This might have been discussed a million times over in this NG but has
anyone got a verdict on smoothover and potential uses? I have read on
various DIY review sights that stated it was really poor and gave a
rubbish finish.

I have started using it in my house. I found the 'damaged walls'
variety is very good for covering flaky paint and cracks. After I
steamed some wallpaper from a room in my house the paint was flaking
off all over the place. With a bit of perperation I found the result
after, using smoothover, to be really good and after sanding/painting
you would never know the damage was there.

I see they do a variety for going over textured wall paper. I have a
hallway covered in the horrible stuff and was wondering if this would
be suitable to go over this wall paper. Anyone had a go with it?

Any views or opinions?
