Question about Thule Atlantis 1200
How do I fix a cracked thule lid that broke when we drove it into our garage?
Use Devcon High Strength Plastic Welder Epoxy for Vinyl, PVC Piping, Fiberglass,etc. Line up the broken area as best you can and apply the mixed epoxy on the interior side as well as the exterior side. Do not overwork. It gets stick and lumpy fast. Apply it while it's smooth. With this epoxy you have about 5 to 7 minutes before it starts to get real sticky. Use the edge of a thin cardboard box to apply. I used a piece of a cardboard nail box I had laying around. Don't use your good puddy knife because you'll never get it clean. Let it dry - about 15 minutes. Do the process again until you've got it covered well and as smoothly as possible.
Don't be alarmed as this epoxy is a creamy color. After the epoxy has dried, use a fine sand paper to sand it off. Wipe the sanded area clean with mineral spirits. Then use a glossy black spray paint to touch it up. Coat it with the spray paint several times while letting it dry in between sprays. It won't be perfect but it will be waterproof.

Hi Fixya community, this question is dated, but for the sake of adding to the body of knowledge here... my story.
I have the popular Thule Atlantis 1600 which for reasons that still escape even the high volume vendors, has been discontinued as originally set up. A large (8 metres) branch fell on my Thule box splitting the upper carcass in many directions (both seams and field areas), in addition to the complete break of a front lower segment. I acquired the box for the features it represented, now broken, wanted to buy a new one --- wait... it is discontinued. While I was able to finally find one after much searching, I decided to try and fix the broken one. Well I have to say, it worked out great, and did not involve expensive epoxy, adhesives, hot air welders, or any of the methods most commonly referred to.
Thule's cargo boxes are made from ABS plastic. The same black plastic material used for your household domestic waste plumbing systems. Rather than use foreign (non-ABS) as your binding agent, simply use ABS. By keeping the joint material native, you are essentially re-establishing the continuity of the original material.
Take a small pieces of ABS pipe (any scrap will do, just ensure it's ABS -- will say on the side) and grind it down in shavings. I used a rotary cutting tool with a bit that looks like a common router bit for rabbit joinery. This resulted in very small shavings. Accumulate enough shavings and place in a small glass jam jar with a lid. I had to cover roughly 1.5 metres in crack length and found ABS shaving volume equal to a couple marsh mellows to be plenty. Here's the magic.... pour a small amount of Acetone into the jar and stir the contents (outside as it fumes) -- add more as needed just to get it to the consistency of carpenter's glue.
After you have bound the cracked segments of your Thule from the outside (I used rubberized packing tape as it great horizontal field strength but can be removed easily). The tape up doesn't have to be pretty, just ensure the edges are tight and tape is firmly holding it tight. On the inside, use a rotary cutting tool and any cutting bit to grind a trough directly where the cracks are. I when down approximately 3 millimetres and across approximately 8 mills. I left it rough to the touch.
Clean the trough with Isopropyl alcohol; let dry. Using a small paint brush (ones you find in elementary school water colour paint kits is fine) "paint" the trough with the dissolved ABS in your jar. The advantage here is the Acetone in the mixture dissolves the edge of your trough so both the slurry (your mixture) and the hard carcass body are naturally bonding. As you might imagine, the Acetone will evaporate leaving nothing behind but ABS -- as hard as the original, fully bonded to the original material. Once dried, apply additional coats to build up the trough to your preferred profile.
Remove the tape on the outside and you're set. You could apply some sealant to the outer surface of the cracked area, but I did not as keeping it clean to look at is difficult.

Supposedly heating a strip of similar plastic the size of the crack should work. i am going to give it a shot
