clear Perspex scratches

[Pvapour]

managed to get some scratches on the clock cluster of one of my motorcycles, can you polish them out with the same methods as for bodywork? or am I best leaving alone?

You can polish out perspex glass scratches, but be careful. I would use something like Meguiar's Mirror Glaze #17 Clear Plastic Cleaner. Only costs around £7 but will work wonders.

thanks bellair, will go steady...

Be very gentle. I would go with some Displex, used for polishing the plastic lenses over LCD displays (phones, iPods etc). Can be had from Ebay for £2.85.

I tried to polish a scratch out from perspex over a dial cluster in a car once. I found that the surface of the perspex did not take kindly to polishing at all, as if it had an anti-reflective coating. Actually made it worse.

You could try PolyWatch.

About £5 for a tube (fairly small). as the name suggested, for use on watches and pretty gentle.

Hi, I have polycarb windows which have some slight marks & swirls - I am very nervous about making them worse, but would like to get them as mark free as possible.... but dont want to make an arse of it; would any of the products or advice above work for me or has anyone any other advice/methods out there? cheers, Mark

Fast Cut Plus on a Lake Country CCS Yellow Cutting pad followed by Menzerna 106FF Final Finish restored the clarity and removed all but the much deeper marks

just be careful as some perspex have treatment layer on, worth talking to manufacturer if you are unsure (and/or getting a pro detailer in)

Be very careful if machining them, stick to LOW speeds only and mild compound/pads, keep heat to a minimum.

I fecked a polycarb window this way. Got the trusty rotary out, bored with lack of progress so wound it up to usual swirlbusting speeds and it literally melted the polycarb. Live and learn, so learn by my mistake. SLOOOOWWW speeds and patience

Brasso if it is acrylic/Perspex.

Have you done this yourself? I'd expext Brasso to be too aggressive. I had plastic windows on my MK1 RS2000 back when I was 18 and I just used to mop them with fine compound every few months. Obviously you need to exercise a degree of care, they will melt if you get them hot, but I never had any problems.

Not on a vehicle, but I have polished a fair bit of Perspex with Brasso. Like any similar compound, take it easy. When using anything like that I always remember the lad I used to live next to, who liked T-Cutting his first car (a Fiesta) every few months. You can guess what the result was.
