repairing mk2 golf rear light cluster

Just bought a set of blue rear clusters which were cheap (ish) because the black plastic surround is damaged.

I was hoping to swap the lenses over to a good plastic surround from another set but after a bit of gentle prying / looking I'm not convinced it's possible or sensible. Has anyone done similar or know how the coloured lens parts are attached to the black part?

Now considering patching with bits from another cluster - there's some videos around of people using soldering irons to melt / 'weld' plastic parts together then smoothing over with filler. I'm sure the smell and acrid smoke is very healthy.

Any tips or guidance welcomed

 

yes i would try and plastic weld or glue in a bit from a scrap light ...smooth it down and texture spray the area

 

agreed, going to practice on some other parts to start with

any idea what plastic the black part is?

 

You will get a good result with superglue (activator will be helpful here). Then you can simply use filler and paint.
