Be sure you clean that paint and or primer off more, inside and out. ANYTHING left on the surface is going to cause you welding issues. Did you use a Zinc "weld thru" primer on the inside? If you did, another BIG tip, spray the primer then leave it until the next to day to weld. It has to be FULLY flashed off and dry or it can cause issues with welding as well.

Now, a real "ecoat" primer or zinc "weld thru" can be welded through with a MIG (Metallic Inert Gas) but most anything else will give any welder issues. I personally have zero experience with the flux core so I don't know how it works with the "weld thru." But without a doubt not letting that weld thru flash off completely can seriously change the whole welding process for sure.
