I had some bubbling on my F14. Ended up removing the entire playfield mylar, cleaning, then putting new down. It was my first job so a little rough around the edges, but a vast improvement from purchase condition.

I'm going to attempt a mylar job similar to yours soon. I was thinking about using that tacky spray can stuff from Michael's. I've got a large piece "missing" (a wear hole) with rough edges, and it's peeling up. I'll cut close to where it is still intact, lift and spray some tacky stuff, try to squeegy it flat, then use something heavy to keep it down overnight. Probably won't work, but worth a try.

Good luck!

Oh yeah, it was a LONG process. Like you, probably up to 8 hours all told. Glad I did it though.

Like I said, far better than how I received it.

Haha, yeah, there's that.
Like I said, just a thought. Haven't really put too much into it yet.

Great idea!

I'd be interested in your progress OP. The more knowledge we gain, the better.
