Hello,

Is combined "primer and undercoat" as good as separate primer and
undercoat? Surely one obvious advantage of using separate tins is that
you get two coats?

Is there a big difference between primer and undercoat? I've just put
primer on bare wood and found I had no undercoat so I put a second
coat of primer on and it looks good to me. Have I done something
wrong? Should I have gone to buy undercoat?

Thanks,
Stephen.
