I put a spool of pline in one of my boats compartments and we had to get the boat worked on. I forgot to take it out last summer before it got worked on. It baked in the compartment for two months before we got it back. Is the line still usable, or should I just trash it?

I would replace it... Pline at 8$ for 300 yds...

That kinda heat? That's what I would do.

I agree. I'd just replace it.

Just grab it with your hands and tug a couple sections. If it breaks, it's no good. Otherwise, good to go.

I buy the filler spools of Seaguar Invisx and Abrazx for leaders material to my braid, it sits in my tackle bag, a bucket with seat, the back of the truck under the cap, you name it, below zero to 100 degrees, but still will last me 2 or 3 years and seems to be as strong and abrasion resistant as it was when I bought it,,,,,,but I always keep it out of any sunlight!! UV is your worst enemy. Never used P-Line but would do as Tiwithay suggested, if it isn't,,,,,, I would switch!

What P-Line ?  it´s not the same nylon than FC, while line may not be in the best of shapes after such treatment while FC or copoly will have suffered nothing.

The heat will def take some of the strength away. Even if your not fishing a tourney, I would still replace it cause you never know when that 10+ will hit.

I also use Berkley Big Game and it gets the same treatment with no ill affect, I use the 1 lbs bulk spools and after 2 or 3 years still have no problems, like I say they are always in a tackle bag, boat compartment, bait bucket, whatever but always kept out of daylight. Never really worried about keep it air conditioned, been this way for 20 years I don't worry about my line on my reels as they are all 832 Sufix, before that Fireline, totally unaffected by heat, UV, water, you name it. But always start a day with new leaders 18" to 12' with my old drug around spools of Fluoro, or mono.

It is c21. I fish tournaments every weekend now and the line is only $5 so I will definitely replace it. Probably go with fluroclear. I love fluroclear. Casts a mile and super easy handling.

Just grab it with your hands and tug a couple sections. If it breaks, it's no good. Otherwise, good to go.

Right

 

I have a few reels spooled with mono or copoly in my hot Florida garage, they are just fine and have been there several years.
