Priming

Today the weather warmed to 27C; it only needed to be 17C in order to prime the boat.  I hauled it outside and mixed the primer. I used 5-Star Xtreme primer #5424.  It is a hybrid of epoxy and acrylic polymers, which provide excellent adhesion, good corrosion resistance, productive dry times, and ease of sanding.  It was mixed with an activator (#5426), and a reducer (UE60), at a ratio of 4:1:2.  I applied many light coats at intervals of 20 minutes.  The pot life of the mix is 1 – 2 hours at 77F.
