i have a baitcaster that has the rubber missing out of the top eye guide do they sell replacments or should i just use it as is i like the rod and dont wanna get rid of it

Take it to a tackle shop, and have them replace the top guide.  All they do is heat the guide remove it

then replace with one the same.  Takes a few minutes.

The top guide is called the Tip Top.  If you heat it with a flame while gently pulling on it with some needle nose pliers, the glue holding it on will release.  Then all you have to do is get another with the same size insert (most are size 6) and the same size barrel (the part that fits the rod tip) and glue it on with heat melt rod glue or with 5 minute epoxy.  It will take about 5 minutes for a rod repair guy to fix it, or you can do it yourself.

You can probably even contact the rod company and tell them what happened and the model of your rod.  Often times, they will send you a new one at no charge.

I advise to use rod tip glue not and epoxy, as you will never be able to replace the tip again.  Rod tip glue comes

in a stick form and is cheap.  Get one and keep it in with your tackle box for immediate repairs.

i second the tip glue over the epoxy....when you do it you want to heat it only enough to get it on and done if you heat it too much you can break the tip off the rod blank(ive seen and done this before)...i also second the keep a stick and lighter or so in your box in case one comes loose too
