My new clarinets just came in from a mechanical overhaul. I noticed that a clear plastic resin had been added to the upper portion of the toneholes.... My clarinet had no real intonation issues beforehand. Any reason for this? ever heard of this happening?

It was probably done to seal open pores in the wood to make it more airtight.

I know Peter Spriggs used to do this routinely with overhauls.

You'll see this on the top model Yamaha clarinets, oboes and piccolos as well. Bassoons usually have their bedplaces varnished to seal them and make them impervious to moisture.
It's a routine thing at Howarth when recutting bedplaces prior to finishing instruments (on oboes and clarinets) to coat them with a thin layer of superglue, then sprinkle wood dust onto the superglue and then recut them to get a perfect bedplace in order to seat cork pads onto.
The superglue fills any open vessels or pores and the wood dust fills any minor surface chips or imperfections from the initial cutting. Even badly chipped or damaged bedplaces can be repaired by building up with more applications of superglue and wood dust, and then recut with the correct size cutter.

There's that superglue again Chris !!
I just did an overhaul where when I played it leaked. When I pressed firmly with my fingers it leaked less. When I put it on a MAG machine and plugged the toneholes with rubber plugs it was an 8 (wide open leak) out of 8. had to seal the toneholes and viola .. 0.2 out of 8
sometimes sealing the toneholes is needed

Hi Kev, I don’t know what material my tech uses but I know a major part of an overhaul, or fixing a leak if the pad is not the problem, is filling in the tiny little holes and cracks in the pores of the wood. Not only does he do it on the top of the tone hole where the pad makes contact but inside the tone hole if necessary. I’ve never noticed it because he makes it blend into the wood but I’ve seen him do it and he’s explained it to me many times when I pick up my horns. That’s one of the good signs of a good repairman. When people get a “cheap” job done it’s often because all that was done was pad replacement and what is obvious instead of a thorough examination of the entire clarinet.
