I know this was posted 13 years ago, so asking a question might be a long shot. That being said:
After putting the aluminum flake/asphalt mix on, would one be able to drill through it easily enough? We want to partially deck the top of ours, but I know the paint must come before the decking.
Thanks for reading/replying. Any other advice would be appreciated. We will be buying our bus sometime this month and are ready to drop $5k to start the build!
