Liquid Mask?

Does anyone use liquid mask on there models? I am building the Tamiya WRX sti and it seems perfect for the premolded underside detail, but I've never heard anyone in this forum using it. It's very popular in the R/C car world.
Is there some reason NOT to use it on model cars?
Also, anyone tried Testors acrylic paints or any other acrylics?

Thanks!
Michael

What's liquid mask?:rolleyes: :angel:

I tried it a long time ago, when I had much less experience, but I just made a mess of it. I haven't tried an lately, though; sorry....

Ive never used it myself but those that i know that have, reckon it's great
