Alex, thank you so much for showing us this build. I have the Airtrax Aston Martin DBS kit and like yours there is a huge amount of work, so much so I haven't touched it for 6 years.
Watching your build is showing me the light. Please keep sharing your progress, I am really looking forward to seeing the final result.
Can I please ask what you used to fill the holes and what putty would you recommend?
Many thanks
Philip
