Which products can be used interchangeably with dry suit seals?

The correct answer highlights that talc and lubricant are both suitable for use on dry suit seals. Talc is often used as a powder to allow seals to slide on easily, reducing friction when donning the suit. This helps to maintain the integrity of the seals and enhance overall comfort while diving. Lubricant, when used appropriately, can also help preserve the flexibility of the seals and prevent them from drying out or cracking, ultimately extending their lifespan.

In contrast, the other choices do not serve the same purpose effectively. Water can cause seals to stick or lose their efficacy, while corn starch is not a commonly recommended or effective alternative for maintaining seals. Vaseline, though it might seem beneficial due to its greasy nature, can actually degrade rubber and silicone materials over time, leading to the deterioration of seals. Baby powder, while it can be useful in some contexts, is not specifically designed for this application and may not provide the desired benefits. Hence, the combination of talc and lubricant stands out as the most reliable option for maintaining dry suit seals.
