Hi!

I need to coat a piezo element with epoxy in order to protect the soldered connections and the fragile sensor, as shown in picture 1. 

I would prefer a clear flexible rather than rigid resin. 

I was looking at :

> EPOXY COATING RESIN

> EF80 FLEXIBLE EPOXY RESIN

> CLEAR EPOXY GEL COAT

Which one do you recommend?
