Would this work as a sealant on the abs fitting that inserts into the rv poly holding tank outlet and has a hose clamp?

Re UV protection. It is widely used on RV roofs so presumably is at least UV resistant. That said, I've found that it lasts only about 3 years on the roof of an RV that sits out in the sun. It is necessary to check it annually and rough up the existing material and add more where cracks have developed. The cracks are in part from expansion and contraction of the underlying parts, but do work their way up through the Sikaflex 221 and result in a leak of the crack is not repaired. I inspect my RV roof annually and usually need to do some repair to the older Sikaflex-221.

Is this suitable for bonding a window into an aluminium u-channel on an rv? also, can i remove it if need be? thank you

Precisely the application to which I put the material to use in - sealing RV windshield to aluminum and fibreglass. Has worked flawlessly for 4 years. Easy to remove before cure; extremely difficult to fully remove after cure.

Can someone verify if inventory issue fixed, ordered two blacks and received both white (stamped inside bottom of tube)

I have always received the correct color ordered (fulfilled by Amazon). Contact the Seller directly (or whoever is fulfilling an order on their behalf), to confirm inventoried colors. I would request a refund for any product that is not what you ordered.

Do you recommend this for filling in concrete floor cracks? Will it self-level?

Not sure on concrete it may hold up but it will not self-level
