I have tried IPA with no luck. Made contact with Bachman customer service. Very prompt reply. They say IPA will not work as the sides are Tampo printed which is a new one on me. I think it means that the insignia is part of the main colour. I have removed lettering and gone through to bottom layer which seems to bear this out. Have now obtained some Humbrol enamels to try to patch things up. With 10 coaches to do I can see this becoming another project that dies.
thanks. Mike.
