I started using Meguiars after reading these posts after having used armor all as well, i'd have to say a much better clean finish and not greasy like the armor all counterpart, thanks for all the help guys

 

Ok....I will not doubt that, but on my vehicles the dash & seat cracking occured in the mid/late 1970's and involved 1965 mustang, 1969 Ford truck, 1978 Honda and about 12 commercial fleet vehicle seats in trucks that were 1 to 3 years old.

 

I quite using armorall because it attracted dirt. Looks great at first application, but one ride with the windows down, my dash had attracted all the dust within a square mile. Ended up being more of a mess to clean-up that not using it at all.
