Snabbkurs i hur man applicerar en Mylarfilm.

I put some new mylar down in the jet bumper area of my HS2.
I preped the area by spraying it with glass cleaner so I could position the mylar easier and get rid of bubbles.
It went down ok, but looks a bit cloudy now.
Will this go away or do I have to start over?

It will more than likely be fine.
I've found the best solution when applying decals/mylar is this: Take an empty spray bottle and fill it with plain tap water.
Add ONE drop of liquid dish soap, (Dawn, Joy, etc.).
Mix.
That's it!
Depends on what type glass cleaner. If it had ammonia in it, it may have clouded the mylar.
