A little restoration project (not moho)

[Figaro]

I`m doing a little restoration project on my daughters Figaro car.
It involves removing a section of vinyl glued to a metal window frame which was showing some corrosion, and replacing the vinyl.
The corrosion wasn`t half as bad as I`d feared, mostly just surface corrosion.
So I scraped and sanded it, treated it with rust killer and red oxide, another sanding then a coat of Hammerite.
My problems started when I applied evostick to glue the new vinyl.
The evostick caused the Hammerite to wrinkle up
I then gave it all a fresh sanding and decided a coat of red oxide should give a suitable base, but this also caused the red oxide / Hammerite to wrinkle up, grrrr
Anyone else had this problem ?
Can anyone suggest what I can now paint it with to stabilise it before I continue with the evostick glue
TIA

Are you using a non solvent based version of Evo Stik? Might be better to change the glue than the base coat.

As above, solvent glue on an oil based paint will do that, you need one of them to be water based...

And an etch primer base coat

I`d have thought the red oxide and Hammerite were solvent based as they require cellulose thinners to clean brushes and judging by the smell I think the evostick is solvent based ?
Ah, after googling it seems evostick is either solvent based or solvent free

The photo shows the red oxide on top of Hammerite, if I sand down and get a water based red oxide will that work ?
What prep would the etch primer need given there are now layers of red oxide and Hammerite ?

You may be fine with the red oxide you’ve got once you remove the hammerit.

In my experience Hammerite is very fussy stuff until it has FULLY cured, and that takes ages.

Halfords do a spray etch primer, if I give everything a real good sanding and use this, is it likely to be ok with the evostick ?
