I would not recommend painting the cabinet just around the perimeter like that. The decals are translucent and you will see that bleed through from behind.

Been following Ricochets progress on the IJ Mode fix and admire his perseverance! The man is on a mission! But it wasn't in time for my IJ restoration and I went ahead and put it all together and while playing it I was frustrated as hell when the ball kept bouncing out of that damn mode hole. I knew I had some of those Pinball Heaven brackets somewhere and I finally found them! So now I had a decision, wait for Ricochet's fix or try the Pinball Heaven bracket. So here's what I did. Just to experiment, I took the original bracket and drilled a hole and mounted a rubber on it, the black one pictured. But when I compared them to the P.H bracket, I could see that it's angled differently and I thought when the ball hit it, it would reflect downward. I read in another thread to elongate the 3 holes to move it back more, so that's what I did. I've been playing the shit out of it all week and the ball goes in every time now. So I'm putting my mini playfield back in and calling this done!

This I.J is sold but I'm actually restoring another one for my personal collection. So now my dilemma is should I wait for Ricochet's fix or use another P.H bracket! Anyway took a few pics to see if they help people understand the geometry of the old bracket as compared to the P.H bracket. You can also notice how the P.H bracket has an offset bend to sort of step it back a bit. Not sure what I'm going to do yet, but I am looking forward to seeing Ricochet's final design!

You can try with the "allow dim illumination" setting turned off and see if that helps. Other than that I would start at the transformer and make sure the GI connector isn't all toasty looking and overheated. Then a trip to the backbox to check the 2 GI plugs on the lower left of the power driver PCB.

I think the mix that hep uses has a few advantages. One is, less die-back. He seems to be able to clear and polish and start reassembly with much less wait time. I think his clear formula is also much harder and he goes out of his way not to put it on too thick. When I first started using Spraymax I made the mistake of putting it on too thick, combined with not waiting long enough for cure time and die-back.

Or you could try these other versions that don't have the pop up:
