On ANY rocket I have seen the "papering" technique used on fins, they always look like substandard RUBBISH.
If you want to be lazy or un-traditional and still have a nice finish, lightly sand the fins then apply iron-on R/C airplane MonoKote or Ultrakote.

I just stick with good old-fashioned Balsa Fillercoat and then Sanding Sealer for prepping ALL wood parts for topcoating. This "Dope" method works the BEST and has an olde-tyme proper nostalgic AROMA.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
