Dullcote on canopies

if you can't get it off of there, and you probably can't, you can minimize the damage by polishing with toothpaste, cleaning it thoroughly, and dipping it in Future (Pledge)

If you dip it and it isn't clear enough, just strip the Future off with Windex, polish some more, and dip it again

If this is a warplane, remember that those canopies sometimes had swirls in them right after being polished by a ground crewman, and could/did take on a milky looking effect in certain light reflections

so, you can get it pretty good, and stop there and call it weathered (a lot of people pile on the weathering and give us a crystal clear canopy to look at,,,,,which wouldn't be realistic)

Just some thoughts that I hope are of help

Several years back a kit had some sort of coating on the canopy from the manufacturer, it was sprayed on and looked awful, lots of orange peel on one side. I imagine it was supposed to make the canopy look really clear. No cleaner was effective at removal, so I just started sanding through to the plastic.

I started with wet, well used 600 grit, when all of the material was gone I started sanding with finer grades, ending up with 12,000. Final polish with Novus left it looking really good, then a dip in future. Just enough of the framing was left to allow masking. If you're concerned about losing the framing details, you could lightly score beside them for masking locations. If the framing is not raised, you're home free.

You can always  eject. Ha! Mike

If it is an older plane, like ww2, the canopy plastic was not well stabilized against UV, and went dull pretty quick.  If it is a heavily weathered bird, just coat the rest of the canopy :-)

Or make it a bird parked at AMARC.   :-)

Try some micromesh sandpaper. I've had luck with blemishes on canopies using 6000, 8000 and 12000 micromesh.

I've used denatured alcohol in the past for just that issue, and it worked well

Try soaking in Pine-Sol for a while and then scrubbing with a swab or rag.  

We used to have to sand and polish with ridiculous high number grits to polish a canopy.  Now, just a coarse sand with about 600 or 1000 to remove the dullcoat, and then a coat of Future.  Future is a real boon to working with transparencies.

Goo Gone should take it off with no problem.  I'm guessing it's already on the plane, so just apply it carefully with a small cotton swab (like the kind Tamiya makes).
