Hi Tom
1) Yes, micro-blasting for small areas.  Large areas - panic and dispair are recommended.  
2) we touch up with urethane.

Good luck!

We are considering using Parylene conformal coating on some of our
electronic modules.  I was wondering if anyone can provide some input to the
following questions:



1.      What is the best technique for removal of the coating, locally and
for the whole board?  I have heard micro-blasting is a good possibility.



2.      For military electronics, can I locally touch up with acrylic
coating on a board with parylene?





Thanks
