it will work ok I use it and have some its expensive but I got my pots for a fiver from autojumble
are the holes too big to fill with epoxy primer ?
I used to get it from someone who worked for the CEGB.Tell me about, cheap it isn't. I'm surprised you managed to get it for that price despite it being a boot sale purchase.
I bet the house smelled lovely!I used to get it from someone who worked for the CEGB.
I went in his house once when his missus was painting the living room, she was filling holes in the wall with Belzona;-)
A friend of mine did something similar to repair the wings on an old Hillman Minx. He worked for an engineering company that had a foundry & they used some sort of 2pack epoxy for making cores or patterns, not really sure what it was used for. We found if you mixed it with polyfilla to make a paste it went as hard as rock, you could hit it with a hammer & it wouldn't damage it. You could not smooth it off once it had gone off though, but you had about 12 hours working time with it.I bet the house smelled lovely!
Where I used to work we had bakerlok - a very expensive two pack thread lock, the yardman had a rusty old Vauxhall, one weekend he decided to repair the wheel arches. You can guess what he used for filler, it was probably worth more than his car!
Belzona is brilliant stuff. It will do the job you describe.
id also go with jb weld if you dont want to fit new metal ....or just epoxy prime it and smear some seam sealer over the holes
Mixed with a bit of fibreglass. Or glue a patch down with araldite or PU adhesive. All bodges but maybe all you're looking for.
