never installed the kits before but I had installed a lot of adhesive vinyl,...
heating the moulding
while bending around wheel arches is the only way
that I can think it would work,....
you need an industrial heat gun, not just a hair dryer
you need another person waving the heat gun over the moulding
while you guide it around curves.
you may need some gloves that shield your hands from heat
don't hold heat gun in one place too long
it will ruin the mouldings finish.
I did not know you had to make cuts in corners,
...sounds like something TGW would sell,.....
extra adhesive: 3M Brand 2 sided black foam tape would be my guess.
there may be videos on youtube showing someone install the kits,....
you would think a product that costs as much as
the woodgrain and moulding kits do,....
would come with some help for the customer,....typical TGW.
