Happy holidays all. Recently found an older can of 3M Super Trim Spray that won't spray. I removed the spray nozzle and soaked in paint thinner for about a week. I took it out today and noticed a dried piece of adhesive blocking the spray nozzle air way so I took a small nail and managed to remove it. After re-installing the spray nozzle and shaking the spray can vigorously, it still will not spray. Any ideas on how to fix this problem?

all input and ideas are appreciated......

Lol no ideas, just respect and admiration for your thrift and tenacity.

You may still have adhesive in the spray channel. Try soaking in acetone.
You may also be able to use a substitute nozzle from brake/carb cleaner or undercoating spray cans should work.

Thank you, I have some acetone so I will try that first. If it doesn't work then as you say perhaps a substitute nozzle may work.....

Re pressurise the can with compressed air

Thanks for link. I was not aware you could recharge them. OK as long as you stay away from MAWP of the can. I can't imagin it being much hogher than about 150 psi.

Nails are far too big to clean the passage, use one wire from a hand steel bristle brush .

I don't even yank the bristle out ~ I use one of the edge ones that sticks out at a crazy angle .

I've been doing an engine overhaul and dug out some 40 + year old Foo-Foo cans of paint , I was well pleased when most were still perfectly good .

Don't forget to shake them very well for at least 60 seconds, time it with your watch else you'll stop too soon .

I agree, if rotating the spray head after you've cleaned it with a wire, typ depressing it and rotating in in the can as it's depressed .

Mind the nozzle's direction ! when it begins to spray you can ruin your working clothes .

DO NOT try heating the can ! if it's cold to the touch you can leave it in the sunlight but occasionally the cans will burst so tread lightly here .
