You mean the entire fly? There are spray-on silicon waterproofing preparations but not sure of the cost. One of those (Grangers is usually considered to be one of the best) or the silicon/turps thing.

I have sprayed the outside of the fly with a DWR spray but the underside seams are all flaky. We are scrapping them off and not sure if this material is suitable for a silicone seam seal or if I have to use a nylon specific one??? Thanks for your advice

If it's just the seams, Seam Grip (the SilNy type) will work or the silicone/turps thing.

The flaking bits is a good indication that it was taped over a PU coated fabric. In this case do keep scraping off what you can and the apply Seam Grip but not the sil type. The sil type could work but the PU version (standard Seam Grip) works better.
