Roof and gutter sealant is purposely flexible to accommodate heating up and cooling down without cracking. I don't see why it should be a problem in the doors...

The stuff I used for mine and Bezzys car is semi setting.

i.e. Develops a skin but stays soft in the middle

David is quite right in what he says about roofing sealants.

They have this property because they experience extremes of temperature,

moisture and movement. :yes:

Ours don't leak anymore and as I keep saying regular bathroom sealant

really isn't any good unless the joint is 100% dry.

As long as you used plenty and covered the joint right over then I'd

imagine you will be okay. Have you tested with a hose?

You'll find out quickly enough.

I used a product called Sikaflex which is a marine sealant that remains flexible. Has not been a problem for me.

That would be my second choice actually. Sikaflex is good gear.

It does however, harden throughout and adheres brilliantly it's just very flexible when set.

I picked up a demonstrative sample from a builders merchant when it was released which was a 15mm bead

bonding two flat pieces of wood together. It was so well adhered that you could bend the two bits of wood

round until they touched each other. Top drawer stuff!

Sikaflex is a brand with lots of different sealants.

Sika is the brand actually, sikaflex is the product.

Been a builder for years and have handled many different products by them.

What I was trying to say by using the word "brand" is that Sikaflex is a complete range of different sealants so you can't say you used Sikaflex without quoting which one. It's like saying you drive a Skoda rather than saying you drive a Skoda Fabia vRS SE

and others are using it in that context - eg:

We've tried every type of body-shop adhesive and Sikaflex is still the best. It's the most popular brand of polyurethane sealant/adhesive in the world!

Agreed, there are many types of Sikaflex.

Something like Sikaflex 11FC would be ideal but still relies on a dry joint for

full and proper adhesion or like silicone applied to a damp joint will quickly develop leaks.

That's why IMO bituminous sealants are better for this particular job. As they usually

adhere even in wet conditions and if you ever need to remove the ancillaries carrier

they can be scraped off and cleaned with white spirit. Not so with silicone based sealants

which require a specialist removal fluid/gel and if used, would be less than kind to the nearby paintwork.

I had a little look at the link in the first post and it looks very similar to the stuff I used in terms of its properties.

As long as the OP put plenty on and thickly enough I doubt he'll have any water coming in.
