Bottom of the polypropelene kayak.

My kid has run aground on his kayak a few times. The bottom of it doesn't look so hot. Isn't there some knd of wax that you use to fill in all the gouges in it?

what about this http://news.thomasnet.com/fullstory/457312

That's a little exteme. Isn't there something like a crayon used to rub along the bottom?

I don't have a lot of experience with the polypropelene kayak. maybe other members of the forum will answer you soon.

I use a little sandpaper and elbow grease to smooth out the scratches. Don't worry about the appearance -- that's the advantage of a relatively inexpensive plastic kayak -- they can take the punishment that a "newbie" dishes out.
I'm told that the scratches don't really affect your paddling speed.

I ended up calling the shop we bought them from. He pretty much said the same thing. Don't worry about it. It's a bummer tho, it looks pretty rough, but that's a kid for you. Still a whole lot of fun. Thanx to all for the input. Keep on paddlin!!

I use a fine grade sandpaper to smooth out the scratches. Poly is rugged, not meant to be fast, so disregard most of the gouges. They "come with the territory."

My husband and I purchased a Malibu two Ocean Kayak
in 1995. We used it for scuba diving and surface support in the rivers and lakes mostly. It sat around for a couple of years and discolored. Two years ago it got a puncture in the bottom from a boat trailer that it was slammed down on.

No one at any dealer would touch it to repair it. We found that if you use a propane torch and heat the plastic (very carefully) you can melt the plastic back together. We used this technique for scrapes and gouges. When we first purchased this boat we had hatches installed. We had kept the cut outs and used this extra plastic to fool around with.

We would not use this boat for a major trip, but it did the trick.

**We have since found that using a soldering iron, or a
heat gun will melt the plastic as well. This would be a safer more controlled way to do the repair work.
