My wife has a crafting heat gun... will this be hot enough to heat the lead for the powder paint to adhere? I still plan to bake in a small oven afterwards, but the initial heat...didn't know if this would work or if I need to get a regular heat gun?

Here are the details for it - thanks in advance::
