Very nice to see! You build a Porsche, and you'll definitely get my attention!! Great job so far! The way I do gauge decals eliminates the possible danger of using old decals. I use self adhesive clear acitate and stick it over top of the gauges, carefully burnish it down, and cut it out with SHARP scissors (Fiskars). if the gauge bezels are deep, just glue it in with white glue. if the bezels are shallow, dunk it in water -acitate and all, slide the backing off, and glue in place with white glue. this method works great for me. If you wanna see just how good it looks, check out any of my builds, I do them all this way.
