So far I've managed to avoid Caig's "super straw" fiasco. Note that Parts Express has some old style cans of D5 they are flogging at a slightly inflated price, if I'm not mistook 17.95 $ a can. Just ordered 2, so I should be set for the next year.
If the future does not bring a return to the old type spray, or a better improvement, I'll be brewing my own D5 and dispensing it from a "glue bottle." Typically 1 oz or less flexy plastic bottle with a steel nozzle. We're back to the late 70's in applicator technology. Might as well call the stuff Cramolin again. Back to the future!
