hey guys today i finally got around too getting my car on a hoist too get a thorough oil spray, in one corner of my undercarriage there seems too be a huge issue, the other side is honestly perfect.

 

Its all in front of the rear wheel well in like a holding spot covered in salt aha. today i just covered it was wondering if anyones experienced this and knows a good way too fix it?

PS. its the rear lift point area that seems too have pushed up, then right beside the rear side skirt theres a hole, fiberglass it? seems like my opinion or is there a easy way too weld in that area?
