I make a similar brew......... but instead of using the Italian Dressing....... I use salt water, vinegar, honey, lemon & lime juice and a bit of ginger and peppercorns.
I snapped one about 6 months ago. I contacted Shimano to get a new top section. They advised me they don't do that anymore and I had to buy a new rod. If you've only broken the tip between the 1st & 2nd eyelet, take it to a fishing shop and get them to put a new tip on it. You'll hardly notice the difference. Best of luck.
