hey guys, i'm looking to replace the seal on my windshield becuase it hasn't had one in like 4 years, i know i'm gunna have to take out the windshield, but i'm going to need to sand down the edges that the winshield sits on because over the years it has rusted in there pretty good but not to bad, what should i use for that, any certain type of anything that i should use as materials to take care of that besides your out of the ordinary sand paper, and, how hard is it to put a new seal back in, around my area, there is not on place at all that won't charge me less than 250 bucks to do it, i'm hoping to do it myself if it is not to hard, has anyone had any experience by doing it yourself and what type of sealant should i use for it?
