You ALWAYS have to fix someone else's damage on a 53 year old survivor.
However, the worst damage was actually done in Sandouville in 1967. They used expanding foam in the sills and they are unsurprisingly most rotten where this space age technology was applied. They even bragged about it in the catalogue.
BTW this is the 'good' side. The worse one isn't apart yet.
I've probably just been lucky with my 6 then. Yeah the foam was a bad idea - they seemed to think they could be lazy and use it to seal holes when they should have been thinking about how the water that's going to get in could be ventilated out.
It certainly did need doing by the look of your pictures, and every 16 saved is a cause for celebration. They are lovely, characterful cars and I travelled in a couple as a teenager in the '80s. They were very exotic to my impressionable mind next to my parents 12TS.
I was tempted to call it quits and get another one.
Then it occurred to me that another one might harbour the same horrors even if looking the part.
Also, I much prefer the Series 1 examples. Even among R16isti having a Series 1 is kind of special.
And they have become hard to find even in France.
Very impressed, such attention to detail with the precise creation of the circular perforations for the central sill diaphragm (castle?) section. My 16TX suffered the same issues when less than ten years old, which in the '80s was considered uneconomic to repair. This experience, combined with a terminally rusted F4 van led me away from Renault for the next three decades years until discovering Ronnie the R4 in France five years ago. Now I'm back and reliving the delights of the '60's and '70's! Keep up your excellent workmanship Baron von Zach, the R16 roof rack is waiting for you in York!
