Bob, Thanks for your detailed insights. What are your thoughts on the affects of a fiberglass trailer painted with regular ol' paint instead of gel coat. Does any UV make it through the trailer to affect the glider within? TIA. I don't know whether the UV will make it into the trailer. However, I do know that the UV will destroy the "regular old paint" rather quickly. In another life, I owned a wooden boat which was on the water the whole year without a cover. The UV literally burnt the whole paint away within two years. And this wasn't "regular old paint", but specialized UV resistant boat varnish. Stefan |

be published somewhere? The technical paper is scheduled to be published at an industry conference next October. However, I'll be happy to make the SSA presentation available when it's complete. Bob |

Great discussion Bob....thanks! Any chance that your convention talk will
be published somewhere? Will be happy to share convention presentation when finished. The formal technical paper will be presented at a technical conference on October. Bob, Thanks for your detailed insights. What are your thoughts on the affects of a fiberglass trailer painted with regular ol' paint instead of gel coat. Does any UV make it through the trailer to affect the glider within? TIA. If the regular ol' paint happens to be urethane it is not much different from gel coat - almost all white coatings use TiO2 pigment, so the inherent UV penetration is not an issue. Of course there is a wide range of photo-aging performance with various types of paints. One difference between gel coat and paint is the thickness. Because a paint film is typically thinner than gel coat it will allow more long-wave penetration (not harmful to polymer surfaces), but may allow more solar heating inside a trailer. I've never seen any actual data describing the difference, so don't know how significant the delta might be. Bob |
