Okay for your bottom the best stuff ive found is coatit its kinda a pain to put on but it works great, some people say that the spray in bedliner stuff works great also, but its expensive, wareas coatit is about 35 bucks make sure you follow the directions to the t, as for a good starter river in the area that you live would possibly be the puyallup its not very hard, or the satsop or lower nooch, the hump will be way to low, Id give the puyallup a try go from the bmx track in sumner to antons rest. gravel bar its about a 4to 5 mi float. email me if you need directions.
