Save custom data to ('checktout/session') when product added to cart and remove when removed

So i need to add custom data for each product when customer adds it to card and remove it when customer removes from cart.
What i have done so far was creating observer that fires up when customer adds product to cart, but it doesnt save my data in global ('checkout/session'). In observer i can see my custom data saved. 
This is the code in observer:

        $quoteId = Mage::getSingleton('checkout/session')->getQuote()->getEntityId();
        $quote = Mage::getModel('sales/quote')->load($quoteId);

        $carDetails = Mage::getSingleton('core/session')->getCarDetails();
        if(empty($carDetails)){
            $carDetails = 'No Car in Search';
        }

        $quoteItems = $quote->getAllItems();

        foreach ($quoteItems as $quoteItem){
$product = $quoteItem->getProduct();
$quoteItems = $product->setCarDetails($carDetails);
echo'<pre>';print_r($product->getId()); echo'<pre>';print_r($product->getCarId());die(); }

Any help or suggestion would be greatly appreciated. 
If someone knows better way of doing this, also greatly appreciated.


p.s. i need to save this data later on as extra or note to Invoice or Order.
