Black SwanCO 04031 Iron Paste Compound Sealant

Works well, used to fill some holes in my wrought iron fence. Very happy with the product. Watch out for the fumes tho.

this garbage doesn't work. I sanded and cleaned the pipe but it still doesn't stick to the pipe very well. After the patch was done, I found that it just soaked up water instead of sealing the cracking. save your money and avoid this garbage. It also crumbles easily after it dries. I will have to waste hours cleaning this garbage up and try patching the pipe again with some epoxy.

Can't find this anywhere.Great product.
