=rizla=

Greygate plastic polish is quite good.

I have some 12,000 and 24,000 grit emery cloth kicking around which I got from an army chum. It's the stuff used for polishing minor abrasions out of Tornado and Eurofighter cockpit canopies.

Well, I take that back then!


The finest emery paper I have used was 1200 grit, and that is so smooth you can hardly feel any texture - I've used it on fibreglass and after 1200 it was ready for compounding. 24000 grit must be like glass. Every day's a schoolday.

An army chum with access to specialised RAF kit?

It's difficult to polish plastic and get a good result - there are specially designed products for this purpose. I find this stuff works well:

Yes. he was attached to a unit on an RAF base in Wales looking after RE kit. The emery cloth was acquired from the RAF workshops for the purpose of polishing out scratches on plastic elements of some of the vehicles the unit looked after.


As it turned out, the RE were better at scratching stuff than the cloth was at polishing, so it sat on a shelf. QM wouldn't take it back as it was such low value it wasn't worth booking it back in.


It's also not exactly 'specialised kit'. You can buy it online, on Amazon, eBay and others.


After looking at the link below, I went out and checked the garage and I have to correct my earlier statement - the 24000 grit stuff isn't 24000, its 2400 non-cushioned. The 12000 is as supplied below:

Hi

I know this may not be the best place to ask but does anyone know what can I use to remove a scratch from a plastic brake light?

It isn't a deep one so I don't want to start sanding it down

Thanks

Use 1000, then 1500, 2000, 2500, 3000 grade wet and dry. Use it wet with a little washing-up liquid in the water. As you progress to the finer grades, rub at right-angles to the grade you used prviously. Then finsh with G3.

Look up YouTube videos on restoring plastic headlights if you're not sure what to do.
