Hi. Fruil tracks are great. But be warned, once you do a set you will be addicted to them and will wnat a set on every model you make. Ha, ha! Also, the set I picked up for the King Tiger I did here a while back were the most complicated ones I've run across from Fruil. Many, many parts. Each two-link 'unit' consisted of 7 parts, which makes something like 200 parts per side! But just take your time and they will come out okay. And they will look fantastic when done and mounted.
I just spary mine with several light or medium light coats of red oxide auto primer and give them some dark washes with oil paints and a dry brushing of sliver or aluminum and they look great. As I get to the end of the run I test fit them to see just how many more links I need to add to get the correct sag effect.
Good luck and take care.
