SOLARTEX: poly/varnish clear coat update info from Solarfilm Co.

I received this reply from Andrew at Solarfilm Co. UK in regards to the use of polyurethane or varnish for a clear coat on Solartex.

Glad you like using Solartex, the info on the website may have been taken from the older Solartex instruction sheet. In the early days varnishes and some polyurethanes were not compatible with our resins. We had modellers varnish their models then complained when it started to flake off. Things have moved on, there is more choice and our resins have slightly changed making everything more compatible, as you have found. The newer Satin Solartex (Blue, old one was Orange) instruction sheet mentions a lot about our Clearcoat and Solarlac paints (probably impossible to find in Canada) which were developed for Solartex and our other products. At the end it states; "Before using any paint or coating (other than Clearcoat or Solarlac) always satisfy yourself by tests on scrap pieces that it is compatible with Solartex." A model aircraft is always moving through expansion/contraction or the stresses of flying. Solartex when correctly applied will retain its elasticity which moves with the airframe, any paint also must move with the covering. The old varnishes etc. once completely dry would become brittle, and then craze and let fuel under and the model started looking shabby. This may be due to the varnishes were meant for use on rigid furniture or the glow fuel used may have accelerated the failure of the varnish/polyurethane. Solartex is fuel proof on its own, it can get a little dirty, so before every trip to the flying field prepare a spray/squeeze bottle of hot (hot so is cooler by the end of your first flight) water with a few of drops of washing up liquid added. After each flight all fuel spills and exhaust spray should be washed off with the squeeze bottle of now warm soapy water. Especially when the model is to be stored after a weekends flying. It is the fuel residue left on the model after flying when the model is stored that does the most damage, it will slowly leach into the surface over time, this causes the surface to swell slightly and becomes sticky as the esters in the fuel evaporate, this attracts more dirt and then the model starts to look shabby.

I hope this helps
