Seized Ground Control Screw

[clean2g]

One of my Ground Control coilover screw seized on my 2g.. WTF is up with these things? It's like the shittiest design, I've only had them for 2 years and they're falling apart. Anyway, anyone ever deal with a seized screw in these? I drenched the screw and surrounding area with liquid wrench like 3 times.. I put so much that my hands smell like liquid wrench even after a thorough wash. Any suggestions? The hex is starting to strip and it's pissing me off
