Small rust spot and crack on windshield

[jjmaia]

Hello all,
I have a very small rust spot on my bonnet. What's the best way to take care of it? Its so small so probably buying all the products is not worth and it would be better to go to a bodywork shop?



Also, I have 2 cracks on the windshield (bigger one on the photo). I know I can get it repaired trough my insurance, thing is, this is a Focus witch has an heated screen, would that be a problem and will I need a new one?



Thank you for your help.

A dab of this will stop it spreading. I've had a bottle in the garage for yrs, jolly useful.

Thanks for the tip. Should I just apply it or should I remove the rust first with sandpaper?
