I have Carl McLaughlin's "How to Model World War II German Armor" book and have been searching for the Power Poxy that is mentioned in the zimmerit chapter. I emailed the manufacturer and they hopped all over my mail. If anyone else is having trouble finding their products, keep track of this thread. I'll keep you updated. They have been really helpful.

They were really helpful. They said I probably wanted the 20 minute Marine epoxy. Has anyone used this to make Zimmerit like Carl McLaughlin did in the Kalmbach book?

Here is the email,

"Thank you for this information, I am going to guess that the 20 minute
epoxy since you say it is white would be our Poxy Marine which comes in a 1
oz syringe 21601 and a 1 lbs package 21616. The other one is probably our
Super Poxy which also comes in a 1 oz syringe 21201 and a 1 lbs package
21216. Some places that carry both products are Menards, Tractor Supply,
Blain's Farm & Fleet and Farm King Supply. You can also try Wal-Mart for
our Super Poxy. If you need anything further please let me know. Thank you
very much and have a great day."

Like I said, nice guy.
