Many days isn't THAT long in the scheme of things, i'd fix it. Their car though, if they think it won't bug them every time they look at the thing, then ignore it. It's not going away though or going to fix itself though.

I think the main issue is that it goes to junk. I've got it twice before and it happened both times.

Probably fine with a gas mix, pure CO2 might be a bit harder. At the opposite end of the scale i've used 0.6mm to weld 12mm reo into a table before. All about the tuning of settings as you say. Spot weld method FTW.

Ah my bad, figured the whole shebang was custom.

@xsspeed is currently shopping pistons I think so may be able to chime in on options

Fair enough then.

WOF fails, as mentioned. People run around with wires sticking out of their tyres, doesn't mean they have found a loophole on tyre requirements. No idea what car you have, but how do you plan to turn it into a light goods vehicle?

OEM is fine from memory and yeah as you say usually just imports and rear windows, the rest will be up to inspector but are fails usually. For stickers it depends where and how far they extend from the edge of the window. Also depends on vehicle class and all sorts of rules. Plenty of info for tint / overlays / stickers in the online VIRM documents. "came with the car" isn't going to trump any rules.

What does unblocking it do? Apologies if you're already done that, seems like it's in limbo and you're not allowed to touch it because it's blocked.

If you like to smash your knuckles as much as I do, weld a nut to a bit of flat bar and wedge it between two bolts heads, then wedge some wood between breaker bar and the front crossmember to try hold it in place while turning*. *not responsible if the heads shear off.

Certs would be a great if you could change every part of the car and it was still ok, lol.

Buying / renting / location? Have had mine filled here before as it's my side of town: https://www.southerngas.co.nz/ They sell / fill cylinders, I assume still do, it's going back a bit.

Post is a bit confusing as i'm not sure what you mean when you say they are already registered. Are they currently registered or nah? Good info here:

I can't compare it against another unit to check how accurate it is, but I got a "KONNWEI KW208" off AliEx. Can test in and out of car (though i've never bothered with in car, it's a process) tells you SoH, SoC etc. Has lined up well with my batteries andd how they have performed. I got it to keep an eye on the fleet to make sure nothing needs a top up. For the money I have zero regerts. Very easy to use, pick battery type, rated capacity and away it goes. Probably same shit different box to the $120 unit you posted. Example only, got mine a couple of years ago and listing is now gone. https://vi.aliexpress.com/item/1005007225230327.html?spm=a2g0o.productlist.main.1.4387x131x131Rb&algo_pvid=04ad75f8-9f38-4415-bf24-ea206a08d9cd&algo_exp_id=04ad75f8-9f38-4415-bf24-ea206a08d9cd-0&pdp_ext_f={"order"%3A"419"%2C"eval"%3A"1"}&pdp_npi=4%40dis!NZD!63.64!28.64!!!263.72!118.67!%402101ec1a17474418129955842e2261!12000039934416591!sea!NZ!116624700!X&curPageLogUid=zOloAPX8pe6o&utparam-url=scene%3Asearch|query_from%3A

Not lately, but in the last few of years. Was CO2 and was ~$90-$100 including refill.
