The High Hover tip answered my basic misgiving. Thanks

Thank you for this! My husband says he doesn’t have one but will look into it!

If you're going to do this on a regular basis, get an infrared heater. McMaster Carr sells them. No breeze blowing and get an infrared thermometer. you need 400deg F for the powder coating to cure properly. For about 10-20min. The powder coating has to flow and crosslink the particles. Wood has a flash point of around 700F. Or use an oven to control the temp properly.

Hi Chalkline1505, thank you so much for your input. My husband has talked about getting a toaster oven for this purpose but ever since we started using epoxy we haven’t gone back to the powder paint. The infrared sounds like a really solid solution though because that powder is so fine and the blowing IS a problem with the heat gun. This is great information; I’m going to share it with Cameron. We have a lot of powder paint so I’d like to make use of it. This sounds a lot smarter and safer than what we have done with the heat gun. I’ve seen people use their laser to do it but it didn’t work well for us at all. Thank you again for sharing your knowledge and experience!

You should try spraying triple thick glaze over the whole thing when your done it's the best stuff ever made

Thank you! We used the powder paint on another project this week that I’ll post when it’s complete. We find that the powder paint is best for line drawings and thinner lettering and have turned to epoxy resin for larger areas. If I did this sign again I would want to try epoxy. The powder paint shrinks quite a bit so the bigger the fill area the harder it is to get even coverage, at least in my experience.
