feast watson flat proof polyurethane

[cadeuceus]

Hi all - just a question regarding Flat Proof clear polyurethane from Feast Watson. It dries clear but has a grey/green tinge when being applied. Is this normal or is it "off"? Can Poly go off? If it dries clear - are there any problems with the colour upon application?

Has anyone else had any issue with this product?

Thanks in advance, Gavin
