I used this lube on all the rubber seals on my 2012 Honda Fit. I recommend using disposable latex gloves. Apply this lubricant sparingly. This stuff goes a long, long way. Rub all doors, trunk, bonnet with grease. The seals look like new and should swell slightly overnight. You can actually tell it by the increased distance between the seal folds. Wind and road noise around the doors has been reduced and the doors close tightly like they were new. Incredible product and worth prolonging the life of your door seals.
