Panel Line tape
I too used 1/64" Chartpak tape on my Hawker Hurricane project. I ordered mine from someplace in California that I found via a Goggel search.
On my Hurricane most of the panel lines were done with 1/64" tape with 1/32' tape used in some places. The access panels where done with aluminum duct tape and semi gloss photo paper for inkjet printers. The 1/64” tape gives a very realistic effect, especially when a weathering wash is applied to the finish. There are pictures of my project on the war bird forum if you are interested. My post is “Ginger Lacey’s Hurricane”.
Best regards with your model
