Re: White Paint
An age-old problem I think and a friend once told me Crown paint shops told him years ago that the trick is a gloss undercoat (oil based) and then water based gloss on top.
The problem is that oil-based Gloss is tougher the water-based Gloss so by using an oil-based undercoat you are providing the protection but you won't get that high-gloss sheen with water-based paints.
Apparently white gloss painted surfaces go to yellow quicker in low-light conditions too! stevmk2
