Thanks for that. Have never tried flock, but I have used PVA on mounting board, though with the unfortunate result of the PVA bending the board up at both ends like a banana when used on larger bases. I’ve moved on to MDF now.
Perhaps it’s the brand, but I moved to mounting board because it didn’t bend (much) when soaked in PVA. I also find that the magnetic vinyl under the base eliminates the slight bending of larger bases, when you leave them to dry on a tin-lid. I’ve used mounting board for over 25 years now without a problem.
