Anyone know the best way to polish scratches out of clear acrylic?

Thanks,
David

Hi

Very fine wet and dry followed by toothpaste then Brasso.

Or one of the proprietory brands.

When we are polishing scratches out of aircraft windscreens we use a kit called micromesh,they are very fine abrasive cloths going down in grades(also good for polishing CDs ) not sure if you can get them out of the industry or prices ect but works really well. Lewis.

Here you go this is the product & how to use

There is a very good product called PlastX which has polished out some fairly deep scratches on plastic headlights. Available in Halfrauds I believe

what about getting them out of grp? will these do the job?

I think there is a special polish for grp I think it was mentioned a few weeks ago,not sure of name sorry.

Whitening toothpaste can work quite well at removing scratches, but won’t leave you a clear finish, more foggy... Tcut also works. You can finish with good quality car polish, will give you back the clear shine but will take some time.

If you only want to do a small area or work out a particularly deep scratch put a piece of soft balsa dowel (the softer the better!) in a small drill and use that dipped in something like toothpaste. Sounds odd but you wouldn’t believe the results. We used to use a similar method using balsa and diamond paste to polish hard chrome plating to a PERFECT finish for use on coining dies.

And in case you were wandering, I believe it’s very finely powdered glass they put into toothpaste to give it that whitening “quality”

Thanks guys, will look at some of the options.

Its to polish up the cover for my new record deck. Which isnt bad, just has 20yrs of fine scratches.

We tried some of Autosol Scratch Remover plastic glas, lacquer surfaces on eBay (end time 24-Feb-11 20:10:45 GMT) when someone managed to put a couple of scratches on the black plastic base of our new tv. Really pleased with how it worked. No sign of the scratches and left a really glossy finish.

i polished out a scratch from a motorcycle helmet visor once (visor no longer avable)
i used g4 compound and a soft wheel on a dremel thing
worked wounders could not see it form inside or out
