What materials can be used for lubricating dry suit seals?

Using talc or water-based lubricant for dry suit seals is a recommended practice because these materials can effectively enhance the sealing capabilities while ensuring compatibility with the suit's material. Talc helps to reduce friction when putting on the dry suit, making the process smoother and preventing potential damage to the seals. Water-based lubricants are also safe for use as they do not degrade the rubber or silicone commonly used in dry suit seals, making them a suitable choice for maintaining the integrity of the suit.

In contrast, oil or animal fat can break down the materials in the seals and create a sticky residue, which is not ideal for maintaining proper sealing performance. Petroleum jelly or soap, while they may seem like practical alternatives, can also compromise the integrity if they are not compatible with the materials used in the seals, potentially leading to deterioration over time. The option suggesting that only water is needed overlooks the additional benefits that lubricants provide in terms of ease of donning the suit and maintaining a proper seal.
