Thats not the correct stuff.

this is the stuff you need, It comes in a clear bottle, This stuff: https://www.amazon.com/Pledge-Multi-Surface-Finish-27-Ounce-Bottles/dp/B0034792NM

Also, don't use a spray bottle, thats nowhere near an even-enough spray pattern. You need an airbrush to really apply it properly, or manually brush it on, you get different results with each. (You can dip clear parts in it to get super clear canopies/windows)

Whether it's the legs, arms, ab/diaphragm, or head, you should use Pledge future polish. Clear nail polish can damage the paint on a figure, depending on the brand, some don't, but I don't remember which brands. Also it doesn't last as long as pledge, and is just messy overall.

Future polish dries clean on 1-2 coats, holds well, and tightens joints strongly. I had a Masterpiece Grimlock that's legs were straight up loose out of the box, they wouldn't hold a pose at all. One coat of future and they were perfectly tight, and still are, haven't had to redo it in over a year. And it washes off neatly with water.
Only use super glue in any of those joints for a more 'permanent' solution.

But if it's the waist rotation, I recommend a good quality super glue over future here (but you'll have to keep rotating it for a long time to make sure it doesn't get stuck, it might also take 1-2 coats).

Here you go. Pledge keeps rebranding it

Try this method. It works incredibly well. I have just recently used it on some completely cloudy and scratched up transparent pieces and I could hardly believe the result; the pieces became shiny and transparent again with no scratches or cloudiness remaining!: http://thebrickblogger.com/2012/04/make-your-clear-lego-shine/

Please note that the Pledge product mentioned in the article has been re-named. It is now called Pledge FloorCare and the reference to Future Shine has been taken out. But if you read the instructions on the bottle, you will see it is still the same liquid acrylic. I'm linking to the product listed on Amazon so you see how the bottle now looks like, but you can also get it at any Wal-Mart store: http://www.amazon.com/gp/product/B0034792NM/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B0034792NM&linkCode=as2&tag=thebriblo-20
