New TTI's rusting?????

theres not much you can do about it.. a couple boards have had the same topic hreads latley.. the tti's are the best because of the fit.. all those headder coatings will rust sooner or later.... the directions clearly state that if the car is gonna sit for an extended period of time then you should spray them with wd40 of something similar... my chrome ti's were fine all last summer till the car sat for 3 months with no trans in it and now they are rusting... its my fault in the long run because i didn't spray them down.. i never thought the car would be sitting that long...
