Whenever a person uses a heat source for a target, you risk the hot object will bloom. This is why using HVAC foil tape or Tin Foil tends to work well as you get a true representation of size. You don't heat it. The key as I mentioned in an earlier post is to tilt the object back 10 degrees or a little bit so it reflects the image. If it is perfectly straight, it often doesn't work well. There is no heat or cooling required. At night, sometimes you may want to shine your headlights on it to help reflection. Here is a sample at 100 yards at base magnification of my scope during the day. I cut the strips to 1/2 to 1 inch and make a cross. I leave a 1/2 to 1" gap in the middle to give an exact aiming point. This is from a recorded video and focus wasn't great, so it looks much better in real time.
Here's one where I didn't have scissors along so had to leave the strips larger. This is at night at 50 yards with lights reflecting. This was for a different gun.
