How to dress a weld on a car boot floor pan

[duffman]

I've had to cut out a section of my new floor pan and fabricate a whole new piece that will allow the existing bracing in the rear seat and fuel tank to all fit. I've welded it all in to place and now looking to know what's the best way to dress the top weld? Bottom weld will never be seen as fuel tank sits right under it. The topside will be covered by the rear seat, but just looking to make it look nice. Would a thin coat of isopon or has anyone any other suggestions that would work well for this? See pics

spray it black put boot carpet in there and forget about it

Given its going to be covered, I'd paint it and call it a day

As above, paint, carpet, forget.

“Dolphin glaze “. Keep it intel fridge until your ready, grope the bag like your making a pizza, watch upol YouTube vids fine body filler

“Zinc 182”. Or “cold galv” from toolstation

If you’re looking at zinc182. If you want aresosol take your bank manager with you. Tin more efficient

You can flatten it out with a grinder using a stone and a fibre disc, possibly also a carbide burr on a die grinder.
It will be a lot of work but if you can reduce the profile a bit then you could go over it with some filler to smooth it out and then a couple of thick heavy coats of something like an epoxy primer and it will become a lot less noticeable.

Using short hot tacks is the best way to keep the profile of the weld down and avoid too much distortion when doing bodywork, when you get it dialled in it almost sits flush.

The weld was done on the back side with a small gap in between the panels. Few bits I needed to grind down on the back side but nothing much. I'll probably just do as everyone else has said and spray a bit of paint over it as it will never be noticed

Powerfile to take the welds down a bit if needed, then prime, seam seal the weld, prime again, then top coat.

Lidl have their straight to metal aerosols on sale at the moment, £4 I think. I did a similar repair in my boot and used the black one over a zinc aerosol primer.

If you’re taking about Lidl paint. I brought a tin of their own brand metal paint, but crinkled but amazing.

Only rust bits are where I twitted it with gardening fork by accident
