I got my plane all covered using koverall for the first time ..it actually looked good until I started tinkering with it.dumb! I sanded the fabric on the fuse thinking it would make the cover line blend in the fabric.well dont say it!!!I learned as usual the hard way you can sand too much so I have to re-do the leftover.no biggie except I ran out of nitrate and stix it.my question is can I apply the koverall over the frame and use some sanding sealer or better a bit of buytrate dope that I happen to have .the frame was originally done with stix and then I brushed over the frame with nitrate waited until it dried and tightened the fabric.given I did that can I apply the koverall to the area being done over and use the buytrate dope to seal the edges ..I know one can go over the other just forgot which way it works.. help.

Been there done that,
Butyrate will go over nitrate but the Butyrate does not have very good sticking power, it is used more for shrinking. I would suggest getting some more nitrate and attach the new fabric.
I have been using nitrate to attach the fabric then use PolyCylic thinned 10-15% with water to fill the weave. It takes about 4-5 light coats lightly sanding after the 2nd coat and each coat after with 400 paper. Pay special attention to you seam areas and add a little extra PolyC to them and be very careful sanding where open structure meets sheeting, it is very easy to sand thru these edges.
If you do it properly the seams will all but disappear.
Good Luck!!

You can not put nitrate over butyrate but the opposite works well. Once you have butyrate on the covering, the only thing you can put over it is more butyrate.

thanks everyone I am going to hunt down some nitrate dope maybe even steal it from a club member.kidding!I did so well on the rest of the airframe but now I know to really not get careless on the seams..but I do like the covering with koverall.its really easy .my next project could be a waco lol.-I just sold my old one which was a pica ymf..but if I were to do one it would be bigger than 72 inches and candy red!

Koverall is a good product and just takes some getting used to on working with it, the results are worth the effort once you get it down pat. You can't go wrong with a Big Waco

i just ordered some tapes from pink-it. I am hoping the finished work will look great.I am painting the prject with latex using vallincourts instructions. yes if I do a civilan scale a waco could it.mine was nice but too heavy butit flew well and the new owner an accomplished builder is re -skinning it ..Koverall works fabously well at least for me and I bet I am not the first person to sand thru the fabric..but now I know better and its an easy fix..

You will like the tapes from Pink-It, I have used them on several builds.
The trick to the tapes is to iron them down as you go from stitch to stitch making sure you iron it down well on each side of the stitch. I found this method gives the best effect. Aftter the tape is down run the iron down along both side of the tape to assure the edges are sealed down.

waco what do you use to simulate stitches..someone gave me theidea to use monofilament fishing line and glue ut.what do you do on the bottom tape that the sitch is glued to?how long do you wait to brush nitrate or whatever over the tape.I am going to contact gary and have him walk me thru all this .I researched spacewalker photos and came up with a great color combo...

What you are seeing is the rib stithing. It is from Scale Rib Stitch, do a google search.
It is a self adhesive strip with the stitches on top. There is a paper layer over the stitching that you peel off after apply the stitching to the plane. You buy the scale you need then cut them to width. The rib tapes are over top of that and ironed down. I did not apply any dope over the tapes just a coat of primer before paint.
I bought rib tapes and perimeter tapes from Gary for my Waco. I also applied tapes over all the fuse stringers just like the full scale. Adds a nice little touch.

hi waco.it takes me a while but I get the process now.I may use the glue technquie or I may just use a monofilement line that is consistently the same.I like the idea I can iron them on and not have to add more weight by using an ahesive to keep them in place.once this is done and I bet its soooooooooooooo tedious I hope to shoot some paint and bring it together.my radio is all done ..I have a remote igntion from world expert that I plan to use.I have a color combo that I like so maybe over the next coupleweeks it will be completed so I can fly in a septeember fun fly.. dennis

I have used glue stitches with good results on 1/4 scale, it is tough to get them the same size. A little practice and it is not too hard. The key is to slightly thin Elmers white glue with water and use a syringe with a 18ga needle. it takes longer to mark the location of the stitches than to put then on once you get a rythem going.
The tapes from Pink-It go very well over either type of stitches.
Hope this helps!!
