my main two mistakes were getting excited for the upcoming driving season and not taking a hair dryer to warm up the mirror caps at a minimum and my garage was only at about plus 7C.
also i think my PPF installer might have had a hand in breaking some of the clips before i had my try on it for my sequential turn signal and blue tint paragon mirror install, but i definitely was using the thin trim tool pieces that paragon gave and following the instructions to a T on where to insert and slide up to before pushing with painters tape applied but still broke.....
all fixed now though lol. princess auto plastic fusing kit is a big save for mending tired plastic tabs and clips. holds for now lol
will go to carbon flash caps if they end up flying off but i really don't think they will. at least i hope not... lol
they wiggle very negligible and don't really move so i'm calling that a win for now.
