67 dash bezel

I bought a heat gun and was able to get the warps out, it worked very well- I'm not sure if you can see it in the pics, the primer shot is the after.

Once in primer there were scratches and a few gouged out areas which I filled and sanded. That is where the problem started. Every time I sanded and primered, the new primer would bubble up along the places where the old primer ended and the plastic began.
I'm not a complete fool, I would clean it and make sure it was completely dry before primering again, but the same issue every time. I've painted a few cars completely by myself and never had an issue like this. It started to look messy and uneven; and I was wet sanding with very fine paper so the final coat would be nice and smooth.
Well, I figured I would start over, and the Easy Off would not remove the primer so I bought a paint remover safe for plastics, tested it in a small area on the back, then on the front- no issues. Once you hit it with cold water it neutralized it. So with the bezel in the sink, I hit it with the remover and then immediately rinsed it off. It looked really good, the plastic was even white, not a yellow tone like before.

I came back a few minutes later and the whole bezel looked like it had a case of elephantitus! It is completely destroyed, the letters practically bubbled off and it cracked right down the whole thing on the left side. Done!
