Wife has decided that the hall should be redecorated. Their are lots
of skirting boards, door surrounds and handrail/banister all covered in
gloss white. I am just repainting the woodwork white so what is best,
strip to the wood or just overcoat with Gloss?

If strip to the wood is the consensus what is the best way to go
about this, heat gun, chemical (Nitromors or similar) or sanded
(palm/orbit or hand )?

If heatgun is the way to go is the Earlex HG200 up to the job?
