The original hardtop I recently acquired for the 3A has a perspex rear lite. It is a bit foggy but I have been told this material can be restored or at least renewed for better transparency. I have heard everything from toothpaste to expensive commercial polishing kits. Any suggestions? /bcforum/images/%%GRAEMLIN_URL%%/smile.gif

Novus make a 3-stage plastic polish that will probably make yours (almost) like new. #3 is the gritiest for removing deep scratches so you might just want to start with #2. A good washing with lots of soapy water is where I'd start first.

I have a 3A hardtop in my loft too but the window is fairly clear. You've got a long way to go on that one!
 
Micro-Mesh is a set of abrasives. The kit contains several steps from coarse to fine. It's used on plexiglass aircraft windscreens. I think Sporty's Pilot Shop sells it. It requires elbow grease, available locally.
 
if its opaque all the way thru,its pretty much toast. I have done several plexiglass pieces.They can be brought back pretty well.Notice I didnt say perspex,I'm having a I hate England day, any way If you know a good paint wheel man have him work it with a wool buff pad on his machine,with the right compounds. He will know which ones. Doing it by hand will make your arm fall off.Or bring it over and I'll give it a shot.
( Dont ya love free offers of help from guys who know ya cant make it here)
 
Cee Baileys make air craft windshields and sells some stuff to refinish things like this. i did it on my motorcycle windshield. Good look and just keep saying , I am having fun, as your arm falls off.
 
I recently bought a product called 'Five Minute Headlight Restorer' at Autozone for about $13.00. It made ten year old hazy plastic headlights look like new. It has a small pad with an abrasive that attaches to a low speed drill. All you do is spray on water, and work the pad over the area. For the price, it might be worth trying. David K.
 
Hello Frank,

you could try metal polish on a small area to see if it will come clear, before spending any money on a more effective abrasive system. I think you will quickly find out if it is restoreable or not?

first get a buffer, what ever you can afford. (i have air tools and air buffers & compressor-the best way to go)
get some Maguires plastic polish and go to it. Forget about trying to do it by hand-waste of time. You'll just get sore arms, get frustrated, and either give up and take it to someone, or buy the buffer anyways after much pain. I don't like pain.
