Lozenge mounting update - lessons learned.
1) Minwax has its advantages. After first dismissing Minwax, I've done a 180 and think it is the best solution for adhering the lozenge sheets. I'd made up a test portion of wing and experimented with Minwax, white glue diluted and dope. Initially, I thought the dope was the best since it gave a quick and firm seal of the transfer to the underlying airframe. Additional work however showed that Minwax takes longer to dry and thus allows more time to reposition the panels into place. Dope also, especially when "hot" with thinner, allowed the undercoat of Krylon to seep through. If not using an undercoat, this would not be a problem. The dope also gave the most matte finish. I'd meant to try using dope straight, I.e. with no thinner, but ran out of test space. 2) the white undercoat, again Krylon sprayed directly onto the surface of the airframe, gives the best color making it more vivid than the transfers placed over clear doped airframe. I later remembered Freddie suggesting undercoating the transfer but did not think to do this in time. I can report that the lozenge looks much better with white undercoat. I also tried light gray but preferred the white as it made the colors stand put more. 3) wrinkles are kept to a minimum if you attach one side of the lozenge strip, for me it was the trailing edge, with a simple glue stick. This gave enough tack to pull the strip taut and then lay a coat of Minwax or dope under it. Then roll the strip down tight and most wrinkles disappear. I think the dope did a better job of pulling out the wrinkles over the Minwax, but the difference is pretty close. The transfer film, if you will, does not seem to shrink with heat gun or iron. I guess this is good since it does not distort the lozenge pattern. Downside is that some wrinkles were impossible to get rid of. 4) overlap. If you overlap portions of the lozenge you will end up with a much darker almost solid line where the two pieces cover each other. I'm planning to use this effect to simulate rib tape, an idea I saw in another build log. Well, that's what I've learned so far. I'll try to upload pictures later. |
