Citadelgrad Posted June 9, 2021 Share Posted June 9, 2021 I have a many year old bottle of Future that is 95+% full, I have used it for various model work for at least 5+, maybe 10 years. It sits in the garage on my workbench, and I looked at it yesterday and the liquid is very yellow. Photos of the product online look as clear as water. I used it for some lenses on an IP, and it was fine, but I am wondering if the yellow would be visible on a canopy, for example. Should I ditch it?

blackbetty Posted June 10, 2021 Share Posted June 10, 2021 my old bottle is fine. i tried to put some in a gunze glass paintbottle and it gummed up in a few months. seems to depend on quantity Link to comment Share on other sites More sharing options...
Thomas Lund Posted June 10, 2021 Share Posted June 10, 2021 Try it on a spare transparent part... I would suppose that everything that can be applied and then dries up in the air can be corrupted by a not completely sealed container. I know that my Vallejo primer is susebtible to this but then I open them frequently so new air gets in... Link to comment Share on other sites More sharing options...
ivanmoe Posted June 10, 2021 Share Posted June 10, 2021 I don't find the yellowing in floor polish to be a problem, likely because the coat that ends up on models is relatively thin. Don't know what the very long term ramifications are. What I have seen turn noticeably yellow, over a period of years, are vacuform canopies. Nothing much that can be done about that, except, perhaps, replacing the darn thing. Link to comment Share on other sites More sharing options...
Helmsman Posted June 10, 2021 Share Posted June 10, 2021 Mine is about 20 years old and it has been moved few times across different countries, no yellowing and still doing great. Link to comment Share on other sites More sharing options...
KUROK Posted June 10, 2021 Share Posted June 10, 2021 I keep my bottle in the freezer. It has been thawed several times and seems to not be affected by that. No yellowing so far. Link to comment Share on other sites More sharing options...
Bob MDC Posted June 10, 2021 Share Posted June 10, 2021 (edited) UV light is best suspect has a habit of oxidising stuff. Anything like that cool dark is the best but if you want to go OTT https://www.smooth-on.com/products/xtend-it/ We spend a fortune on stuff like this, now we used old fridges for all our stuff including super glues, pick them up in a secondhand shop run till buggered and it works !!
