When I was rebuilding my Love Bug
, I found that McMaster-Carr was a great source for edge trim. Their on-line catalog is great once you figure out how to use it. Trim-Lock is the brand and they have just about every version made. I could not find anything about the belly band on my Love Bug
so I ended up using some of the larger Trim Lock to do the job. It looks great. I also used a difference variety to finish the lower edge of the trailer.
Just measure your thicknesses and the wideth that you want and look at their examples.
