I hand putty the zimmermit on my Tiger. It was cheaper than the kits , but took along time to do, about 4 1/2 hours.
If I do another one I think I will get the kit. It cost 4x more than the putty, but it looks way easier and less frustrating.
Glen have you checked with ETO Armour. I believe they carry them too.
