Hi
I am have just finished my vertical stab and rudder. Along the way I have had a few “oops moments” usually fixable. There have been a couple that have left their mark sort of speak. These include:
- An extra dimple where there should be none
- A couple of very small dents associated with riveting
- A very, very, very small “RV10 Vertical Stab Signature dent”
My question for the finishing experts is “to what extent will painting hide, cover up, make invisible minor imperfections arising from the construction process”?
Inquiring minds need to know ...

A year ago, I was in the exact same position as you. I looked at the mistakes, and figured I could fix them, and yes, you probably can. however, after a few days of looking at the dents and extra dimple, I decided to re-do the vertical skins. i called it a learning experience, and glad I did it. The new skins are not that expensive, and you will always know they are there, even if no one else can see them. And it is good practice before you start the horizontal. Trust me, you will not be the only one with a dented vertical skin in the corner of your shop.

Les,
Painting your mistakes makes them look beautiful . . . and obvious! I was in the same position and spent the time to fill any dents and smooth out smiley's using some filler. When I primed it looked prrrrrrrrrfect.

Paint won't cover it, but you'll be doing some filler on all of the
dings anyway, and that will. Sounds like it's time for the next
section. As for the extra dimple, stick a rivet in it, and later
you can fill the rivet and it'll disappear.

This is an OLD RV story. During the construction of HRII N561FS an extra
hole was drilled in the rudder skin. AGGGH...what to do?, what to do ?,
everyone will notice..... Well we just drilled an other hole on the other
side and filled both with rivets.
Sure nuff the RV inspectors (self appointed) looked over our tail feathers
at the fly-ins. (That's where they made their mistakes so they are looking
for yours.) They would point to the extra rivets with glee and ask "What
happened here ?". Our response was "Didn't you get the emergency AD, are you
still flying ?".
Only after they were deflated, we explained & we all had a good laugh,
GOTCHA.
I was told that one guy thought it was such a great gotcha he added the two,
used "pop" rivets and had a ball at OSH. KABONG Do Not Archive

Hi Tim
Thanks for the advice - I really didn't want to replace a skin. I was hoping
the Bondo solution etc would be acceptable. Anyway, Kearney's First Law of
Aircraft Repair states:
"There is a high probability of incurring a major problem whenever a smaller
problem is being repaired. Probability for the purposes of this law is
always unity".
Therefore, leaving well enough alone is always a viable solution.

What a painful coincidence and reminder. About 2 hours ago, I was on the last 10
or so rivets on my left aileron bottom skin. I was actually amazed that riveting
was going so PERFECTLY well, since it's a tight space to rivet in.
Suddenly, that's interesting, why is there a gap between the nose skin and
bottom skin over this last set rivet? It is a minor detail, but it's not
PERFECT. I'm sure I can make it PERFECT!
Now, the damn gap is still there, along with a nice smiley in my bottom skin.
It is amazing how some lessons have to be learned over and over again!

I am sure others have answered already, but without reading all of the replies, here’s my take.
If the extra dimple is an extra hole, then fill it with a rivet. If it is in a hole that didn’t call for a dimple, then you should dimple the other parts as well (or countersink) because flattening a dimple greatly reduces the strength of the skin around it. Often, in practice, dimpling one way then going back the other will weaken it enough that it breaks (or maybe it is the third dimple that breaks it). Either way, each time after the first that you stretch the skin it gets weaker.
On the signature dent, if you don’t leave it, people will just assume that you covered it up anyway. J
On finishing covering dings, that all depends on you. Some guys finish to the point where you don’t even see the rivets because the puttied them all over. Others fly unpainted and “let it all hang out”. So, the long and short of it is, you can cover anything you are willing to take the time to cover, but it can take a lot of time.
