I bought set of hood blisters and one of them is damaged. The glue that holds the upper half of the blister to the lower half has separated on one corner. Any idea how to fix this or what kind of adhesive to use?

 

Iirc they are SMC. 3M general adhesive would work. You could get away with 3M panel bond or SMC repair if you have it on hand. You will want the piece clamped tight durring the set time. If you think the crack is non-structual you could seam seal and paint.
