i have a 90 crx and of course the rear quarters are rusted out...im planning on fixing this but what do yall think the best way to do it....option one is grind out all the rust and then just slap fiberglass/bondo and work from there reshaping the panel(bad idea)...or to cut the quarter out and just replace it?...or what do yall think? need advise asap...any experience fixing this section and how it went

 

your lucky... i just cut both quarters off a crx with absolutely no rust at all... pm me and we can work something out.. they even still have perfect glass in them... 757-236-5016 - nick
