Poly paint

I am considering buying a second hand glider that was recently =
refinished
with poly paint as opposed to gel coat. What is poly paint? What are the
pros and cons of poly paint compared to gel coat?

Miguel

as long as the surface below was properly prepared.. should be ok.. that is
the standard for replacing old gel coats.. sand it down.. re profile the
wing.. and paint it..

I think that Miguel was asking the difference between gel coat and
poliurethane paint.
Anyway I don't have enough knowledge about the matter to explain it!

Hi Miguel,
I used to own a Sportvega which was finished in a polyurethane paint. As
I understand the explanations at the time, the polyurethane finish is
softer, more elastic and cheaper to re-do. At around that time the BGA
DG 500 went to some astronomical height above Aboyne, in Scotland. I was
told that the extremes of temperature to which it was exposed and,
possibly, the rapidity of temperature change on ascent and descent,
resulted in extensive gel coat cracking; and that the polyurethane
finish on my rather ancient Sportvega would not have been similarly
affected. Lastly, if you do the prep work, a reasonable garage could
respray the glider for you at much less expense than the usual aviation
prices.

Hi Miguel,
There are two "Poly" paints used on sailplanes, Polyeurathane and Acrylic
Urathane. I just repainted my Genesis 2 with Acrylic Urathane and found it very
easy to work with. Preped the non-damaged areas by contouring with 60 grit,
followed by 220 and then paint with 3 medium coats. Wet sandad with 600wet and
800wet, then wool buffer and liquid rubbing compound.
The Genesis 2 and LAK -17 are painted with Acrylic Urathane by the
manufacturer. The only down-side that I am aware of, is the softer paint
(urathane) may blister more quickly, if left too long in a wet trailer

Actually the choice of paint is an option (at least on the LAK-17).
Ours is painted in painted with polyurethane. For $400 more we could
have had it painted in acrylic urethane, but we couldn't find anyone who
would say flat out it was worth the extra money. They also give you the
option of the ugly (but apparently bulletproof) epoxy paint that was
standard on the earlier LAKs...

I would stay away from the epoxy paint because it yellows very rapidly and one
ends up with a ship the color of urine.

BTW, I have the color of the Acrylic Urathane used on the Genesis 2. It is;
Toyota 040/HP

If it were now they would have been able to get them
finished in PU by the factory.
