I hope this is useful to someone out there. I stored three blue EW pc bullets and three HF red bullets in enough titegroup to cover it all in a medicine bottle. The Eastwood has been exposed for 2 days longer than the HF red, though they have not changed and have the same tacky feel they had on day 2.
The total is 8 days for Eastwood, 6 days for HF red.
I have included the following pictures to compare appearance of the pc coat, and it’s durability as I drag the base across the paper rather firmly, but not enough to tear the paper.
Wish I had done this test before I powdercoated and loaded about 1500-2k rounds. Live and learn, I encourage others to do the same with your pistol powders.
I assume all powders will do this to some degree as igolfat8 mentioned, but if a powdercoat can withstand TG for a week, you most likely have weeks to months of trouble free blasting with powders that have considerably less “stank” on ‘em, as it were.
I will be keeping more HF red bullets in TG to document their long term performance, and integrity/durability of the PC coating.
