Hey, im still kind of new to the forums and all, but i just recently bought a 90 240 hatch, im getting it ready for a paint job to avoid problems in the future, the paint on there now looks like it came out of a fucking spraycan. but anyways, im doing the bodywork to get it ready and i was taking off the shity tint and i lifted the hatch and there was a rust hole, bout 1/2inch in diameter...its obvious its coming from the hatch brake light, since theres no other place it can get through....so whats the best way to stop it there? any information would be usefull, thanks.

 

cut out the part that is rusting

weld / glue a new one in
