I've been looking forward to getting a heat gun to eliminate bubbles in my epoxy products for a long time. For the price I wasn't expecting much but I wanted to try, the photo I'm sharing is an example of how this gun didn't completely remove all the bubbles and I don't even mean the ones below, the ones I give you show, are at the top! These should literally be the easiest bubbles to burst. Disappointed that it only has one setting as I do many different projects and can use different speeds but it might have been mentioned in the description and I didn't read it so it's my fault. I'll use it now but wish I had to use a lighter to make sure most of the bubbles are gone.
