Bobo1953 Posted April 30, 2017 Share Posted April 30, 2017 hi everybody. i have recently dusted off some of my late twenties' builds. they're not bad, i guess, but as by then i didn't use -nor i believe there were such products in my country (italy)- clear finishes, the decals, big and small, have become heavly yellowish, and the film supposed to be transparent, is a yellow-brownish plate around stencils etc. with the industry always in search of new products for modelers, i wonder if someone could come out with something more realistic than the airy-fairy story of sun exposition for decal sheets and /or some specific product for in-place decals in general... thanks for reading and, in case, giving an answer. best greetings, bobo.

midnightprowler Posted April 30, 2017 Share Posted April 30, 2017 I know this, that taking a decal sheet, putting it in a clear plastic bag, and taping it to a window exposing it to sunlight WILL take the yellow away. I have used the technique many times. I don't know what you can use if anything for applied decals. Quote Link to post Share on other sites
Bobo1953 Posted April 30, 2017 Author Share Posted April 30, 2017 hi prowler. i am sorry to contradict your position, but my experience with the sun exposition of yellowed decals is a total failure. and i live in sunny italy...;-) it may be due to the fact that i have double-pane windows... neverthelss, we tried to replicate the phisical conditins of sun exposure in a lab controlled environment and it was just the same. i have also heard that even if and when yellowing vanishes, it will come back in a short time. this is why i am looking for the industry to produce a something that would surely and definitively take away the yellow tint. such a product, if effective, could work also on applied decals... i believe that we should insist asking industry a solution (litterally...:-) ) best cheers. bobo.

midnightprowler Posted April 30, 2017 Share Posted April 30, 2017 Could be the double panes, not sure. I have never had yellowing reoccurring if kept in a bag out of the light once de yellowed. Quote Link to post Share on other sites
