Are you guys going to do this in the future again at all? I may get another set and see if you can do just 1 coat instead of 2 sometime in the future. They look great, but I'd really like to see what 1 coat would look like and if I like those better, than I'll just sell the other set.
VHT is not very good. Put it on clear lights and it turns purplish. Also have you ever seen someone that has done VHT. Most of the time it looks dull and not very good. I have used VHT in the past and it turned out decent at best. If you saw them side by side I think you would agree its worth it. And as for the hobby shop stuff. That's what someone used on the taillights I bought and it looks worse then horrible.
I used it on my rx7 and it came out great. I had the car for 5 year and it never faded at all. But good prep work is the key.
2 coats is what I got too. I think at some point in time I'm going to get some different ones done lighter. Either just 1 coat, or 2 very light coats. The light still shines through very well, but I just don't want to hastle with the popo's.
