Hello again Carl.
It’s been way too long since I’ve checked in here. I have just finished getting caught up with your progress. It’s looking great !
I have used Bare Metal Foil on a lot of my builds. Some of them have been posted here on Imodeler.
I have found that the foil has a lengthwise grain in it. I think it’s part of the manufacturing process. The grain runs lengthwise on the roll.
You can get different visuals by mixing the orientation of the foil as you place it on the model. Try turning the next foil piece 90 degrees in either direction when compared to the foil that you are working next to.
The foil will have a different reflective property that is noticeable when you look at the surface.
As far as sanding goes I would think twice before I did that. It’s much easier to simply scuff the foil on the roll before you apply it to the model. I would highly recommend using a Scotch brite pad in place of very fine sandpaper.
You can also knock down the shine a little bit by simply spraying a clear flattened coat on top of the foil. The more you spray the flat on top of the foil surface the more it will look like it is oxidized.
It will start to look like the aluminum has oxidation in it as you spray more coats on top of the foil. I recommend using something like a Future to seal the decals in as well.
You should also use caution when you are masking on top of the foil. If the tape is too aggressive and it sticks well then there’s a chance it will pull off the foil as you remove the tape.
Sorry I didn’t chime in earlier but I hope this helps you with finishing this up.
You’re knocking it out of the park !
I hope to stay up with your progress in the future.
