Sig Koverall
Hi there,
I'm thinking of building a Sig Smith Miniplane over this winter. I would like to cover it with Sig Koverall and have never used this material before. Have any of you used it? If so, briefly describe the process and results.
Thanks

RE: Sig Koverall
Type Koverall in the search box and you'll have DAYS of reading in front of you.
Koverall is a heat shinkable Dacron fabric. There are a number of different ways to apply it to your airframe. Each method has its pros and cons. You can use Sig Sticks It which is a heat activated glue applied to the airfame with a brush. Then cut the Koverall to size and iron it down.
You can also use Nitrate and thinner to apply the fabric prior to shrinking it with heat.
I'm sure there are other ways to apply it.
Once it's applied, you need to paint with your choice of paint.
There are as many ways to use Koverall, so read up and pick a method that make sense to you.
Good luck!

RE: Sig Koverall
i use Koverall and i apply it with Nitrate dope. (Stix-it works too, i just like dope
)
anyway, once applied, i start out with my iron (don't use a heat gun as it shrinks unevenly) set to 225* to shrink it.........if it needs more heat then go up in increments. 2 coats of nitrate thinned 50/50 brushed on will seal the Koverall and will also tighten it up a bit more. you don't want to go tighter than necesary. Koverall has the strength to turn some structures into a pretzel. just shrink it enough to take up the slack. (no sagging between rib bays)
once you have sealed it, you can put anything on it........
paint from Chip Mull (F&M Enterprises) will give you all the color you need, and it's a product that people rave about.

below are a few pictures of my projects covered with Koverall.
the Nieuport 11 has a pretty fragile framework (especially the tail) but handled the Koverall quite well.
