Ctmodeler Posted February 11, 2020 Posted February 11, 2020 Hey guys Just applied some decals to a nascar model I'm building. When they dried they turned yellow. What can I do to fix this ? Is there anything I can do when theyre already on it ? Also what about the rest of them I haven't applied yet ? Thank you.for help with this disaster Ken
Snake45 Posted February 11, 2020 Posted February 11, 2020 I don't think they've "yellowed," I think what you have is a case of what we call "silvering," where the clear film isn't laying down tight on the paint. A product called Solvaset might fix your problem. It dissolves the decal and lets it snuggle down.
Ctmodeler Posted February 11, 2020 Author Posted February 11, 2020 The decal on the roof did this too
Bainford Posted February 11, 2020 Posted February 11, 2020 The most common cause of silvering is applying decals over a surface that is not smooth or has texture, such as flat paint. It appears there is some texture to the finish on your model, which could be the problem. Is it a base coat/clear coat type of paint? If so, you will need to clear it before applying decals. Another potential cause is leaving decals in the water too long, allowing some of the adhesive to dissolve away.

The decals on this '49 have "silvered", for the reasons Trevor pointed out. It looks different than what happened on your race car. It looks like something has happened to the adhesive that is on your decals. They may be old, faulty/heat damaged or they were soaked too long. My $0.02.
SfanGoch Posted February 11, 2020 Posted February 11, 2020 Brush diluted (consistency of skim milk) Elmer's Glue over the area where the decal is to be applied. Apply the decal and carefully blot it down onto the surface. When dry, remove the dried glue residue from the decal and surrounding areas with a damp cloth and dish washing liquid.

One of my friends in Model Airplane World does this with Future instead of Elmer's and swears by it. I've seen his results and they're excellent. Last couple years I've had good results just starting with a smooth finish, and then pre-wetting the area to be decaled with Testor Decal Set. Sucks 'em right down. Once in a great while I have to do a little touchup with Solvaset.
SfanGoch Posted February 11, 2020 Posted February 11, 2020 Yup, Future does the job. I also use it myself. I suggested the white glue because it's easier to find than Future. S.C. Johnson needs to work on its distribution, which blows.
espo Posted February 12, 2020 Posted February 12, 2020 Another possibility would have to do with the age of the decals. Irregular or flat painted surfaces are always problem, but if the decals are old, say 4 to 5 years old, the adhesive on the decal can cause problems much like you have here. I did a model that was even older than that and the decals started to turn almost like there was dirt between the decal and the models body. I wiped away the adhesive with a Q-Tip before applying them to the model. This seemed to work in that case. There was still enough adhesive to hold the decals in place when they dried and I covered them with clear anyway so they look just as good now as when I did this a couple of years ago. Just a possibility.
Ctmodeler Posted February 12, 2020 Author Posted February 12, 2020 The kit date was 1998 so they are 22 years old
Ctmodeler Posted February 12, 2020 Author Posted February 12, 2020 Anyway to fix the ones that are on the car already ?

Ctmodeler Posted February 12, 2020 Author Posted February 12, 2020 Oh yeah that's right. Sorry half awake man. I'll give it a shot . It's my first build in probably 15 years just wanna get it done lol
Ctmodeler Posted February 12, 2020 Author Posted February 12, 2020 Pretty sure that silvering isn't the problem though. The decals are 22 years old and I believe there in lies the problem after looking at it , but not sure. Frustrating when you get to this point and something gets ruined like this
peteski Posted February 12, 2020 Posted February 12, 2020 Kenneth, looking at the photo I'm wondering if you recall if the clear film areas were already milky as you were sliding the decal onto the car body from the backing paper? Or were those areas clear transparent, then turned milky white as it was drying? What brand were those decals? I don't think this is silvering because the paint on your model looks fairly glossy (which should prevent silvering. Silvering looks more like what's on the photo of the decal on the hood of Jantrix's model.
Ctmodeler Posted February 12, 2020 Author Posted February 12, 2020 Decals are revell monogram out of the box.the decal sheet looks fine and when they went on no indication this was gonna happen. They looked just fine but when they dried they looked like the picture
peteski Posted February 12, 2020 Posted February 12, 2020 Can you take a pair of very sharp tweezers, or a single edge razor blade and see if you can lift the clear film (maybe right over top of Fred's head)? Will the film lift easily, or is it stuck to the paint?

peteski Posted February 12, 2020 Posted February 12, 2020 That is really weird! Never seen anything like it in my 40 years of modeling. Do you have any of the decal setting solutions (like Walthers Solvaset or any other brands)? If you do, see if you can apply some at the edge of the decal and see if it will wick under the decal film.
935k3 Posted February 12, 2020 Posted February 12, 2020 I had this problem with old monogram decals. It was actually the glue turned milky. I washed it of the back of the decals .I applied them and they still stuck well. Monogram had some very crappy decals back then.

Maybe so, but what's puzzling me is that Kenneth stated that when he slid the decal off the backing paper, the transparent areas of the decal film were clear, tuning milky when they dried. If it was crappy glue, would it be clear when wet, then dry milky?
Ctmodeler Posted February 12, 2020 Author Posted February 12, 2020 I'm gonna do more tomorrow. I'll try to wash some of the glue off the decals before applying and see how it goes. Pics tomorrow !
