Can this be used to seal around accessories for a kayak

Yes, it will work well in that application.

Can this be used to permanently seal a car sunroof

This silicone sealant will seal almost any two materials that are CLEAN and DRY together. Try gently cleaning sunroof surfaces with rubbing alcohol, let dry, then seal your sunroof with silicone. Surfs Up

Can this be used around the base of an RV toilette?

I would say yes. I used it for my bilge pump going thru the tramsom of my boat, which is submerged, and it hasn't leaked after several years.

I plan to make a an acrylic shelf. Does this dry clear? And holds acrylic well enough for light weight bearing loads like diecast cars and figures?

This will dry white. This is a sealant and not meant to bear weight.

Convient size

Works great in many areas and a convenient size vs tapping open a huge tube for caulking gun. I use for areas always wet needing great adhesion. I recently even used in my SS garage sink drain instead of plumber putty since using PBW seems to slowly eat away at that putty. So far no leaks! uses limited by imagination.

Works both above and below the waterline

Exactly what I ordered. I have used this silicone many times before and I believe it’s just as good as 3M‘s silicone at almost half the price.

Perfect solution to bathroom

There was a gap between bathroom tub and floor tiles that was concerning for moisture. The nice thing about this product is you don't have to be a handy man to use it. I had to cut the tip a few times to get the desired amount out. It did require some strength to get it out then I just gently blended it into the gap. It dries clear which I love. It's also waterproof. I would recommend wearing gloves as I was overzealous and forgot. It's really hard to get it off your hands. WEAR GLOVES!!!Maybe manufacture could put in a small tool to help blend it in.Other than that it was just what I needed. I should have read about how to store it after use as this purchase may end up being a one time use if it dries out. I would definitely but it again if need be.

Perfect for a Black Sink!

I installed a black sink and there was a small gap between the sink and countertop. I taped both the sink and countertops, filled the gap with the caulk and smoothed it cleanly with my finger. It adhered to both the composite sink and countertop filling the gap perfectly. It was so smooth and easy to use, exactly as needed!
