heavey duty portable car port or spray bay

Portable spray bay ? - fine if you have a flat calm day with a absolutely zero wind pattern, on a flat made - dry & dust free surface and no dive bombing insects within a 10 miles radius - believe me I have tried on several occasions and never again !!! Painting a vehicle is technically challenging enough when you have the access to all the right equipment, conditions, atmosphere & building - yet alone trying to attempt it in a tent. That said there is one or two companies out there that do manufacture a portable spraybooth with extraction system etc - however they are in the several £k price bracket

I have something similar. Unless you can literally concrete the posts in, or bolt them down, it will at some point end up in a neighbours garden upside down

I use something not too dissimilar to that to do smart repairs at local dealerships. 10 mins to set up and 10 mins to take down. It keeps the rain and wind out which is the main thing. We have some heavy metal weights that sit over the 'feet' and some wrap around bags filled with sand that strap to the legs and sit on top of the metal weights. It's also hooked to the nearest fence or the van wheels. It's surprisingly stable, even in the strongest winds. That one in the link is about a quarter of the price but doesn't look too bad for the money.

And then 18 months later this is what I came home to!
