What can be done to minimise balling up, short of wet sanding?
I have painted a number of parts in Dulux Metalshield 'High Build' Zinc Phosphate Primer. It was a bit of a sod to apply, as it was very thick and tended to skin and the pull if not working very fast. I could mainly keep up with it but in some areas where its a bit of a mess, or run a bit where I got it too thick. Nothing major, but it does now want a bit of a sand and I am getting no where fast with it at the moment.
Doesn't seen to matter what I do, 180grit, down to 40 grit, hand sanding or air-orbital it balls up really badly. Its over a month since it was painted so its not lack of drying time, and while its damp in the air its been in a dry barn all that time.
I really don't want to wet sand it given the weather as I want to get on with the topcoat.
