Midnight Auto Parts Bbs Smoking

I'm reaching out for some advice on a couple of issues I'm dealing with. I've been working on my ride late at night, trying to get some auto parts sorted out, and I've been having some trouble finding reliable suppliers that are open past midnight. Does anyone have any recommendations for auto parts stores that are open late or have a 24-hour online store?

Additionally, I've been having some issues with smoking-related problems in my garage. I've been trying to fix my exhaust system, but I think I might have accidentally caused a bit of a smoke buildup. Has anyone else dealt with this issue? Any tips on how to clear out the smoke and prevent it from happening again in the future?
