Rust Question

Hey guys/gals, i bought my s13 hatch not to long ago, it was a 1 owner lady driven, im sure she stored the car and was not winter driven, as it is now my DD i rinse the car top to bottom to prevent rust, but it seems rust is expanding faster then ever in the rear wheel well and rear quarter, any other ways to slow it down ? or fix ? will post pics soon THANKS

there on grays road in stoney creek i believe. they stock POR15, its thick rust paint that u brush on. it stops rust dead in its tracks, its a bit pricey but you will never regret it.

the bottom of my car is rubber guard coated, its just on the rear quarters where its spreading fast, seeing new bubbles and the inside the rear wheel well

Sand it down, apply rust inhibiter spray, bondo, sand again, the apply cover-up paint.
Attack this issue now, before it eats your rear quarters.

Either that or learn how to weld.
