It has already been declined through: Colony, NICO, Century, Scottsdale, Verus, Mesa, Catlin, and Acceptance.
I recently worked on a similar risk. I provided a standard garage liability quote (excluding products) and then quoted the conversion ops under a separate GL policy. If you want me to work on your risk, please send me the apps you have already completed and I will get out to my underwriters. We do handle accounts in Texas.
