How do I fix the initial text display of a product to look like the display when it is clicked on?

I purchased MarketPress eCommerce to see if the upgrade would allow greater text display control. An example for the site is:
http://freezeplugfactory.com/store

If look at first product ending with 3400, it will have a paragraph like description. If you click on product to get:
http://freezeplugfactory.com/store/products/freeze-plug-kit-to-3400

You will see the description broken up in lines.
The client would like it to display like this. I have tried simple
</br> in between sentences to no avail. I have also tried to bold certain parts of text.

Is there anything I can do here?

Thanks... Gavin
