illuminated sign covered with calendered vinyl?

[0igo]

so i have a client that has a plastic board that has turned "yellow" due to long time in the sun.i was thinking about covering the whole thing with white calendared vinyl and place other vinyl on top of it. do you think this is a good idea? will light still be able to shine through it at night or not?

example of the sign (not actual sign)

Time for a new panel. Just went through this with a client that brought me panels to reuse. Told him I won't reuse old panels because they could fail. As he walked past his truck he bumped a corner with his hand and a big chunhk of the panel fell off. He told me to get new ones.

Need new panels cal vinyl will look bad and block all light. It will just wind up being something you replace again in 6 months cause it fails as well, I would sell the customer on new substrate or don't take the job.

A translucent sheet of acrylic or polycarb will stop about 15% to 20% of light from going through. Only clear will allow 100% to pass. Add the yellowing and it's down another 5% or so. If you added translucent white, you'd be adding about 30%. So, you'd be near only 50% to 40% light coming through anymore. Use your specs with calendared and you'd stop almost all of the light from coming through. Basically, you would no longer have a backlit sign.

Like mentioned, time for a new piece of material.

I agree with what everyone said, it's foolish to try and use the customers existing panels
just because they're wanting to save a couple bucks, it looks like crap and if it's brittle
and cracks you're stuck with the cost of replacing it.

Also,FYI, Polycarbonate tends to turn yellow much quicker than acrylic.
