The Apollo Bioseal will degrade latex seals. It had a material impact on degrading my latex neck seal on my DUI drysuit over a period of a few months. I believe that the sensitivity of one's skin contributes to the irritation of the seal on the neck area. I've noticed that I typically get the marks more frequently when using the drysuit in salt water and when I am on a dive where I need to move my head around a lot (e.g. a working dive, or diving with a buddy swimming erratically that I have to constantly keep track of). I think that the salt must contribute to the irritation or abrasion of the latex seal on the skin of the neck. When I dive fresh water, I do not get the irritation on the neck at all. There's not much I've found effective for the irritation other than to just suck it up. Yes, it does suck.
