I don't think nitromors will get that stuff off, might help in you growing a third ball though, it's lethal crap
Get yourself a couple of knot wheels if you have an angle grinder. I done the full underside and inner wings of my scirocco in a weekend with them badboys. Was going at it all hours saturday and sunday though, oh and about 90% through the grinder packed in and had to go buy another!
There’s a company on Facebook who do them for like £700 or something. I don’t like them personally, so I’d stay with normal clocks. you’re getting there! I’ve got to do a small repair on my arch this weekend
I love this sort of project and your doing a good job, great if you have the room. I welded over 20 places on my MK3 and the most enjoyable part for me was making the small panels etc that weren’t available to buy, quite enjoyed the experience.
