Woven glassfibre matting and epoxy resin it is then.
I'm only doing it to preserve the original paint on the panels, they'll last as long as they last, and when they finally fall apart, they'll be binned.
I've already got a set of the LPM panels, and very well made they are, although polypropylene is supposed to be a pig to get paint to stick to.
They still sell on ebay

Its this type of GF im referring too for clarification https://www.fslplymouth.co.uk/glass-fibre-fabrics/200g-twill-weave-fibreglass-cloth/#price+per+square+metre:5+Square+Metres it "drapes" really well without much effort, adds very high strength when cured, but easy to work with.
It makes for pretty light structure, especially when single layer. Not too much resin but well rolled out through structure to prevent voids, makes quite a neat job of it.

I use plastic epoxy.... JB Weld is thin and runny, works good as a glue, takes some time to harden. Can file/sand, prime and paint. Permatex is thicker, cures faster, and is very tough. Again can file/sand, prime and paint. I use it to smear a coating on the back side, wider on each side of the crack. and if you're good, can get it reasonably smooth. Then I'll put on an extra coat to build that up a bit.... it won't crack again in that location, lol. I prefer this over fiberglass personally.

I use RS Components 2-Part Industrial Epoxy (same as used in my coil fix)
It too goes really runny when warm and finds its way into tiny cracks.
Takes 24 hours to cure though at room temperature.
