ARGGGGGHHHHHH (David Saylor) ________________________________ Message 1 _____________________________________ Time: 07:05:24 PM PST US From: Tim Jennings Subject: RV10-List: Dents in VS Skin from flush set..... ARGGGGGHHHHHH Alright, I was making great progress and then used my non dominant hand to rivet the second side of the VS skin and managed to make about 6 dents in the skin along the front spar before I realized the poor form and consequent mistake. They are absolutely noticeable. In a "done is better than perfect" moment I kept riveting once I was cooled off about the mistake so that I would have a finished part. Now I am looking for a filler that I can use to make the dents go away before I drill out all the rivets and try a second time with a NEW skin. Is there anyone out there or "has a friend" who has made a mistake like this before and lived to tell the tale while using a filler that has stood the test of time? I have lots of experience with Bondo from my motorcycle painting days and know it is NOT up to this task. Flex/expand/contract/vibrate, all things that would separate brittle Bondo from the skin making it unsuitable for this task. I am hopeful there is a better product out there for aviation before I crack out the drill and try my hand at a second skin? Thanks, Tim ________________________________ Message 2 _____________________________________ Time: 07:24:34 PM PST US From: Brian Lester Subject: Re: RV10-List: Dents in VS Skin from flush set..... ARGGGGGHHHHHH Leave it be, at least for now. At least that was my decision when I had some =9Cimperfections =9D. Don=99t worry about fixing dents if it=99s just a surface imperfection. Build on an d learn from it. When you get to final assembly (or close to it) look at it again with a fresh set of eyes and decide if you need a new skin or if epoxy and micro is fine. (Heck if you get it painted ask he shop to make it look better if you are concerned. ) Just my 2 cents. -Brian On Sun, May 20, 2018 at 10:09 PM Tim Jennings wrote : > Alright, I was making great progress and then used my non dominant hand > to rivet the second side of the VS skin and managed to make about 6 dents > in the skin along the front spar before I realized the poor form and > consequent mistake.

ARGGGGGHHHHHH From: Kelly McMullen Very good advice. I believe one filler that will work is "Superfill", which is a mix of epoxy resin and high percentage of micro-balloons. Available at AC Spruce and similar vendors. On 5/20/2018 7:21 PM, Brian Lester wrote: > Leave it be, at least for now. > At least that was my decision when I had some imperfections.

ARGGGGGHHHHHH +1 for superfill. It's the "Cadillac of Bondo". Only downside is that it takes a lot longer to cure than polyester--count on at least several hours. Those dents are like the first door ding on a new car. They hurt the worst but it you'll get past it. Learning how to fix the mistake is pretty valuable. --Dave On Sun, May 20, 2018 at 7:02 PM, Tim Jennings wrote: > Alright, I was making great progress and then used my non dominant hand > to rivet the second side of the VS skin and managed to make about 6 dents > in the skin along the front spar before I realized the poor form and > consequent mistake.
