fading & yellowing paint?

I've done the "drop of blue" thing and it does seem to work.

I built an X-1 about ten years ago for a friend and put it in the NACA all-white scheme. I see this model on a semi-regular basis and to this day, it hasn't yellowed a bit. It could be that the thing is never exposed to sunlight. But whatever the reason, it hasn't yellowed.

Fade to Black...

yeah its true

I've also heard that adding a tiny drop of 'blue' to the white paint will prevent it from yellowing? Has anyone else heard this???

dont paint the part white. if u absolutely have to, just use flat white and then future it. if it yellows than strip off the paint en repaint it. some types of paints yellow faster than others.

I know this suggestion is a bit extreme and costly, but here goes. If you use an automotive two part polyurethane paint system this will help quite a bit. Dupont Imron and Imron 5000 work very well and will last for many years. I remember FSM had a story about a gentleman that painted a Bell x-1 with automotive paint, It was a very good article.

The down side is that the paint costs around 100.00 dollars a quart. You will also need the activator to catylize the paint...not cheap either. The paint will melt the plastic so you need to use a good quality primer as well.

Like I said, It's a bit extreme. But the results are well worth it.

The issue is UV light aka "blacklight" a natural component of sunlight and the leading cause of skin cancer, find a way to block it and you'r OK. Display cases with a UV screen would help.

I saw the same thing in FSM and I think they said it had something to do with sunlight. Future has a good reputation, but some 'clears' even have a reputation of going yellow over time.

Most if not all white paint jobs will turn yellow over time. There was something in FSM explaining why. I have started spraying any white with Future to see if that will slow down the effect. I haven't been doing it long enough to see if it works.
