Live and learn. Most of my car lessons came the hard way. After attempting to do repairs on my vehicles unsuccessfully, I have a respect for mechanics. Regarding your bad tint day, I wanted some tint on some windows of my Saturn to keep my passengers cool. It was not worth it to me to pay a pro since my car is old. So, with my $10 roll of tint and watching multiple videos online I attempted tinting. I made one big miscalculation. The lady of the house decided to clean out the basement. So, I had a very energetic lady asking me questions, distracting me, etc. First window the tint was too short. Redid it OK. Second window I did not spray enough solution on adhesive side, so I have a few fingers/imperfections. I learned some lessons. Never tint when in the presence of a lady with a long honey do list. B. I am not a tint pro (but results were good enough for my needs). It is good to keep things in proper perspective. It makes life a lot easier.
