    If you didn’t say they were photos, I’d say they were renders. I still kinda think that. Very glossy looking. Well done.

    Beautiful. I now know what I’m going to buy on my next trip to my favourite art supply store!

    Thanks all. The specific material is DuPont 2k automotive polyurethane clear – although there are lots of brands and variations of it available at stores that sell auto paint to the body shop trade (IE FinishMaster and NAPA paint stores). I tend to use ‘spot panel’ with medium speed catalyst, and it levels out fairly well.

    PS – this piece was in response to these beautiful torcs I saw in China:

      And I’m assuming you have to use your own spray gun/airbrush – or are smaller quantities available in their own spray can do you know?


    2. Phil Renato

      Right. I have never found a spray can based clear that is as thick/performs this way. But they do have a similar effect. A big problem is that they have so much extra chemistry in them to keep from curing in the can that if you put enough on to look good, it would start to craze as the lowe layers cure. So maybe 2 coats a day for a week or something?

      Good advice. Thanks for the help.
