It might be a matter of time, but unless its bullet proof its prudent to back off. There is definitely something wrong with the end result not being durable. The last thing I want to do is produce something that doesn't last many years & durable to pinball use or abuse. I will keep looking into it but it looks like I will have to wait on my main printer getting new equipment in a year or two.
On the positive side I can focus on playfield restorations & getting through the backlog. Prove that it is an affordable alternative for those that can't personally fix up or touch up their playfields. Thanks guys for your positive support!
