BL thread is about to expire so pasting copy of that post here.
Interesting. I heard of certain acrylic liquids that can fix some parts condition
like scratches and such.
I also decided to buy fairly worn parts from seller to fix to fix it up see if
I can get it to great condition as possible.
Note: This is NO reflection upon seller I bought those from. He exactly noted
what condition it was and I got exactly what I expected.
The windows was in decent but worn condition, at "raw" one is decent condition
and other 2 had been bit discolored and somewhat "sandpapered" as you can see
effect on paper behind it. There is also couple heavier than fixable scratches.
After I used metal polish, then removed as much polish as I can and cleaned it,
condition of parts was much improved. there was lot of micro-scratches after
it but usable condition. Lot of discolor went away and pretty lot of "sandpapered"
look went away too. Light reflection is worse I could get it to show up. (I wish
I took better picture of that as by time I thought of it, I already dropped it
into next step)
The plate was in decent but well used condition, but I cannot polish it due to
number of studs and difficulty on wiping polish off afterwards. Brasso probably
will do better as it's more cleanable. After I left windows and plate in floor
polish solution for couple minutes and dried it in few steps (very carefully
as dust or fingerprint could mar it!) on wax baking paper. When it was dry enough
(around 3 minutes) I got paper and dropped parts on it from inches off to shake
off droplets. After 10 minutes I flipped it to other side and let it dry for
other 10 minutes. Novus is recommended by other people but I used pledge floor
polish which is also acrylic liquid.
As you can see, results is pretty decent. You can see quite a bit of micro-scratches
and few remaining deeper scratches. However, this liquid has altered refraction
so it is not really visible when held in room without light refection or held
up with light shining though it to your eyes. This is small improvement after
Notes on this:
1: If I ever decided to sell those (yeah right!) or any other parts done like
this, I would disclose it.
2: Floor polish step is easy to make mistakes on. If there is dirt, it will be
under very thin coating so it cannot be removed without metal polishing all way
down again. Very good cleaning is recommended! You can only touch parts of part
drying in this coating where you don't care what those parts looks like. I used
sides of windows and plate.
3: Second step of floor polish (or Novus) really isn't very necessary unless
transparent color cannot be polished via metal polish. Plate was massively helped
