Looking for suggestions for product and/or technique to strip paint off of a copper canopy (folded seams) over a  12′ bow window. Last painted about 6-7 years ago and is now badly faded, checked, cracked etc.

I tried a waterbased product called “ZipStrip” with little success. Seems slow and spotty and requires substantial amount of elbow grease with a small wire brush.

I thought of heat but am afraid of buckling the copper, (or burning the house down).

My next shot is a solvent base stripper, or any suggestions that may surface in the forum.

Thanks
