anti-rust protection for KIA Rondo 2011

I'm thinking about doing anti-rust protection for my KIA Rondo, since I'm living in Ontario/Ottawa, a very snowy and salty region. I read that even though the car is about 5 years old and is supposed to have good protection from rust still, it is a good idea to do anti-rust anyways.

I was wondering how difficult it could be do it yourself, presuming I have access to a car lift and can access the car underneath easily.

In a local CanadianTire store I saw a few "sprays" to do coating:
BLACK ASPHALT UNDERCOATING
RUST CHECK
STONE SHIELD

Each one is about 350-400g bottle, how many do I possibly need for Rondo?

PS. Or it could be easier/cheaper to get the car in a garage and have the do the coating professionally?

I would appreciate any feedback on this!

I use the Rust Check, its a great product. It stays oily and thin enough to seep into tight spaces, and stops already rusty area from getting worse.
I originally had a local shop spray the under-body (~$150) with this same product.
After that, I yearly do the problem areas like lift-gate, wheel-wells, and door bottoms etc. using the spray can.

A late response, but rustproofing your Rondo is easy. The backside of the rocker panels have several large rubber plugs that are easily removable. Although I have access to a hoist, compressor and rustproofing gun, I find it easier to use either Rust Check red spray can with the straws or Fluid Film with their flexible 360 degree spray hose that attaches to the Fluid Film spray cans. To access above the rear wheel wells, I just drilled a 1/2" hole in the rear door jamb, thoroughly spray and then install a 1/2" body plug. None of this requires lifting the car. Rust Check red, although excellent for inner panels, is pretty much ineffective at providing long term protection on exposed areas. For actual 'undercoating', a product like Fluid Film, Rust Check Coat and Protect (green can), Proform etc are much better options.

I have been doing my own rustproofing for close to 30 years and would never apply a rubberized or hard coating to the underbody of any vehicle. They rarely rust from there but rather from moisture in body panels, rocker panels etc. As Sorento5 alludes to, a product that creeps, remains 'wet' and self heals has always proved to be the most effective, although it does have to be reapplied every 12 - 18 months, climate depending.

I have also had Rust Check applied professionally over the years and can say with absolute certainty that you stand a much better chance of having a thorough job done by going DIY. The reason being is that although companies like Rust Check claim that their technicians are trained to know the inner design of all cars, they rarely take the time to move insulation aside, get in and around expandable foams and such that are sprayed in body cavities. Some shops are better and more thorough than others though.
