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? Regards Miguel |

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.

What is poly paint? What are the
pros and cons of poly paint compared to gel coat? 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 JJ Sinclair |

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... Marc |
