operation what went wrong

I have had the same results with the safety paint when I started trying fluorescent colors. The paint is powdery when dry and unstable under the devcon. Go with Createx Fluorescents or oil based. Never had success with the marking paints. Something in thier chemical makeup just doesn't click with the devcon.

I've had maple plugs finished in varnish crack in a simular manner, like Slip said, even sealed Maple can expand beyond the capability of the finish( in my case the varnish, your cse the Devcon) I've never had the provlem with E-tex, I think it doesnt set up as hard and tends to give a little more, I've got plugs finished in E-Tex that have been bounced off some serious rocks, the plug is dented, but the Epoxy adhered to the paint/primer/sealer well enough to dent and not spring back away from the plug, if that were Varnish, it would have chipped and cracked.

Looking at the second set of photos, it looks to me that the failure is occuring between the paint and the primer. Did you sand the primer to scuff it before painting? Flourescent paints can be real funny.
