I would read the instructions. The instructions say to wait 72 hours before applying the varnish. While the first coat of silver looks great and I didn't have any issues with minimal handling I think that in the long run it would be best to use the varnish as they suggest protecting the finish in the long run. I didn't notice any changes in the finish after the varnish had dried.
I can see why you wanted to build a model of the real car. Beautiful paint finish and like the clean understated look of the body without a spoiler or stripes. The yellow color optional custom interior really stands out and not often seen even with a black car. Great looking engine detailing and the dish slot Ansen style wheels were popular when this car was new.
Beautiful paint color and finish the factory style Z-28 stripes look good with this color combination. The wheels look just like the optional wheels of the day, and they also showed up a few years later on the Monte Carlo SS.
Great tastefully done Kustom and paint work. Like the T&R interior. Clean looking engine and the injector stacks you used look more realistic than the kits parts.
Wife and I got to sit on the back patio this morning after our workout at the Snap Fitness. 8 AM and only 65 degrees. Next week the talking head on TV says that the highs will be in the upper 70's for a change. Sure better than the high 90's with a heat index of over 100 that has been our summer.
Like the under-construction idea as it shows off the intricate chassis work on the suspension. Might want to check the tire tread direction on the driver's rear tire. Can be easy to lose track with directional tread patterns.
