Automotive sealant / Sikaflex type stuff

[NiceCupOfTea]

I need to seal a few weather seals around one of my cars - looking for something that is waterproof but doesn't set hard so seals can be removed at a later date.

I think I used Sikaflex before but it set solid in the tube before I could use it again.

Any suggestions?

Tiger Seal? We used to use it to blend the seams of body kits on XR2s and the like, ah to be young!

Will I be able to remove things that have been stuck on with them after they have cured? That's what I'm after. Needs to be waterproof & flexible, but ultimately removable.

a decent quality translucent silicone sealant will be as good as anything

This is what you want. http://www.waysideadhesives.com/Masterseal-Butyl-R...

Most of the RTV silicone sealants will do.

I've used bathroom sealant in the past, it lasted about 5 years before it needed re-applying.

The best stuff would be Dumdum sealant, which unfortunately is like gold dust now.

3M make a good alternative though, which even comes on a roll which makes it easy to feed into the back of a weather seal

Sikaflex do a non-setting sealant too. Check out their website.

Thanks guys, I have ordered some of that butyl tape. Also going to get a multipurpose tube of silicone sealant - looks better than the polyurethane stuff if I ever want to get the seals off again!

By all accounts, not so good when you want to remove it though! This is a metal trim piece that holds the carpet down and has a rubber seal going over the top of it. It tends to leak so I want to seal it, but if/when I remove carpets to get to things it needs to come off!

Butyl is not dumdum; it's an industrial strength blu-tac is about the best I can describe it, like black chewing gum.

Thompson's roof and gutter sealant

Used this on my Fabia's leaky rear doors, it's permanently flexible, picked it up from by local B&Q.

That sounds like what I'm after though - not using it for adhesive properties, but for its sealing against water properties.

The last ebay link was to Dum Dum / Butyl tape so it seems it is the best equivalent available now...

Had a rummage in the garage and found a couple of tubes of sealant: UniBond roof & gutter sealant (waterproof, butyl, flexible) which I think is what I used before, and if it's not solid in the tube is what I'll try again.

Also found some clear Unibond multipurpose silicone sealant.
