Query: Extension does not fit into the spray head.

The extension tube is too fat to fit inside the spray head making the can unusable.Product may be OK, but what good is that if you cannot get the spray where you want it.I finally found a spray head from a "canned air" blaster and was able to put it on this can and apply the product.I will never buy this brand again.
