Yes indeedy!
Neded to do 3 of my 4 75's. Now all 100% dry.
I found that there is only one way to do it properly. If you don't, you may end up by making it worse or inadvertently causing damage. Please PM me and I'll try to explain (or call you).
Bit long winded to post here, and I'd need far too many photo's!
