the lower door body panel on my car came was coming off the other day so I decided to take it completely off and re install it .. my question what is the best way for me to install it and what should I use to clean the door before I apply the door body panel ? I already have a goo gone bottle to take off the sticky let over glue. and I have a 15 x 7/8 foot roll of 3m super double sided tape.. any help will be great.. thank you
