The US Roundel was introduced in 1917 and painted on US Military aircraft from 1919-1941. The design coordinated with the colour and style of roundels used by French and British allies. After the Japanese attacked Pearl Harbour in 1941, the red circle in the centre of the star was removed, to distance resemblance to the Japanese flag. This resulted in the US Stripes: a white star within a blue circle (stripes on either side) that is seen on all US military aircraft today.
The Frekote 770-NC synthetic mold release I ordered has a 6-month shelf life from the factory. The can I received on 8/25 was set to expire on 8/31 according to the date printed on the bottom of the can. I called and sent a photo of the can bottom and they said it should have been taken off the shelf a month earlier, so they will send me a good can when new stock arrives without sending the out of date can back.
I appreciate the fast delivery and them taking care of the issue, but it means you could be buying product that has only one month of shelf life remaining. Call before you buy and have them confirm the expiration date of their stock and if it is less than works for you, work out delivery from fresh stock or negotiate a discount.
