Canadair CL70 CFR 58-91588

[Robin Craig]

I have plotted and schemed on most of this project and either found solutions or found money to pay for solutions. However I am stumped with the data plate removed from the rear car.

It is a typical plate with likely silk screened areas and stamped in data in the appropriate places. Regrettably it has some rather clumsy and thick paint that has been splodged on top.

I have tried pushing it off with my finger nail, some success but not much. I put the plate in the freezer to make the paint more brittle but it didn't do much. I am reluctant to take any kind of tool to it, even though the slodges are thick and should just spall and fly if enough sideways pressure is applied.

Does anyone have any earthly clue as to how to clean it without damage? It is the part that is most impossible to replace.
