Neck Rash

Hi all,
my wetsuit keeps giving my neck a really bad rash. i have a rash vest (Not i high neck one) i'll only be surfing for a couple more months before i go away so i don't want to buy another one.
Is there anything i can do to help stop it? I have been told to use Vaseline.
Any help would be great!
