If you're going through the trouble of removing all the potting material you might as well solder all the joints too. I used black Plasti-Dip to reseal mine, you could use liquid electrical tape too.

that was one of my intentions when inspecting. i am guessing it will need some attention.

sorry, let me be more complete:

Hairdrier + putty knife....

then carb cleaner to get everything clean with a stiff toothbrush

I actually went another route. I did mine using dental picks, and
a thin blade screw driver. However, instead of heat, I did mine
while the board was cold and the backing easily flaked off.
There was no need for carb cleaner.
Discovered it by accident as I started working on it during
winter in a non heated garage.

i got a chance at work to strip mine. it flaked off fairly easily. i would use a little heat the using a pick,would pop pieces out.
next a thorough cleaning. i plan on using a bit of liquid flux the help the solder to flow.
once all continuity is double checked, i plan on clear silicon for a cover. will try and post a few progress pictures later.

I think a putty knife on the back of the relay board would tear up more stuff than you can fix!!!!!
