What do you have to loose? I used to do the spray on resist and I would cure it prior to exposure in an oven. IMO, it really helped keep the traces sharp.
 

Are you sure it's dedicated solder resist film? The blue dry film photoresists I see at aliexpress are standard etch resist dry films, not intended to be baked or cured. I remember that we used these films as solder resist in our institute PCB lab in lack of real solder resist films, but they aren't actually heat resistant.

Industry standard solder resist films are usually baked plus UV cured, see
 

The first product is an etch dry film photoresist, probably not suited as solder mask. The second is a temperature resistant sticky tape, not photo sensitive as far as I see.
 

any idea where I could find some
the only solder mask I found is paste
