Hi,Upsjuan:
Hey ! Building Cardstock models isn't that hard. all you need is lots of patience and a good glue like Aleen's Craft glue. It's more forgiving and doesn't leave the water-spots Elmer"s does. Remember in cardstock you have lots of Bends, Folds and Curling to do.
Also a good pair of very pointy and sharp scissors and plenty of sharp X-Acto blades and a steel ruler, won't hurt!
As far as P.E. I found that the Cardstock building, Helped me, learn how to do P.E. Better. Now after all that I can do heat shields on Model car engines with no problems.
Then I took it to ships. The last time I ever used P.E. on a model car was on a 1/12 Model "T" I did the grill surround out of the brass left over from the brass trees from a Tank Model. Yes, I have used it, Love it, But have to watch my Budget.
I have just been stubborn about spending a lot on Aftermarket in 1/25' I did Buy from the Company( Lindberg's Supplier) a full dozen sets of the Wire wheels from the 53 Ford kit. So see, I do it but rarely.
What disapoints me most is that a lot of the Aftermarket( Both resin and P.E.) haven't made Generic ( For standard Autos) Wire Wheels. Have you ever seen a set? Except for Ferraris they are not common. I finally read an article in Scale Auto and had Gene help me, and Now using the plastic rims I create my own wires. More on that later. Happy Modeling.
