Well I finally got around to actually starting it. Ran into heaps of problems, involving high humidity and bad water traps.....

But that's more or less out of the way. One problem I'm having now is panel lining. There's no way the oil-based pen (which is what you're supposed to use on acrylic paint finish) will stay in the lines, and it keeps slipping out. Then it dries almost immediately ~1 second or so. How am I meant to go about this? Based on logic, acrylic being water based should resist oil-based ink, forcing it to go into the cracks, and making any outside easy to remove. That wasn't the case.

I've tried the rubber idea some people came up with. It doesn't work well. I think it might work for other paint/panel inks, but not the combo I'm using.

Can anybody help? One idea I was thinking of was getting some sort of oil to erase the bits outside the panel lines with, since you can use alcohol for the alcohol based panel markers. Thing is, alcohol evaporates off. I can't say the same for oil....
