What's he using for a vacuum? I know if I tried that with my shop vac, I'd have NO ballast left on the track.
Yeah, that is a good question that I would like an answer to. What's he using for a vacuum?
The vacuuming results were impressive. However, the wet water spray was not even and caused some problems with the ballast. He probably should have used a better quality spray bottle, used less spray, and used rubbing alcohol instead of wet water. Also, the glue mix spray was very rough in its application, leaving pits and runs in the ballast. Rather tha n spray the glue mix on, I believe that there are better methods for applying the glue that don't wreck the groomed look of the ballast.
