yes , Maybe some resin rivets or bolt heads. Or you could get some hex rod and salami slice some bolt heads???
how thick is the plastic you used for the skirts? You might also try a ponce wheel. if the plastic is thin enough. Or make some narrow strips out of .010 and then use the ponce wheel. Then glue the strip vertically to replicate the join line.
Whatever you do. I am sure that when you get it done it will look good.
Be Well
