Where are you filling with DumDum  All the joints where the posts meet the sills are welded/leaded. DumDum used around the screens, rain channels trims etc where you want a water seal. |

Quite correct John. DumDum is the useal stuff for windwo rubbers etc and sealing removeable plates but nowadays black silicon is actually better as it does not run under heat. Not advisable to use this for windows though

DumDum doesn't run when hot so I don't know what Gumph you have  and why it is where it is  There should be a load under the rain channel  |

That's very strange Phil I have just done the two coupe screens etc etc in this heat in full sun and mine didn't run it gets sticky but that's about it I used 5 small tins and there is a difference sometimes between tins  |

Well mines a large tin so it will last a long time! I think silicon is better on bodywork as the DumDum does harden and fall off or look as if its sealing and its not!

I haven't used silicone Phil allways reluctant, I know what it does to paintwork when you are doing a respray and if you use anti silicone drops all you are adding is silicone and you NEVER get rid of it |

I presume DumDum is just a brand name for what we call black mastic; a windscreen sealant that came in a tube. It doesn't go hard for years.

Quite correct - and I have not found a like substitute either. Its not as fluid as windscreen mastic although looks very much like it - not as sticky either
