Someone on the CB250RS Facebook closed group suggested I try ABS slurry to fix cracks and broken mounting lugs on plastic side panels etc.
I thought back to the 90's, when I couldn't buy the correct angle guttering joints for my 1030's house and some old sage where I was working at the time (who had an immaculate BSA Gold Flash Combo) cut a section out of one to reduce the angle and bonded it back together at my required angle with a paste made up out of the waste material dissolved in MEK. They bonded beautifully and are still on my old house when I went past earlier this year.
Has anyone tried this? I guess the panel materials will have changed over the years. I think the 250RS panels are ABS but I seem to remember my 750K0 panels and airbox were made from some form of styrene. But I guess the theory is the same... dissolve a piece of the same material in a suitable solvent and use that to repair the panel.
This what the FB guy said: Quote : "Google abs slurry,,, and make some .... glue it on with it ,then build it up round the crack ( takes a day or two to fully cure) permanent fix ... I glued 2 halves of a panel together with it .... you could bend it as much as the parent material , it doesn't glue, it bonds. I have tried epoxy, fibreglass glues, nothing does it like abs slurry"

Only reason i can think of it not to work is if the plastic was"de natured" by uv light(cant think of another waybto say that)

Ash,
Floplast do an MEK pot with brush to fit their plastic pipe stuff together. Get it B&Q I used some spare I had recently to repair a plastic door hook. Keep the top on tight...it evaporates really quickly.

Good point that Bryan ...on late 60's early 70s panels the plastic goes really brittle.

Hi Ash,
I have repaired quite a few panels over the years with home made gloop. In the early days I used to cut up broken panels into tiny pieces to dissolve in acetone but then I bought ABS welding rods from RS and cut those up instead - much easier!
There's a piece on my site

Nice one Ian! You’ve got me converted from fibre glass!
