problem with "any/all" chemical products like Armour All etc which promises you Purrfect Shine Forever etc is they ooze
gases for weeks after applied which in turn leaves a sticky,oily surface that collects grime worse than before on dash-
boards etc. -It even makes the windshield go cloudy and grimy.
My best SECRET TIP is to buy a bottle of Glycerol (glycerin)at the chemists.ALL natural stuff.Good spouses are known
to use it to avoid cracks in the marzipan-lid when they show their love and gratitude and bake you a sponge-cake All
of your own....
Do not apply directly onto surface but soak into rag ,then apply,but be prepard to wipe exess off after a day or so as
exess will turn up as "drops" but that only means you have sufficiently covered the part..
Also-If you have a Rock-hard and dried-out rubber-sealing ,say around window,rub the sealing a couple times,give it a
day or 2-wipe off exess -and you Will not believe your eyes!! -The rubber has magically got its suppleness back again!
(Of course it can't cure Cracks,but before you send the guys in white coats to take me to an nice place-just try it,ok?
That reched leak you have should also be fixed if you use a screwdriver between pane and seal to get some into there
as this stuff seems to "swell" the rubber just a tad..
It can safely be used on plastics,rubber,naugahide and marzipan sponge-cakes
