I'm just wondering what types of paint I can use on a PU board before I hot coat it. I bought the water based paint pens but would like to also use spray paint. Just wondering what I can get away with.
My advice is dont do it - that is if you have laminated already and you are planning to paint over that and then apply hotcoat over paint?
Just hotcoat it and then paint the sanded hotcoat with car spray - out of a can is fine.
If you spray paint onto the glass and then hotcoat you will not get the required bond and will find the hotcoat shelling off with even the lightest impact.
