I was thinking of not using it for no particular reason, is it only necessary for keeping water out?
I am hoping I have put enough paint on the under body of the car to not need it.
Might rethink my plan and know supercheap stock Septone stock seam sealer

Ah, no, not quite.
Seams have some slight degree of movement in them, if not from body torque then from the heat and cold cycle, so seam sealer has some degree of flexibility to it...
Paint can and will crack, allowing moisture ingestion and propagation.
Stay away from superdear products here if you want longevity.
visit your local paint and panel shop supplier and speak with them over the counter for all your needs.

Forget the factory like stuff.
Use a good quality polyurethane sealant like Wurth KD bond + seal, Sika 221, or similar.
Can make it look somewhat factory by running a brush over the bead.
Cheers.

I dont really like using them as a seam sealer though.

What about a Mastik?
Mastic is a sealer for removable joints, such as where the front guard bolts to the inner.
Think of a stove top or sink that bolts into a bench top, mastic is used to seal the component to the substrate to prevent moisture ingestion and allow removal at a later date.

I havnt found any real tips, Cunning Stunt of a stuff to use. Havnt used that particular one but have used similar.
Running some masking tape on each side of the seam and thinning a bit at a time on the lid with gp thinners seems to help, bit way easyer to squeeze so.e polyurethane out of a tube and run a brush over it.

From what I've seen they used 2 different types in the factory, one is used in the engine bay and other areas where it was painted over, its a white colour and looks to be similar to the sika stuff. The other is used all inside and is that black stuff that is like a mastic but not sure if it is, it was laid on real thick. I don't think many use the black stuff anymore.

Factory painted over seam sealer is definitely not a polyurethane.
I think its a hardening mastic but not totally sure. As opposed to the non hardening mastic used elsewhere.
