Humbrol white gloss white enamel

[Supertom]

Hey, how's humbrol's gloss white enamel?  I plan to airbrush it.  Does it have a tendency to yellow?

I've got some really old white enamel (25 years) on an aircraft and it doesn't look yellow to me. Problem is, I can't remember if it's Revell or Humbrol.
Otherwise, it doesn't cover too well, you need a primer coat (preferably white) if the plastic isn't white itself. If you don't, you end up spraying so many layers it'll obscure the panel lines.

Great tip I was given many years back....... Add a drop or two (or three) of (generic) blue into the white before spraying and it will never yellow. I've always followed this and NEVER had a problem.

I've only recently read that on the ATF forum too, good tip as the white I put on my Victor and B-47 have both turned yellowish.  I would add that the one or two drops should be applied to a new full tin of white.
