Leaky seals on S2 cab

Hi all, whilst trying to fix my broken wing mirrors i had cause to remove the interior door trip on my 89 S2 cab. Whilst doing that, i noticed significant damp on the panel and the metal work. Now i know for certain that my S2 is not completely watertight but dont really want to go through the hellish expensive seal replacements. Is there a quick/cheap/nasty bodge that will help me seal things better. or is there a source of cheap seals?

Im not too concerned about some water ingress into the cabin as such as that quickly dries/evaporates - my concern is the water being trapped between the metal work of the door and the interior door panel as this soaks the fibre board of the door panel and must be weakening it as i suspect it never really dries properly. Would a bead of bathroom silicone sealer (or similiar) around the edge of the door panel help stop water entering behind the panel? I was thinking of using it almost like an adhesive and applying it as a thin bead about a 1/4" in from the edge of the panel and then refitting the door. Or is that just daft as the sealer wont stick to the metal work etc? and i suppose it will give me no end of grief should i ever have to remove the panel again.

Any advice would be most appreciated.
 
Those seals are for coupe version not the cabriolet so arent any good to me (assuming i am looking at the right product). But i agree that bathroom sealant may not be the best way to go either
 
If it's getting inside the door trim then I would suggest it's the outer window scraper that is the culprit, the door seal itself stops water getting inside the cabin. The outer scraper is £23.95 from Forest Fine (though is possibly more for your Cabrio version). It is accepted that some water will get through the seal and there are drains at the bottom of the door to allow moisture to escape, can you check they are not blocked and are actually the cause of the dampness?
 
I have had another closer look at the doors but couldn't see the drains. are they on the underside (above the sills)? or are they tucked in a corner somewhere - i couldn't see any holes on the underside.

also it looks like the water is ingressing near the front of the door roughly where the glass starts to curve upwards - its difficult to explain, but its just before teh verticle rubber seal bit that separates the bit of window that goes down and the bit that stays where it si. There is a track where water seems to have been flowing round that area.

Someone at work has suggested using some talcumn powder and alot of water to try identify the source of the leaks - going to get them to give me hand with that sometime over the next few days. I have also been told that applying some silicone oil might help revive the seals a little so i am also going to try that.

Our Subaru has frameless wondows, so the seals do a lot more work than normal. I've been told that cheap-as-chips glycerin from a chemist - less than a quid a bottle - will keep them supple and stop shrinkage.

Anyone know if this is true? [&:]
 
i think that must be a similar theory to the silicone oil. Cant use normal oil (WD40 etc) cos it will eat the seals but a silicone based one apparently work wonders if applied as preventative measure (once every 6 months. That nugget of advice comes from a mate who learnt about it when he had an MR2. He used it and said that his seals never misbehaved. He still has a load left and is going to loan me some so i may be able to report back on the results in the next few days.
 
Yep, as above silicone based lubricant is good as is PTFE based lubricant.

I use a PTFE based spray lubricant on all of the seals on my MX-5 (and will do on my S2) and it does an excellent job of keeping them supple and repelling water.

It works a treat on sticky electric windows too.
 
Arrrg - I was confusing myself with the drains on the underside of the sill. I've just been looking at my door and can find none either [&:] Sorry for the confusion
