[Public-list] Lexan or Acrylic ?

[Gary Barker]

I chose lexan for the ports on my A30 because of their large size. It has
yellowed
over the 8 years since they were installed, but since I chose a dark tint,
it is not so noticeable.
It has been very resistant to scratches, but we are careful with what we use
to clean them.
I would choose acrylic for the smaller ports.

Hi Guys.
We are having a great debate regarding the best material for port-light
replacement on the Alberg 22 Newsgroup.
Some say Lexan, some, including me, say Acrylic.
I redid my port-lights using 3/8" Acrylic 5 years ago and here are my
reasons
for choosing this material.
For it's great strength, I considered using Lexan for my port-lights on
Elusive, but
decided against it for the following reasons.
1) Alberg 22 ports do not cover a large in area so the high strength
     of Lexan is of less importance
2) Lexan does scratch easier than Acrylic.
3) Scratches that do occur in Acrylic can be polished out.
4) Lexan has a limited life in the sun and will yellow, yellowed Acrylic
      can be rejuvenated.
Some AL22 have have their port-lights mounted on the outside of the
cabin sides, without bezels. I would be more inclined to use Lexan in
these cases.
Lexan drills very well as opposed to Acrylic which chips easily and
will usually
crack at the drill hole.
Anyone want to jump in on this?
