Update and disclaimer - Early in the project, it was decided to install mylar, so I proceeded with the touch ups and leveling etc. The mylar was ordered from the USA, got lost in transit and I had to wait until the insurance went through etc etc. All the warnings were already there in front of me - "Do not install mylar on this playfield.."
So I prepared the playfield and it took 45 minutes to install the mylar and it went on perfectly except for a small crease near the spinner (which makes no sense), as can be seen in the photos below ;
Happy that it was installed correctly, and it was as smooth as glass, I went off to do some other work and returned 2 hours later to see this ;
Horrified, I thought I'd let it settle and then straighten it the following day. The next day, it was even worse, and was deteriorating every hour. The lifting and creases were increasing in size !
I called up Gavin, as I needed a second opinion. His idea was to remove it asap before the adhesive sets. So I did - and it look 15 minutes.
You can see the mylar is simply rubbish. Now this is "supposed" to be the best on the market. Never again !
Morale of the story and lesson learnt - I've applied mylar on over 20 games without a single issue. "Mylar" these days is NOT the same as it was 10 years ago. APR will NEVER install mylar on a playfield. The best place for mylar is .. in the bin !
Right - So after cleaning up the residue - which took minutes as the adhesive was rubbish - we have decided to clearcoat the playfield professionally ! This will be great opportunity to see how an EM plays with a clearcoat !
So in the end, no damage done, and a lesson learned. I've currently prepared the playfield and it will be clearcoated in the next 2 weeks.
