I thought it would be useful to have a thread discussing what causes premature deterioration of each of the three main drysuit seal types. I have recently switched from latex to neo and during a call to John at Otter he told me that Sudocrem (which I have started using to protect my skin from getting the hangman effect) would not be good to neo.
Please help me fill out the following, explaining where possible what the key substances are and how they cause the respective seal types to deteriorate:
Engine fumes / fuel in general
Oil based products
Apollo bio seals
