can it be used on shingles

Shingles on a roof, or shingles on your body? I'd suggest calling a roofer if you need to use this on your shingles. You can apply it to the shingles on your body then call the doctor in the morning. It will keep the shingles sealed and prevent leakage until you can get to the doctor.

is this food grade? or can i use this on ovens and BBQ grills? it will not directly touch the food but there is a chance that it will. thanks

I sent an email to Permatex regarding the use of this specific RTV Silicone product (81160) to seal a gap in a steamer used in my sandwich shop (gap between 300 degree F steam generator basin and steamer housing). Their response indicates that NONE of the Permatex products are certified food safe: From: Permatex - Product Application Sent: Monday, August 16, 2021 10:14 AM To: Pete xxxxxxxxxxxxxxxxxxxxxxxxxxxx Cc: Permatex - Answered Subject: RE: New submission from Product Support Form Pete, Our products including the Red RTV Silicone is not FDA or NSF certified for indirect and direct food contact or for drinking water applications. Don Sutliff Senior Product Support Specialist ITW Permatex, Inc. 6875 Parkland Blvd. Solon, Ohio 44139 Apparently, Permatex is focused on automotive applications so food safe certification is not something they are concerned about. There are other brands of RTV silicone sealers that are specifically high temp food grade , such as ASI 502 and Sil-Bond "Food Grade NSF FDA RTV Silicone Sealant Adhesive Red High Temp".

Is this compatible with differential fluid?

Yes, 81160 is used on the differential cover.

Can I use red etc for interior application on a tin ceiling with exstream heat from the Fl sun ?

this is over kill but yes... are you trying to seal a leek or just hold things up?? this is a sealer not a contact cement.

Very hard to apply, would be better with a caulk gun.

Great product, but make sure you've worked on your grip strength to get this out of the tube. I actually cut a fairly large application port into the lid and it still took all my strength to get this to come out smoothly. Additionally, the metal tube eventually broke in the process before everything was applied. It makes a fantastic seal though and I feel confident that my oil pan gasket replacement will last for the remaining life of the car.
