Hey guys i'm not to sure if this is where i should be posting this, so if it is I apoligize. So i bought this car a couple of months ago, when i first posted on here i said there was no rust, yeah well i was wrong. I found rust first in the trunk where the spare tire goes because water had filled that up, at that point i didnt know how water got in there. A couple of weeks ago we had a bad storm and i went out to my car after it passed and i had a lake in my car. I pulled all the carpet out let it dry (carpet is still not in) and i tried to figure out where the water came from. I thought it was coming from the tail lights but i did a very ghetto thing and im sure ill be flamed for it but i put gorilla tape over the areas i thought was leaking in the lights i thought that might have fixed the problem. No lol. After i had a lake in my car again i looked more in the trunk and i saw that there was a huge rust spot in the top of the trunk kind of and im guessing this is where the water is coming from or maybe the rear window i'm not sure. Do any of you know how much it would cost to fix the rust that i have you can see in the pics below. Or can i not fix that rust at all and i'm pretty much screwed sooner or later. and also is it possible the rear window could be causing the leaking as well there does seem to be condensation looking stuff in the bottom of the window after it rains or gets wet. Thank you guys for the help and sorry for such a long thread haha.
