I just got off the phone with a sales rep from HiTech and he was the most helpful guy.

He told me that all i need to do is buy some clear sealer and some storm grey tint.
Add the tint to the sealer in a separate container and use a paint brush and dab it into the affected area and keep adding a few drops of tint to it until the colour matches.
Afterwards, use the clear sealer and then let dry.
I'll keep you all posted and i'll try to get pics and post it up for before and after shots.
Woo hoo i think i might just get back into the good books with the mrs now.
