After 62 days the outdoor evaluation has concluded. This past June was one of the rainiest on record. I did not post the failure date of the last three products on the date of the failure so I could lump them together. Here are the final products to show corrosion.
Frog Lube after 54 days
Hornady One Shot after 58 days and
WD 40 Specialist at 62 days.
The indoor evaluation is still on-going.
