Removing scratches from perspex???
Morning.
Have a piece of perspex sat here awaiting some graphics. It was an existing sign that had frosted vinyl on the rear (much like Phil’s in his demo)
Upon removing the frosted & applying orange vinyl in its place, I am now aware of loads of scratches all over the face that are now highlighted by the orange but were masked b the frosted 😕
Any idea how to remove these? Is T-cut too harsh for perspex, as window cleaner (cream) has done nowt.
Replacement of the panel is not an option at this stage.
Cheers,
G.

Would putting the orange over the frosted be an option?
T-Cut should be ok after all, it’s made for cars and doesn’t scratch them!

Gwarred,
T cut should be OK. I have used this method before to remove very light scratches from clear cast perspex sheet. My advice would be if you are not sure then experiment on a small off cut first if you have one. -
It is dealt with on one of the videos here https://www.uksignboards.com/viewtopic.p … highlight=

You could try the links I posted for removing screen scratches, the products do work very well but it’s not a cheap option.

We used to use duraglit but again it only really worked with light scratches

Hi
We have used ‘Brasso’ for this with good success… Probably similar to T-Cut.
Use loads of the brass to ‘scratch’ down as deep as the deepest mark, then polish with a soft cloth to make the perspex shiny again.Practice on a piece of acrylic first please…

T_Cut is pretty course so add some water – or even try toothpaste.
May sound stupid but I have used it with water in the past and removed scratches.Always cleans the bug sh*te off me windscreen nicely and it’s minty… :lol1:

G3 and water is a lot less effort than T-cut. You can actually electric mop Perspex/acrylics as you would a car or van when the paints flat/bad, just don’t push too hard or get it too hot.

Jewellers Rouge. I got a small tub many years ago for polishing out fine scratches in brass. CAn be mixed with brasso, water etc as its a very fine abrasive polishing compound.
Quich search found it here

Cheers for all the replies guys. I’ve had the electric buffer whizzing round on it for about 10 mins now with T-cut, & whilst some of them have gone, the rest are just too deep to get without a proper buffer wheel.
I think it’s been used as a sledge at some point 😕
Hopefully most of the graphics will cover them up 😉

if the scratches are deep, then use some 1200 wet n dry sandpaper, with lots of water and sand them out, then buff up with G3, perfect.
