As you all know, most Proton cars has this "disease" of rust appearing on the roof of the car. It is due to the glue that is used to stick the roof to the frame that is too "salty".

as far as i know, one way to treat it is to remove the glue and replace it with glue that will not cause corrosion on the roof.

anyone know what's the suitable glue to use??

can i use those black silicon (use to stick windscreen)??

i spotted a few small spots of rust....beginning stage. so i guess it's...
