Dear Engr. Robles
Thank you for inviting me as one of the lecturers to discuss on “Protective Coating” in your seminar-workshop on July 12.
I regret to decline this opportunity because of an unavoidable prior commitment. Nevertheless, I attached a summary of my lecture which could be distributed to the participants as supplementary information.
I hope I could be a service to your company some other time.
Sincerely,
Engr. Gerald Rodriguez
Consultant
