I picked up a little pack of a product called Sugru the other day. I cannot put the packet to hand but according to the website:
sugru is designed to stick to as many other materials as possible. It forms a strong bond to aluminium, steel, ceramics, glass, wood and other materials including some plastics like perspex and ABS and rubbers like silicone and butyl rubber.
It works like modelling clay, and cures like, well, things that cure.
So when activated, it is adhesive, seems to reject finger grease, and is malleable, to what extent, I do not know.
When finished, it is apparently watertight and strong, and very heat- and elements- resistant. Think the rubber seal between a trainers or walking boots' fabric toe, and rubber toe surround.
I have kept the perished pieces that were ready to fall off my seals - I just pulled them off. I hope to use a mixture of Sugru and Sikaflex to stick them back together, rebuild them and fill gaps.
My plan was to use either Sikaflex or this Sugru stuff to rebuild the seals where necessary and then find some kind of latex paint, abrade the seals a little and paint them over with black latex to finish them.
My window leak is 50% of the way up the drivers' A-pillar. This ignores all the other leaks of course, they have other causes and I am on them.
So the seal needs built up at the area where it does not seal properly. I either plan to use Sugru to build up the area in a thin layer by rolling a small piece out with a rolling pin, applying it and then shaving the excess with a razor blade, or to rub sikaflex on with a latex-gloved finger over a period of days to build it up bit by bit, using the latex paint (if such a thing exists) to finish the area cosmetically.]
The difficulty with me is not the repair, I am sure that can be done in a functional way, its the overcoat to give the whole thing aesthetic consistency. Latex paint is not something I've found, acrylic latex paint exists but its bonding capabilities are what concerns me. I think a tack coat of PVA followed by an acrylic latex will be the way to go but this is early days and assumptions just now.
Of course when I get round to it results will be on my rebuild thread.
