axle back in August along with a car body. Blast material was "Black Beauty".
After sandblasting I cleaned the axle with waterborne grease and wax remover, then shot the epoxy after ~1hr, in total I did 3 coats to the axle, and car at the same time.
The axle has sat inside on my shop floor since August, I picked it up to start assembly and noticed what looks to be rust coming through parts of the epoxy on the cast center section.
The car body had also been sandblasted at the same time, with the same material and does not have any of this coming through.
Any idea where I failed?
How would you fix it?
