learn how to spell please
its spelled "caulking" not "cocking" lol

there are also many types of caulking material
this page explains the pros and cons of each of them

if window is not fixed and can be opened, then you should also consider weather stripping

The best caulking silicone is by G.E. (General Electric) which is the choice of numerous contractors because it lasts up to 10 years but it does cost more ($9-$12 a tube).

A couple of window contractors I have spoken to in the past use polyurethane caulk. They say it is the best and swear by it.

Whichever brand you get be sure to check the best before date.
I bought some GE stuff from Rona last week and it was half cured already. The best before date was cut off on the bottom.

I don't see a best before date on Mono Ultra: J/5 5127553

Take it back and get a refund or replacement. That kind of shifty business practice is unacceptable.

GE Silicone II was recommended at RONA whereas Mono Ultra was pushed at Home Depot, what's the difference?

I was told Mulco Flextra thermoplastic can be used in any temperature, has anybody had any experience with this product?

Check out this video, it may help

ahahaha nice video
perhaps this could be moved to Home and Garden forum to get more attention

what kind of climate are you in?
are you in Ontario or BC or where abouts in Canada?

if your house experiences severe winter, use the best silicone products you can find

for polyurethane, u have to paint it to protect it from UV rays if using it for exterior

I've been doing heavy home renovations for too long ... and for most caulking jobs have boiled it down to two ... then I found this site which matches my personal preferences exactly.

You won't go wrong ... http://www.factsfacts.com/MyHomeRepair/caulk.htm

If your skylight isn't terribly visible, I'd go with the Silicone II

Matches my experience. Could never figure out why GE can't make the best caulking for both conditions, and DAP can't either.

They are pretty much the same quality, they waranties don't mean jack. The warranty never covers damages done to your home due to bad quality, therefore why do you need a money back on 5-10$ ???.

Forget the 10-20 year warranty hype and get whichever KNOWN brand is on sale (Mono, Dap). Always buy the interior/exterior type. For windows, it will be specially marked for that use.

The GE Silicone II will perform better but it is silicone, a mess to use (setup a 1/8" or whatever gap between strips of masking tape; lay the silicone in between and use latex/vinyl gloves to tool it into place) and it is non paintable

The DAP is 100% latex (cleanup in water) and paintable but I notice that in some places where I haven't painted it, it has discolored (or picked up the "dirt"). I also suspect that it won't perform as well in bathrooms (really high humidity, inside showers, etc) as the Silicone II.

but, between the two of them, you have all the caulk you will need for 98% of all jobs.
