am painting my 89ta and have the stress crack so often seen on f bodys. they are small by the top rear off the window in the car how do i fix and prevent this from comming back

 

i had a friend weld them up for me. then i ground them down to match the roof. No more stress cracks. but to keep them from coming back again you need to add subframe connectors to the car.

 

i have them and a cage

 

then i'm guessing they were there before the sfc's and cage was installed? you've got plenty enough to keep them from coming back. my buddies iroc we didn't think had them, but when we sanded it down they were there, just hadn't broke through the paint yet.

 

what should i use to weld them. what type of welder, do i need to remove the interrior to do it without a fire starting?

 

we used a tig welder on a freinds car and we removed any intierior that was near it just incase... sparks fall down too so put somthing over the seats if the doors open. and do one small tack at a time so you dont warp anything

 

MIG i ment to type in mig and knoticed it more then 5 mins after i wrote the message and couldnt edit it.... thats pretty stupid that you cant edit it after 5 mins if you ask me!

 

yah we used a gasless mig on his car. it's all we had access to. But you can't tell the difference.

 

Dangit, I wish the guy I bought my car from had done this before he painted it I was redoing my seals this weekend so all I could do for the time being was add a dab of black silicone to cover the cracks. How far will they spread?

 

on my daily driver i've got them but they're only 1/4 inch maybe? and they've been there since i bought the car and it's been 4 years now.

 

Mine are about 1/4" also but it bugs me that a person knew they were there and just painted over the cracks trying to hide it. I also asked the dude of any rust problems and he said NONE, I replaced my interior this weekend and sure as chit there was rust on the floor boards I did what I could to repair them without having to tear, weld, replace etc so I hope my repairs last awhile (until my next paint job)

 

i really dont think the crack will go more then a 1/4 of an inch now that you have sfc even if you didnt have them i dont think it would get to much bigger id say to leave it untill your gunna paint the whole car
