How do I protect my boat from getting blisters?

You should protect your boat with Interprotect before it ever goes in the water. Protection is always better than cure and it really does make sense to protect a new boat as well as an older craft. To achieve this protection it is necessary to sheath the hull with a water barrier to seal the surface. This is done over the existing gelcoat. There is no better time to apply an anti-osmosis system than when the boat has not yet been launched. However, it must be stressed that protective systems cannot stop osmosis once it has started, or prevent it from occurring in poorly constructed hulls. It is important that a full check is undertaken before starting. Remember as well that moisture may get into your hull from the bilges so always ensure good ventilation inside the boat and either keep the bilges dry or paint them well to seal the surface from moisture permeation.
