Picked up some K2R today before work. Got it soaking overnight tonight and will scrub off the powder and reapply if necessary in the morning. Upon further inspection I'm debating leaving the LH fuse side alone and bend it back to the firewall and fill any partial cracks with thin CA. Would this be sufficient to keep the strength in the fuse or should I remove the damaged part and replace it and the doubler on the inside of it?
