Nreakfree CLP: Not in Edmonton
Is it possible that the authorities up your way have done something sinister to Breakfree CLP in their continuing effort to implement "gun control"? They've no doubt added something to the mixture at the border to produce the gumming and sticky mess you encountered? It's probably formulated especially for semi-auto firearms, using some "smart" molecules that detect the type of action they're being used on. I have no doubt the RCMP is at the border watching for trucks carrying CLP north - and when they find one they add their magic goo to the product, while their evil snickering is heard all the way to Ottawa.
My advice is drive down and pick up your CLP south of the border. Transfer it to a shampoo bottle and you should be able to get back across the border with your contraband.
