Sealant for my acer?
I would like to restore my acer to a "tree shape" by removing up to five of the lower branches which are turning down towards the ground and spoiling the shape. Do you think I will need to apply sealant (none of the branches are very thick).
I could supply a December photo if it would help ...

No.
I think most people believe that sealants for cut tree branches, do more harm than good. That is certainly what the tree surgeon I use says.

Acers are pretty robust. I've never known anyone use a sealant on cut branches.
There are several where I work which are pruned every year, mainly to stop them outgrowing their spot. They've been there for over twenty years and are very healthy. One was cut back quite a lot a few years ago with no ill effects.

I am surprised you recommend tar wash DHR. I have never seen this advised.

I would agree, no sealant - there's no need.
I gave one of my acers a 'winter wash' last year as it had a bad infestation of scale insects, and it recovered well this year, and no scale insects.
