exactly Matt!
take your time!

heating and RE-heating the paint in intervals of the semi-degree rolling step by step is REALLY important!!
I did this 3 times on other cars and it works perfectly.
also be reminded, that you mostly do not need to go all the way round but mostly about an area of 20 to 30 cm, so from the top middle 10 to 15 cm left and right.
this also reduces the danger of spoiling your paint.

and dont forget to clean the inside first.
and when done dripple some wax inside the created seam/fold.

good luck!
