Just a quick word of warning having done this so many times ,,, both methods can work but both methods if they cause any issues can peel off easily but when you get to an insert takIng the insert decals out,, get a cheap plastic thick Stanley knife with the blade at full length and I do a sawing action under through the glue between the play field and Mylar whilst freezing or hair drying.. surgical spirit from the chemist is my glue removal method .. just the clear stuff not surgical with added oilI will do it for u if you can wait
Be easier and cheaper to get a new playfield than get hold of flourI’ve done both freeze and hot air methods before and had good results with both. My general rule is freeze for diamond plate and newer play fields and hot air for the older stuff. Then use the flour method to get the glue off
Don't pay for freeze spray, get air duster and use upside down.
Yes a large tin can is nearly 18 quid as I remember but it’s worth every penny if not using it pulls inserts decals out , I’ve spent 50quid doing just one play field before now. Some just don’t seem to want to part with their Mylar
