whitening a polycarb sign face

[rfsign]

I am stripping the vinyl off some large sign polycarb faces and I am going to apply new vinyl. Anyone have a technique to either polish the face to match what was under the vinyl or to discolour what was under the vinyl to match the exposed part of the face?

yup, buy new faces. Seriously, I've never been able to get them looking new again, plus the amount of labour involved is most likely more than the cost of new faces.

it will never be new again, but soft scrub and lots of elbow grease will help some.

Leave them for your customer to clean....
He will buy new ones.

Time is money. It is more cost effective for your customer to buy new faces. Its is your job to educate them into the correct decision. If they want new looking faces, they will need to be new!

only 1 side is UV coated,so that is a bad idea.

"greased lightening". I buy it at sams club by the gallon for $17. I've also seen it at autozone.
