As you can see it used to have some plastic covering. The frame is held together with (sorta brittle) plastic pins but my main focus is how I'd re-cover the frame in plastic:

  • What sort of adhesives should I consider for outdoor metal-plastic bonding?

  • Is adhesive and soft (clear) plastic even a good idea?

  • Have any of you done something similar?

I think 'mil' is related to imperial measurements. No way is 6 mil greenhouse plastic 6mm thick.

There are about 40mil to 1mm, though, and I don't think they're talking about food wrap. But plastic greenhouse panes are about 5mm thick, so maybe that's what is meant here.

shit I dunno, it's thick. I figured it was some nominal b.s. like with lumber where it's totally not the thing, but people talk like it is. I would guess it's like 1.5-2 mm actual. I don't know what "mil" refers to, maybe some machine gauge?

found an answer.

This thickness is indicated as MIL (thousandth of an inch).

I worked for a while in The Academy, so we flipped around units a lot depending on the audience. I just assumed this was one of the SI friendly units.

what a dumb country. thousandths of an inch, what a useful meaurement! lmao

Yeah that's what makes it confusing. Shortening mm to "mil" is pretty standard when dealing in metric. But will be orders of magnitude off if it's in imperial measurements.
