I heard this from someone. Thought the substance I was told is any clear plastic paint (the kind that's really for plastic models). Better ask scale modelers or Gundam modelers.
I believe it is acrylic so it should be fine. I must state I have never tried it. But on paper it sounds like there should be no problem.
I use it a lot to tighten pin joints, and some ball joints. It makes a thinner layer than superglue, so if the joint is really loose, use superglue over it. If it's just a tiny bit loose, then use future.
Pretty much this. I have been using this stuff for a good while now and would not recommend using superglue over it, but rather coat it little by little. There needs to be a sticky on this topic if one hasn't been made yet, since questions pertaining to this product arises constantly.
Yep. It's simply clear acrylic paint with some additives to it to make it self-leveling and to harden just a bit. Yep, this is my thinking as well. http://www.tfw2005.com/boards/tutorials-how-tos/214559-all-you-wanted-know-about-future-finish.html
I looked for the Pledge product but couldn't find it at Target or Walmart? Do they still make this stuff, did they change the name, and is there an equivalent product? Would this work?
