Can the product effect a seal between fibre glass reinforced plastic and bitumen painted plywood? Is the cured product compatible with bitumen paint?

Hi, this item has excellent adhesion to polyester and plastics including pvc. Might be a problem on items that bleed oil and its says do not use in conjuction with bitumen or asphat.(use weather mate)

Does it bond lead pvc and brick

You bet but make sure that the brick work is clean before applying and press it well on to the brick work. I used it on a split in some lead work over brick which had caused a leak in heavy rain around 10 years ago and it was still doing it's job last time we had some heavy rain, great product.

Would it 'stick' two pieces of lead together-so I don't need a gas gun etc

I used it with IVO lead substitute flashing and it does stick that together very well.Not tried it with lead.

Is this any good between conservatory and brick wall to fill a gap?

Yes. I am assuming you are filling the gap between the brick and lead flashing? It is a good strong sealer
