Quick exhaust rust question

[hockeybawler]

So tomorrow my new exhaust tips are finally going to be here and then I am getting the rest of my exhaust taken care of. When the tips come in, I will be going to an exhaust shop to get the tips put on, brola pro xs mufflers put on, and the flex pipe cut out of my speed daddy headers and a new one welded into place. Am I going to need to spray the welds with anything after it is all finished to prevent them from rusting?

Thanks for the help in advance.

You could use engine paint out by the mufflers, might help and look better. Up by the engine, it might just burn off but you could spray what you can reach. Nothing to lose, really.
