Im doing a custom ramair job on my hood. All of the parts needed for the ram air induction will be glued to the underside of the hood. Now what I need is an adhesive that is really strong but doesnt dry so hard that it cracks and breaks loose with minor movement. I've only got experiece with one adhesive such as this and it was called PL-400, and I dont know if its suitable for what im doing. Maybe a silicon type???? It wont be holding much wieght btw.
