hi everyone!
i just bought a 1/48 A-10 thunderbolt 2 and it was opened.it was a good buy only 6$ and it was an offer i couldnt refuse.i made sure that all the parts were there and they were.the only problem is that the decal sheet turned yellow.what causes this? when i put one on the plane this yellow residue came off.it is really grose looking.so any tips? thx -brad
It’s a reaction in the clear film of the decal caused by aging… If you apply a decal that has it over a dark surface, it will probably not show up so much. But if you apply it over lighter colored surfaces it does show up.
The only way I know to get rid of it is to expose the decal sheet to direct sun light. Pick a window in your home that is exposed to sunlight every day and tape the decal sheet to it with the decal side facing the sun. You’ll need to leave it there for several days, checking it every day. The process can take up to a couple of weeks but will work.
And oh yea, make sure the window you pick doesn’t develop condensation on cool/cold days - that will definatly defeat the purpose of the exercise!
khew, alrite, i will count on that tip as well then. I bought a 20 year old tamiya bike model and the decals yellowed out.
Yay! I have the same yelllow problem with my StuG by DML, Now I know how to fix it, BIG THANKS[:D]

I will definately have to give the sunlight trick a try. Thanks for the tip.

I have used the sunlight trick and it definitely works.
You are my hero! I haven’t been able to solve that! Thanks a bunch.
Would exposing the decal sheet to ultraviolet light help? I need some yellowed decals turned white in a week’s time.
grimlock,
It probably would, but I would keep a very close eye on them, especialy if they have any red in them. Ultra violet will not only remove the yellow, but make the reds fade. Usually it takes a while longer to do that though.
Ah I wouldn’t worry about the red. I have some light-resistant opaque paper. See, we have a small-scale printing business and we have a UV-light machine we use for exposing offset plates. I’ll try and experiment with some spare yellowed decals. I’ll keep you guys posted on what happens.
Cheers.

Thx for the suggestion I have a 1/48th HAS A-24 that has been in the stash for some time due to yellow decals Im happy to see that I wont have to replace thm when the time comes to build it.
Quincy… youre a hero… you just saved my 80’s Monogram B-25J decals… thank you thank you
Also, if you’re not sure if the window will have condensation, slap the decals in a ziplock baggie. Another trick if you don’t have any windows exposed to the sun, you can put the decals in a ziplock bag, then place it on the dash or rear deck of your car while it’s parked. This is how I’ve got to do mine. [;)]
