Just wazzing it with an angle grinder and wire brush attachment
Someone liked filler somewhat!
For user survival necessity I had to get the hot air gun out and put the angle grinder and wire brush away - the filler started to smoke and went everywhere - nasty plastic dust...
Need to do the top too.
Paint stripper next stage I guess before a final polish off with the sand blaster

On other parts of the car the holes on the RHS lower A post section turned out to be a lot smaller than I was expecting.
I will be welding these holes - I want metal especially on an important part of the car. No filler for hole filling here!
Thing is - this hole's pretty close to the pretty paint (that's not normally under the front wing) - I suspect I'll be stripping more paint than has been done so far because the plastic filler that the whole cars seems to have been dipped in will melt and de-laminate after welding heat...
