Aggieman I downloaded your pictures, blew them up and dont see much reason to pull what you have done so far, just a couple of oddly placed pieces of foil is all on the left side of the tail. The steel wool will take care of that for ya though. Oh and the steel wool doesnt really dull the shine in fact it increases the shine a bit. What it really does is if you look at the foil, the shiney side you will see a heavy grain in the foil, the steel wool hides that heavily grained look by removing it. The dull side doesnt have that heavy grain in it. The really cool thing I have found is turning the grain differant ways on differant panels, as on real aircraft the grain of the aluminim runs in differant directions, by turning the grain of the foil in differant directions you can create the same look after burnishing with the steel wool. I found that trick by accident to be honest. I burnish with steel wool in the same direction all the time, with the air flow over the plane just easy to remember for me, thats where you get the look I am talking about on the pieces of foil with the grain in a differant direction. As far as removing what you have done to this point, as I said earlier I dont see any point in doing that as it would be a nightmare I think. I found that with the Micro Scale adhesive that I can remove it with in a few minutes of applying it with out much trouble, but once the glue has cured it has to be scraped or sanded off, then you have the glue residue to deal with. Hope this helps ya out Aggieman.
Have a great Fathers Day
