You can mix and match them to get different thickness's as well. Most people use the light build on UL to bass or inshore rods and the high build on builds for heavy power fresh water - inshore to off shore rods. Now days I do one thin coat of light to cover the threads and take as much as I can off then on the second coat put a thin coat of high build. It makes it so I only have to do 2 coats normally, and it seems to even out a little better over longer wraps and decals. The high build is a little stiffer then the light build when it comes to how much flex it takes from the rods action.
