I am sorry to hear this about your masks not fitting properly. I can imagine how upsetting this must have been, especially when you come home from work all excited, ready to go since your parts have arrived, only to be disappointed later when you discover they don’t fit.
I only used masks once in a while, and I’ll admit they are much easier to use than having to mask off the windows using tape. Hang in there buddy, at least you’re not masking the windows in a G4M Betty !!!
Please keep us posted on how this works out for you.
