My LPISM looked a bit viscous to roll on with a disposable roller. The
ProMask kit is a little out of reach at US$650.00 :)
I'm thinking it might be easier to screen print it as recommended. The
main problem I see with screen printing is the clean up.
I'll have to make a screen frame up, probably out of hard wood. The mesh
can be bought off the roll from any screen printing supplier. Its
common for people to make their own frames. I got number 120 mesh.
I think you just stretch the mesh over a frame and then glue it with epoxy.

What will this oven be used for ? I thought you were getting dry film
which doesn't need baking.
