    Hi everyone. This is my first post and I’m hoping I can get some advice before I take on my first project.
    I’ve got my welder and I’m ready to do some welding, but I’m a bit stuck as to what the best protection to use after I’ve welded and dressed the welds up.

    After welding an inner wheel arch for example - do I apply a Shultz or something straight on ? Do I need to prime it first ? What primer ?

    I’ve came across people using epoxy primer to new welds then paint or shutz over the top (depending if it’s under body or painted panels) any iadvice would be great.

    I just don’t want to weld my new sill on for example and then having rust bleed through by not using correct primer etc.
    Thanks Ian

    I used to use Bilt hambers Electrox applied by brush and then gravotex applied by brush. and the rust stated to show through in places. also zinc primers don't have good adhesion. for the past 4 or 5 years I've just been using Jotun jotamastic 87 on its own without ant topcoat. it seems to be a better long term solution in my case

  5. As always, the answer is epoxy primer. What was the question again? :whistle:

    Agree epoxy is the way to go, I like Jotun 87a but other flavors are available.
    The 87a will work on it's own, but you can apply a stone chip if you prefer the look and a seam sealer is always a good idea to fill gaps. (Epoxy first though)

    Do not use schutz, it's tar based and the work of the devil.
