In the vein of "not like the old days", I have a beef with duct tape. Todays product just doesn't seem to stick.
When I got my Puck, I decided to reupholster the cushions. On the underside was 30 year old duct tape covering the staples. I had to yank hard to remove it. Covered the new staples with new tape. It stayed on less than 2 weeks.
The front vents on my VW leak so I cover them with duct tape. Use to stay on for several years. Now? Couple days.
Don't tell me to buy a better tape unless you can tell me WHICH tape to buy.
