Leaking sides to rear tub sealing advice
My new Td5 hardtop had a multitude of water leaks which bar 1 I have solved. I keep getting puddles appear in the rear. It is leaking through the foam seal. Everything is bolted down tight but there is a noticeable bend inside, as in its tighter either end. The obvious thing to do would be replacing the seal. However I'm a little worried that will not cure the problem due to the deflection. Is it worth using a mastic to seal externally , and if so any recommendations ??

Ta in advance Thumbs Up

Having said that I put new seals in mine when I rebuilt after the respray. They're really thick (40mm or so) 2002 90 Td5 Station Wagon

It has the correct bolts and brackets George. Additional ones would have to be drilled, not the easiest and permanent holes Big Cry I'm sure I've read somewhere on here , someone used sikaflex? I know k9(mal) was an advocate of it. The only problem is splitting at a later date! It's just one corner and under the rear quarter light.

I would unbolt it, replace the seal, and then check for rust/other issues. the standard seal is good except for the one spot by the seam of the cappings. you can add a bit of sealant, but something is cleary wrong fundementally if it's leaking.

It's an hour's work and parts are cheap. V8 90...WIP

Masking tape, upper and lower part of gap, apply silicone liberally in one big line with BARREL gun (skeleton guns are a waste of money and effort) lick finger and smooth it in in one big line. Peel masking tape off.

Sikaflex mastic is a great product we use it a lot at work, it’s easy to finish (like bathroom sealant) but does stick like Censored to a blanket Laughing very waterproof, very flexible, very good product Thumbs Up 2015 HT XS 90

Jim, I had a leak under the rear quarter light (near side) and I thought it was the tub seal, put some dum dum around the inside of the light, no more leaks, worth a try Very Happy Cogito ergo sum

Greeni has made a very neat job, But I would put new a seal in as mastic is quite severe

Thanks Greeni.

Trade tip - Better than licking your finger, use a spray mister, with some water and a few drops of washing up liquid Thumbs Up

I do the same as greeni but use a polymer sealant instead of silicone. I also do the front bulkhead.

Plenty of different brands of proper car body sealer available for the job.

Silicone is a nightmare if you ever have to have any paintwork done.

Quick update,

Rear tub sorted, new seal sorted that. Now found another leak Big Cry

Drivers side roof to windscreen , leaking in the corner where the dum dum has deteriorated and disappeared, dug it out and cleaned up and resealed with sika ......... fingers crossed
