Gentlemen,
 
I am forwarding some pictures that David Hernandez took today.  These pictures are of areas that appear to contain micro bubbles in the finish of the clear coat.  These micro bubbles
could have been caused by humidity from the creek, irrigating the sod, or the clear coat drying before all the gases in the clear coat could escape.  
 
 
Thanks

Robert, 

These areas have what appears to be tiny bubbles entrapped within the clear coat.

 

It almost seems like moisture exposure.

 

I was thinking maybe humidity came off the river so I slung a sling here next to the river and got 98 dry & 81 wet which is 48% RH

Steel temp right now is about 110 @ 11:30AM

 

Both arches have the tiny bubbles
