I am looking for a Conformal Coating/Potting Compound that I can coat boards with to
protect them from moisture that can be removed (component-safe solvent?) to do
repairs.

The boards will have SMT, through-hole as well as DB-25, jumper pins, headers, etc.
Obviously I’d protect the DB-25, jumper pins, headers, etc. during the coating
process.

I have found "Techspray 2108-12S" $21 spray can at Mouser that says it can be easily
removed for rework.  Is this a cost effective approach?

Spray, brush, or dip would be fine with me.

BTW:  I am planning on coating the DB-25, headers, etc. (i.e.: connecting pins) with
a non-conducting grease, etc. to protect them from moisture in the field.
 
Cheers,
