After welding I've been putting hammerite kurust over the weld seams to minimise rust and I was wondering if I can put tiger seal or brushable sealant straight over the top of the kurust?

And regarding body filler, do I have to have a layer of primer over the kurust, then the filler on top? Or can filler be applied straight over the top of the kurust?

Thanks

In a word no. You need a primer so use Epoxy. Also as much as i used to use Kurust, Bilt Hamber Deox is by far a more superior product.

So basically whenever using kurust/ bilt hamber deox always spray with epoxy primer afterwards? Then put sealer or filler over the top?

After welding, I prime, then seam seal, then prime again. I use Bilt Hamber Electrox primer, expensive but good. I use a cartridge seam sealer and initially used Tiger Seal. It's a good product but went hard in the tube after one session. After recommendations on the Mig forum, I started using this one from Toolstation:

It will still go hard in the tube, but it's only £4.

I have tried the various recommended solutions - wrap in cling film, keep warm, stand in hot water before use etc.- and sometimes it works, and sometimes it doesn't. Try to time it so you have a lot of seam sealing to do in one go, rather than just a bit, then at least you will use most of the tube in one go.

Yes in a word. Bare in mind to follow the instructions to the letter when using the Bilt Hamber Deox gel and make sure its bone dry afterwards.

Okay thanks for the help. I'll order some Bilt Hanber Deox and get my self some Epoxy primer.
