@Paul - Thanks for the comments... Appreciate it.

Got2B will be the last resort for me. I dont want to de/re bond everyday or worrying that it might fell out. The rainy season in Europe in the Fall is very unforgiving and unpredictable and i prefer to do it with Glue at the front and Tape around the perimeter. There is nothing wrong with Glue at the front, i used it before, but it doesn't look natural for me. HD Camera is unforgiving.

I will buy the suggested travel bottles but i don't know whether i can bring those liquids no matter what the requirement is. Alcohol is definitely a must, or else i wont be able to remove the piece or cleaning the scalp without it. And Glue melter to clean the base.

I am sure some people here have traveled before one way or another by Plane. Wondering whether you can bring alcohol or glue melter into the carry-on bag/luggage especially in the United States.
