Can clear resin canopies be polished?

Hello,

I was just wondering if clear resin canopies could be polished? I have a piece that has some sort of blemish on top and I was wondering if I could go the route that Dave Aungst took with his recent build report of his extraordinary F-106B here on Hyperscale. He did a great job with that F-106B canopy (granted it was injection molded plastic).

So I was wondering if I could do the same with clear resin canopy?

Thanks in advance

Clear resin is an Aliphatic Urethane in composition.
Which means "Do Not" use anything to polish that type of urethane that contains alcohol. Alcohol attack and hazes Aliphatic urethanes.

We have wet sanded and polished clear resin parts her at the office with Meguirs automotive products.
Doesn't hurt to dip the resin part in Future afterwards to enhance the clarity.

Scott will Future stick to the resin well enough that enamel paint can be applied and masked over?

I presume the answer is yes but i've never painted a resin canopy before.

on both sides...

The one thing to remember is all silicone's leach a little siloxane onto each and every rein part. That's how silicone works until it dries out. So unless you find a way to completely strip and siloxane off of the canopy the Future will more than likely fisheye.

Lightly sanding both side with 1000 or higher grit then Windex wipe it a couple of times should do it.. We have not had Future come off of our resin parts here at the office. And I have done some pretty rigorous taping on some of them.
Also make sure none of the polishing wax compound does not leave a greasy film before future.. In fact you may not even need to polish if you are going to use a future wax dip.

of using 600 -> 800 -> 1000 -> 1200 -> 1500 grit sandpaper followed by Tamiya Polishing Compounds

And then followed by Future.

The MicroMesh system is what we use here.

I also purchased this:

https://hlj.com/product/AASAPA-2000

Looked through my box of tricks ( aka box where I throw all my modeling tools) and found it.

It has grits of 3200, 3600, 4000, 6000, 8000, and 12000.
