at what point do you use it? before the primer on to bare metal or after it on top?

[liam_italian]

Ive always used it before primer, but that's just me

My theory is if the primer doesnt stick to the metal work then the seam sealer will also come away from the body if it was put on after primer.

But im sure one of the more experienced body work guys will give you a definitive answer.

I prefer to use it after primer as it is over paintable and the steel has the added protection of the primer underneath.

I have used it before primer too with no problems.

Always use sealer after primer, and apply paint directly on top. If you're using a non wet on wet sealer, let it cure fully before painting, or else the paint will micro blister on the areas covering the sealer. If you prime and then paint over sealer, it will crack in areas of stress, such as front panel seams etc.

Brushable seam sealer might be better for putting over the welds! use masking tape to make a tidy job of it.

If you have a proper continuous seam weld, then no sealer should be needed. you could brush some on the underside, but otherwise a grind down is all you need, maybe a skim of filler if you want it prettyfied! Seam sealer is usually used on seams, and any areas where moisture ingress might cause problems.
