Shelf life for Klasse, PPCL, IHG?

[offcenter]

I was wondering what the shelf life is for various products are such as:



Klasse AIO, SG

3M IHG and SMR

PPCL



Would a good shaking of the bottles suffice after months of non use? The reason I am asking is that I was wondering whether to buy some PPLC and SMR now even if I won`t use much until the spring time when I will detail both cars. I also have some IHG that is over a year old, when if ever is it time to chuck the stuff and buy new? TIA:confused:

From what I`ve read, not many people have had shelf life problems with any of the synth stuff we use. Some have gotten fungus in their carnuba.



I know that SG is a waterless formula so it won`t rot on you. It might skin which would involve shaking. But the petrolium distialles and acrylic it contains doesn`t react to much (it`s why it performs so good out of the bottle), that and most things that have shelf life concerns are usually have expiration dates.



I know Klasse is `70`s technology, I figured they were all manufactured in th 70`s too ;)



As for the other stuff, it`s solvent based also, it`d last as long as, let`s say spray paint would, however that much is :)

1-2 years is certainly nothing to worry about. Laters.
