can wd-40 waterlog a skateboard
if you use too much of it yeah it probably could however wd-40 is oil and oil and wood dont really mix so if it doesnt waterlog it the wood will be ruined but thats only if you flood it with it!
thats bull volcom it does not slow down your bearings its lubes them up so the ball bearing will ride smoother and it really doesn't weaken your deck unless its completly submered in it...dumbass
yeah it could mess up the deck if you use it try tnot to use to much
IT SLOWS DOWN YOUR BEARINGS AND WEAKENS YOR DECK
