Well finally, the temperature rose to 9 or 10 deg C today and being dry for the first time in a while, today was the day to put the body side moldings on.
Washed car, then measured as per the instructions. I ADDED an inch to both measurements because that was the width of the masking tape and I lined up the TOP of the masking tape with the string line. I Re-checked the masking tape line against a new string line and found that the masking tape had sagged down just over an eighth of an inch in the middle. lifted over half the tape and re-positioned. Check again all now OK with the lines on both sides.
I measured out the trim end with smaller pieces of masking tape. Then I cleaned with the cleaning pad and then the pro-bond.
When it came to fitting I removed the protective film on the end pieces of adhesive BEFORE the trim was placed on the door. I did of course peel about 12 inches from the straight end as per the instructions.
I used a heat gun to warm up the doors first, I think to be honest if the temperatures were any lower there could of been a problem getting them to stick.
I could well be the first in the UK to have these fitted! No one was interested in fitting these for me. *too small a job*
but I'm glad I did it myself in the end! Many thanks to all who shared their photos and comment of how to fit.(yippy)
