As of September 19, 2025, Phase Hangar Resin is now operating with live inventory levels. This means that if you order something that is in stock, I will have it shipped out much quicker. No more waiting weeks and even months to have your order fulfilled. This is a benefit to you as the customer as well as I, the producer. It removes a lot of stress and anxiety while filling orders. The other good thing is that I will be updating some parts on a daily basis to continue to have a well stocked shop. I absolutely appreciate your orders and even your views on my website, even if you don't purchase anything. Phase Hangar Resin is a USAF Veteran owned and operated one man company which prides itself on quality products at a reasonable price. If you are a distributor in Europe or the UK and would like to carry Phase Hangar and/or Flight Line Resin products please email me direct at Phasehangar@gmail.com for terms and conditions.Also, if you live in Europe and/or the UK and your box is returned to me as refuse or not claimed you will be charged with a 50% restocking fee upon refund and will not be credited for shipping. I have no idea why it was refused or not claimed so I have to assume you changed your mind for customs or other reasons. Please be sure to follow us on Facebook and Instagram for regular updates as well.
