Good seam sealer

[decca]

Looking for advice on seam sealer, what’s the best and easiest to use, in a tube or the paint on stuff? It’s for a bit of a restoration project on a Morris 1000.

Is the tiger seal stuff any good?

thanks

@decca I think they're much of a muchness

Just got to keep the water out

We use innotec seam sealer at work seen cars restored 5 yrs ago and no seam sealer issues.

I prefer the seamsealer in tubes the paint on stuff is a lot more hit and miss.
Sikaflex 221 is good and cheap, the tigerseal is fine too.
Gun it on and if you want a more oem look. use a paint brush and some thinners to brush it out

I use upol grey stripe brushable seam sealer, never had an issue

Basically any polyurethane sealant in a tube will outperform the brush on rubbish.

Unless you want to get the panels apart in the future then you're better off being an ice-cube in hell.

It is immensely good stuff though.

So Sikafelx it is then.

Thanks all.

Tiger Seal is good but I have never successfully managed to keep it moist in the tube. It has always set by the time I've used it again, despite clingfilm etc. I now use the cheaper sealant from Tool Station or the brush on stuff if it's a small bit. Either way, I'd try to do big chunks of your sealing at once if using the tube stuff so you get your money's worth before you have to chuck a hardened tube.

Exactly this, also applies to Sikkaflex, I usually line a few jobs up and do them all at once.

when I repainted under my cars after striping them back to bare metal, I didnt use any seam sealer, I just bushed on a thick coat of the jotun epoxy primer at the corners, so far no issues. my thinking is that even the hardened paint will still be more flexible than the joints it is on

That's one of the beauties of Sikaflex is that it remains flexible even once gone off.

For my restoration project (a Morris Minor 1000) I am using a mix, most of the welds are getting brushed with Grey Stripe - it has the advantage the Halfords sell it so when I run out over a weekend I can go and get some more! For areas (particularly under the car) where it will not show I find it easier and quicker.

For jointing between panels e.g. when putting the wings back on I will gun a small bead on from a tube.

I am actually finding all of the UPOL products quite good and using spray cans a lot more (e.g. acid etc primer and weld through primer, not for the hi-build or respraying the car) as the quality has gone up and it is much quicker / better than using brush on.

Be careful using sika flex when you are bolting the wings on.
You may find they will get wrecked if you want to take them off again or need to adjust the alignment of the panels.

After they are on a bead won’t be a problem, as you can cut through it easily enough but separating glued panels is another matter.

Etch primed, innotec seam sealer then innotec spray sealer over most of the seams.

3 coats of primer, then 3 coasts of colour if direct gloss.

3 coats of hi build primer?
Is that wet flatted back too?

That is the only down fall with Tiger seal. I also done the clingfilm trick but did not work.

Depends on the customers required finish.

Most end up with stone Chip before the paint goes on

This is the stuff that put me off brushable seam sealer.
There may be good ones out there but this one is junk.
