Removing Shadowing in Lexan? Possible?

[ScottyAdams]

Hey Guys,

We are redoing a backlit panel sign. The piece that we removed is still in pretty good shape but seems to have some yellowing obviously from the sun and has created some shadowing. Before I remove all the old vinyl, is there any way to get rid of the shadowing or should we just order a new panel? If there is a way to sort of polish it out or something else, this would save us a decent amount of money considering the sign is about 12 ft long. Any help would be greatly appreciated.

oh and the The substrate is a polycarbonate or Lexan material

the labor associated with trying to remove ghosting from lexan will make it so that you WONT save any, and will most likely lose money as opposed to just buying a fresh piece of plastic...

That's what happens with Lexan after time ... It yellows ... I have never heard of being able to remove that.

Thats what I figured...Thanks for the help.

Do yourself and the customer a favor and just buy new.
Love...Jill

I have advised clients against reusing lexan panels. Even after they were up after a short preiod.
In fact it only takes a few months the ghosts will appear. I have panels that were reused and not a single ghost was showing. Now it is so obvious where the old lettering was. The plastic continued to change appearance over time and now the ghosts are showing. What a distraction.

full-size digital print?
fresh vinyl is white, and covers up the ghosting.

Comet does a pretty good job and so does Rapid Remover.

Depending on if its a pan face for flat face and the budget, would really determine if its worth it to buy new or clean as good as you can.
