I have a Lewmar hatch on my Konsort which is badly crazed or at least I thought it was. The outer surface is crazed but when I stripped it down today I realised they are only very shalow. Can they be polished out? the material is 12mm thick so it shouldn't affect the strength of the hatch
 
Personally I wouldn't bother trying to polish crazing out. I doubt you'd be able to get a satisfactory result and even if you do you'll have reduced the thickness and strength. Get replacement acrylic or use someone like http://www.seaclear.co.uk/page4.html to do the job for you.

Edit just noticed you're north of the border. There must be someone nearer to you than Seaclear.

Seateach at Emsworth, Hants do Lewmar hatches at good prices, but if ordering by mail order be absolutely clear on hatch size and bolt spacing, this is not their strong point; guess how I and my chums know this ?!
 
QD plastics Dumbarton

Try QD plastics 01389 762377 they are in Dumbarton. Take your hatch to them and they will sort you out. We have used them to replace hatches on our last 3 boats. They are quite busy so might take a couple of weeks but sensible prices unlike others that have been recommended.

Another vote for QD

I always find it comforting when a company are so busy your request takes its place in the queue...
 
Just for info.When I had the survey done whilst buying my boat,I talked to the surveyor about the crazed Lewmar hatch.He said that he had always noted such surface crazing as needing replacement.However he had one day taken an old crazed hatch home and tried to break it with a sledge hammer.He failed after many attempts.Now he notes the crazing generally as being cosmetic.
 
Thanks for the replies guys. I know QD Plastics, as said just down the road. I just feel that at 12mm thick and with micro crazing on the top I should be able to polish them out. They certainly won't affect the strength. Any thief that tries to break in that way thinking it would be easy is in for a big surprise. Time to get the brasso out I think. Nothing ventures nothing gained as they say.

I don't think you will do much with brasso I tried some tcut on mine but it made no diffenece I think you would need some sort of sande,r finish with very fine paper then polish with tcut. You might end up with a nice frosted effect ;)
 
I recently polished out a lot of crazing on some bench grinder eye-guards using 600 wet+dry paper, 2000 w&d paper followed by solvol autosol.
Very effective, quick and easy.
Probably better to use farecla than autosol, which is meant for polishing metal, I'm told the oil in it can cause discolouration, don't know about that but it sounds plausible?
A coat of wax after should give a bit off UV protection.

I'd say it was worth a try.
