Ha haaa ,
Haque Sir Just Greasing My Hands With that Black Filthy Plastic .I Have a Few Questions For You All .If You See This Picture You Will realize The Coating is Not Removed In Few Tighter Spots Like Between Main Card Reader Connection .How does One Target Focus On That Area .The 1000 Grit Paper Was Used Initially And Then the 2000 .Would Like To Take a suggestion When To Flip The Sandpaper From 1000/1200 To 2000 .The Fiber Pen Was Too Abrasive

you don't need to get it all off. on normal monoliths, you would solder to parts such as circled. NOTE- these are not the right points, I don't have this pinout available, this is only an example.

The only reason you would remove all coating, is for a catalog photo to ID like devices in the future. If you know the pinout, you only need remove coating to expose these solder points and that's all. we are not making beautiful art here, we are recovering DATA!!

these may lead you in the right direction:
