Recovering clear window parts

[wavodavo]

Hello,

I need some help to see if I can recover my clear window. I had to remove some paint off of it and used some Deluxe Brush Magic as its great and had no problems before. As I was taking off the paint, the Brush Magic was starting to harden and got even worse when I tried to wash it off. Now I don't know if the plastic has reacted to or not or whether it's still the brush magic on there. I've tried to polish out but has not made any difference. I've used fine grit, glass polish cleaner, toothpaste and Klear.

Any advice would be great thanks

Dave

I would use something like 400 grit sandpaper then gradually work down to 1000 or so. It will be time consuming but you will need to remove the roughness and you won't be able to do that with fine grit sandpaper to start off with. If you have Tamiya polishing compound I would use this once you've polished out the damage and it should bring it up like new. Good luck if you haven't already fixed it.

Micromesh is the product you need.  Absolute clearing marks off glass.

What does the clear plastic feel like? Is it rought or smooth?

In any event, the key to using abrasives is to step from some grit that's consistent with the current surface and then use finer and finer grits. For clear plastic, you want to go to like 12000 and then use a burnisher. If you start with too fine a grit compared to the current surface condition, you won't be able to get a good finish.
