@Fadi I'm beginning to wonder if this is more of an issue in dry or hot climates where the edge paint dries much faster. I very rarely get the issue myself in the UK.

I'm thinking of performing some drying tests in a humidified chamber vs a dry chamber to see the difference.

I'll probably use the edge of a 3mm sheet of glass to squash the 'it's absorbing' argument.
