If all goes according to plan I will order the PG Astray on Thursday or Friday.
One question about panel lining. Can I use an ultra-fine Sharpie or should I just order one of those Gundam detailing pens?
Also Thanks for the help and advice.
You CAN use a fine-tip Sharpie. The question is do you WANT to?
A fine-tip Sharpie costs $3. It may run for a good amount of kits, and it's fairly easy to apply. But it takes work to clean up, and it leaves a purple shiny effect in the panel-lines. In my experience, the effect isn't worth the time spent. And, on a PG, you kinda want everything to be Perfect.
You could get Gundam Markers. They would look okay, and they're easy to use. They're about $3 a pen, I think, and, well, you're shipping home a $200 model. It's an insignificant addition to price. Problem is they don't last long, in my experience, you can only get them from Asia, and the tip goes bad long before it runs out of ink. Plus, the really thin lines don't take easily. Still, I do suggest metallic Gundam Markers. They are fantastic.
Personally, I use Smoke Grey Tamiya Acrylic, thinned out with 91% Isopropyl. I just brush the thinned mixture onto the part, over the lines, let it dry for about 5, 10 minutes, then take some alcohol on a q-tip (not much, mind you) and rub the excess off. It takes off the excess on the surface of the part, and leaves the recessed detail. This requires a lot of doing, but I love the effect, and I can get it at the local hobby shop. It's $3 a bottle of paint, which will last a good, long while. You also need a brush and rubbing alcohol, though, so it gets a bit more expensive, but then, you wanna have a brush, anyway, for touchups and detail paint, and, rubbing alcohol lasts longer than the paint, is dirt-cheap, and is a good first-aid supply. It's 500 Q-tips for $2, and I use Taco Bell napkins for some of the work. Maybe also invest in toothpicks. ($1 for 1000 toothpicks)
