George, I used the Weapons Shield and I agree it is a great product. It loosened up my slide on my XD40, my autoloaders and even the gates on my revolvers. WOW.
I am glad that you are back in the pink and doing well, hope all the chemicals weren't the cause of your illness. Glad to see your back.
I just ordered a 16 oz. bottle, should last me a while cause in winter I don't shoot as much as in good weather. You should make a mill on this product.
