How much coating on Polaroid 52?

[Garagorn]

Just getting started using Polaroid 4x5 sheets (#52); how much of the coating goop should I be applying to the prints? I've been doing two lengthwise swipes, overlapping, which seems to put on a good coat. Is that enough?

That's probably good. Too many and it starts to look gloppy and picks up dust.
