Thanks to everyone for the great advice.I'll pick up a few cheapy kits for more practice and try all the suggestions. I'm building for the the sheer joy(?) of it but still take pride in doing the best I can. Hope to post results of my efforts and your good advice here in the next few months. Sonny

I'm a newbie and having a rough time with panel lines.They disappear after I seal seams etc. and sand. So....... Do I scribe before doing anything in the way of assembly,or is there some magic that I'm missing? Building a Tamiya 1/48 A-10. Using a Pasche single action airbrush. thanks in advance for any help and comments/critiques. Sonny
