				I had a dent in my rudder skin caused by an oops while back riveting.  I ended up getting it out, but may have caused more pain than I was expecting.  Now I have a bunch of wrinkles out about a 6 square inch area.   Also, I have a small 1" area that "pops" up and down.   
 
 The wrinkles are only really noticable when I look down the skin and notice the smooth aluminum and then the wrinkles - yuck!  As for the "pop", I figure this will go away when I close up the rudder.
 
 I pondered buying a new rudder skin - but I am probably over-reacting and don't really want to pay 77 bucks for cosmetics.   Not to mention drilling out all the stiffeners.
 
 My questions are:
 
 Will the wrinkles go away when the paint is put on - and possibly some filler?
 
 Does the small pop in the skin affect anything? 
 
 Thanks,
 Mark

				Mark... Yes, you're probably overreacting. Chalk this up to experience and
 better judgement for next time.
 
 I would recommend moving on. Worst case scenario is, in several months or years
 later, you will be in a better position to evaluate YOURSELF whether you need a
 new rudder skin. You can order it then, though, I doubt it. Most every
 first-timer has a blemish(es) in their rudder.

				Mark, you will hear all kinds of ingenious techniques to remove 
 smileys............however, lesson learned.  If you do end up with a quarter 
 or half moon.........rough it up with a stotch pad, then throw a little non 
 shrink filler it and move on.  Mine is coming back from the painter as we 
 speak.  I watched him go over ever little nick and rivet, yes, everything 
 shows up in black!!!!!  But not anymore:-)

				The rudder is known for cracking anyway, especially if you have stretched the 
 metal and it is working. You will see it after you paint, so my advise is to 
 spend the money.

 When I did that, the advice I got from Van's was to set the rudder aside
 and revisit it once the plane was done.  If it was the worst blemish I had
 at that time, then worry about replacing it.  Probably good advice.  Of
 course, I figured I needed to learn to do the work well, as well as to
 learn to correct my errors, so I 'fixed' my gaff.  When I was done with the
 'fix', I definitely had to order a new skin, as I had really trashed it. 
 (If you go this route, just get new stiffeners, don't bother drilling out
 the old ones...  you've got plenty of practice drilling rivets in your
 future!) 
 
 As to the 'pop' in the skin, that is commonly called 'oil canning', like
 the bottom of an old fashioned oil can.  I suspect that if your rudder were
 to do that in flight, you might experience some unplanned yaw.  Probably
 not significant in the grand scheme of things, but surely annoying.  To
 remedy that, I'd probably tweak the affected area to bias it towards
 staying concave and then apply a thin coat of filler to bring the surface
 back to flush.  This all presupposes that proper balance of the surface can
 be maintained, of course.
 
 FWIW, YMMV, etc

				I did the same thing.  Filled it with a mixture of micro balloons and  epoxy.  Took several applications of filler plus sanding to get  it just right but now it's invisible.  Depends how much you care about  appearance.
