what paint to use need a white that wont yellow

ok guys I painted my African queen with rustoleum gloss white it looked great put it on the shelf for a bit and now its a yellowish brown. I don't smoke so that's not it. I need something I can use and I would prefer to not have to strip the rustoleum the hull is a thin ABS plastic so I don't want to have to use stripping agents on it. I am open to all suggestions.

I would recommend wiping down the hull with denatured alcohol. This will remove the oils from finger prints and dull the gloss so the new paint will adhere better. I have used Plastikote white paint and it has not yellowed, however I have not used it on ABS. Try it on a piece of scrape first. Plastikote is my for choice for can spray paint.

I have had no problem with krylon turning yellow but have with testers enamel and other enamels. I add a drop or 2 of blue into white when I use my airbrush. That stops any yellowing, keep in mind that that would be 2 drops to a 1/2 pint of paint.

I have a model car that was built over 25 years ago and painted krylon gloss white. No clear coat. It is still as white as the day I painted it. Others painted with testors and other hobby paints have yellowed.

I agree with Charlie, I 've been into modeling for over 40 years . the drops of blue will do it.

In the sign shop I worked at part time, our painter added a couple of drops of aluminum paint into the white, said the aluminum helped with the reflective quality of the white. Jerryj98501

Adding the trace of blue sounds logical - in the elder days detergent sellers spoke of the "new blue whitener" that made things "whiter than white" only a decade or so after my granny used to sling a "dolly blue" (small sachet of weal blue dye on a stick) into the wash. The aluminium paint also sounds logical, anything to keep the UV away from the lower layers of white paint.
A passing thought - the white van parked down my street shows no sign of yellowing, how about touch- in paint from the local auto accessory shop?

Haze,

I had the same problem on an old styrene hull; my solution was a light sanding and a fresh coat of red. I don’t think I will have to worry about the yellowing again.

It seems that enamel will yellow. acrylic and lacquer will not. When I was in the USCG we would add blue to any white enamal that we used whether for a boat or a building to prevent the yellowing which is why I made that suggestion. It DOES work. Of course as KCAL said, a coat of red will cure it also

Ha ha, it drove me nuts too. I will try the add a touch of blue solution at some point; I thought white paint yellowed due to UV light degradation?

Personally I think the yellow and green combination came out really nicely.
