No problem man! I haven't read your build completely but I really like the idea. I'm interested in getting into RallyX so I'm interested in your process and success. Your tube framing and welding looks pro man. Kudos. I might have you come over and do some for me sometime
I've found that pics do attract more attention to your posts for sure. You'll notice in my build threads, there are only a few posts without pics. Also, if you want specific questions answered, you might want to start a separate thread. That seems to work best for me. I have quite a few questions that get missed in my build postings.
Did you have any questions still open? Maybe I can help.
Good luck with the undercoating. What I did on mine was fix problem areas. I was poked around to feel for rust underneath the undercoating, sanded it off, patched the rust spot and applied the new coating.
