Hi, i was wandering why the reflections on this model are so blurry, i have a small wc the a need to aplly a section cut on sketchup to make the viewport fit my desires and some issues dont feel right..
Can this be the cause?
in this case my mirror shows something weird on the door material making unrealistic just where is the section plane
If you need a perfect result, remove the mirror and mirror your scene. It could work in your case. 
Right, the mirror only shows the direct visible part of the scene (screen space reflection). The rest of the scene is simplified shown and complex parts are general skipped.
maisprojeto , also kindly check out the following FAQ article which explains why you're experiencing this behavior:
Why are some of my objects/parts of my project not displayed in reflections?
If you have any specific questions regarding this subject, or in case something is unclear, don't hesitate to let me know.
Also, Sergio Fernando recently posted a nice workaround regarding this, which could help you further here.
Hi
interesting theme.
is this a thing that the new rtx technology can be solve?

Not really solved, but improved Enscape already traces rays for reflections even without RTX. It also includes textures in reflections starting with the current preview version when you render on "Ultra" setting.
RTX gives more power for such calculations, so it will definitely have positive influence on reflections quality. But please don't expect it to be a magic that will instantly give perfect reflections like in offline renderers.
