The company I work for has invested into a dedicated airbag seam repair machine because we know are industry needed a solution for this issue . Now you dont have to reject work because you can't fix a blow out seam. We have already started using our machine to make replacement covers that are not available or just need an outer bolster repair. There is way more to discuss on how the machine works than I can write if you are needing our service. But there is now a answer to this problem. Please be patient with us we are a small shop but we are here to help out our fellow tradesmen. I will try and post a link to the web site. Any questions just ask or i can give you my phone number for questions. https://airbagsolutionsllc.com/
