Some additional tips. As stated in other posts, you'll use CA glue to attach the pieces to the plastic. I find that generally speaking, medium viscosity (it comes in a green bottle) is best. I usually don't apply the glue to the part. Rather I'll place a drop of glue on the model where I want the part to be located, and then place the part on the model. Or I'll hold the part on the model, and apply a drop of glue where it touches the model allowing the super glue to wick between the part and the model. A drop of Zip-Kicker will instantly harden the glue.
As for tools, I have never had good luck using toothpicks to apply the glue. Either the glue climbs up the toopick, away from the extreme tip or I have to use a really big blob of glue. I make my own applicators out of fine wire (a single strand from a piece of picture hanging wire) gluing a short segment of wire to a toothpick. I find that with the wire, I can get a fairly small drop of glue right on the end of it. I keep a lot of these handy and scrape them off with the back side of an exacto blade after use.
The zip kicker comes in a spray bottle, which is totally useless. I filled a old cleaned paint bottle with it and apply it with a modified glue applicator. Basically, I formed a really small loop in the end of the wire, so after dipping it into my zip kicer bottle, it holds just a drop. I can them touch this the the model right next to the super glue drop that I want to harden.
Do you have some sort of magnifying apparatus? I have one of those lights that has a large magnifying lens surrounded by a circular fluorescent tube. The light and magnification make a really big difference. I think there are magnifying goggles that can give the same effect. If you make something that looks good under a magnifier, it will look great in normal life.
Although, mentioned before, I would re-iterate the need for patience. My first attempts were very frustrating. My wife just kinf got used to the cussing that ensued when I was building the model. I mis-glued many pieces that had to be pulled up, scraped, and re-glued. Don't be afraid of pulling up a piece that is not right and re-trying. Usually you can simply scrape off the old glue. Beware of the "carpet monster". I dropped many a piece onto the carpet where they still reside to this day. When you do get frustrated, relax, take a break, and come back to it later. Handling the photo-etch and the CA glue will get a lot easier with practice. I hardly cuss while applying photo-etch these days, and by the end of your Panther project, you'll be a pro.
Good luck.
