Crazed windows

snowleopard & tudorsailor,

Seateach chandlery at Emsworth, Hants has a large stock of Lewmar hatches.

Funny you should say that - that's where they came from in the first place but I don't plan on replacing the hatches just because they're crazed.

Thanks Akyaka, but the sign companys I tried don't do stuff thick enough for me, I want to glaze the fore hatch and set solar panels under it so it may be stood on or fallen on, and sign companys are few and far between in the west if Ireland.
 
You can remove some of the surface crazing by using very fine sandpaper then polishing, very tedious and tends to remove it only for a year or two then it will return, if you check polish for restoring plastic on cars , this can be used or lens polishers for glasses.

Sandpaper is for wood. Wet and Dry paper about 600-800 grit use plenty of water and a flat block although acrylic is very difficult to acheive a high polished surface second time around, dont as suggested put a blow torch to it as mentioned before you could try some of the autosol cremes and a power mop. Why not replace with some nice tinted acrylic. Good luck.
 
is wet n dry not sand paper....... and it would be more like a quick rub with 600 then 1200-1500

No------ sand paper glass paper silicon carbide paper garnet paper used on wood and wood products wet n dry for plastics, thermosetting, and metals you could even go up to 1800 grit if you have the time. But if someone wishes to use sandpaper on acrylic who am I to stop them. Incidently rather than use water with wet n dry some clean engine oil acts as good lubricant when polishing plastic, and finish with metal polish.
