I got one of these kits as well. It's not bad, but like you said it is lacking in quite a few areas. I remember having trouble getting the bumpers to fit right.
I do, however, like that it includes some custom parts that could be used on other cars. I used the wing spoiler from the kit on my 70 Cuda; which I was angry that a wing spoiler was not included with the kit.
It is brush painted. Don't have the money to spray it. I also had some trouble with the paint coming off when I put on the clear coat. I've never had that happen before, but I had to do some touch ups of the paint.
Looks good. I know the fit with this kit was an issue; I did one awhile back myself. I had an issue with the tail lights. They are too small to fit and kept falling into the hole. I had a similar chassis issue with the Chevelle model they make. The chassis sat too far back. I see a bit of the pant issue you were talking about, but your model looks far better than mine did.
Thanks, it was originally going to be Sublime, but I had some extra yellow paint from my Opel and Camaro. I did one of these in red a long time ago. I think it was one of the first few models cars I ever built. It came out OK, but since then I've wanted another that I could do a better job on. I saw the vinyl top like that on another car and thought it would be a cool look for this one.
