Disable shipping for product with specific id

[kaminske]

Hello , I need to disable the shipping section for a specific product , it's a standard product but I need it to behave like a virtual one.
meaning that if that product exists by itself in the cart , when the user is checking out they won't see the shipping section at all. 

which files should I modify to achieve this ? 

Thank you

You might also be able to achieve that by setting thew product weight to some very low value like 0.0001 and the shipping prices apply for weights above 0.5

Thank you , I will try it and let you know if it worked
however I'm wondering if this will  hide the shipping section from the checkout process ? 
also , what will happen if that product exists in the cart with other products ?

It will not hide it probably by the cost of shipping for the respective products would be 0

Oh  , well I got the free shipping figured out actually  but it's not the solution I'm looking for  
I need the shipping section to not be visible when the customer is only buying this product , I'm basically  looking for how to add the shipping "behaviour" of a virtual product to a certain standard product , I tried commenting the shipping section in the shipping.tpl file and although that hides the shipping section , it also stops the checkout process from working properly because the customer can't advance to the payment section without filling out the shipping section ( this is the case for a standard product , for a virtual product this section doesn't exist at all ) 
Thank you for your help ❤️ , if you have any idea on how to do this  I can use some guidance as I'm not sure which files to modify to achieve this behaviour

this is the code I commented out , 
I suppose if it's possible to check if there's only the one specific product in the cart , I can add a default carrier and not show all this , that would probably work 
I only commented this part to see if it's the one I need to work on or not and apparently it is.
