Tissue wrinkles drive me crazy

[pedwards2932]

I got the fuse on my Chipmunk covered and when I shrank it, it was perfect except 2 annoying wrinkles.  I tried a reshrink on the problem area and it seemed to help but not perfect like the rest of the fuselage.  How do you guys handle wrinkles in the covering.  I could cut them out and recover the offending section. I am using yellow tissue and it doesn't show seams too much.  Is there any method to get it to shrink a little more?

In my experience, once you have a wrinkle, it's there for good. One thin coat non-shrinking, cut it out and carefully patch with as little overlap as possible, preferably up to some structure. Then locally shrink and dope and carry on.

That is what I kind of thought.  At least with the yellow the overlaps don't show and I can cut it so the seams are over stringers and formers.

Depends how bad they are.  If the job's a complete mess from top to bottom; strip and recover completely otherwise I live with them. They irritate to start with, but I get used to them and there's always the chance that I'll make things worse instead of better if I try to fix them.

Well it annoyed me enough to cut it out and recover the cut out.  It looks good once I get it shrunk I'll post a picture to show what it looks like.  Should have took a picture of the wrinkle first.

Okay here is the repair and a picture of the fuselage covered and shrunk.  The wrinkle you see isn't the repair it is the section in front of the wrinkle.

How can one not love a yellow Chippy!?  Did you chalk the tissue?  The colour is very vibrant.

[pedwards2932]

No that is Hobby Lobby tissue.  Brand on it is Brother Sister.  It was 99 cents for 8 sheets.  They had a fair number of colors. It seems to shrink really well.  It has a pronounce shiny side not sure if that is good or bad.

One tip someone passed onto me was to lick the wrinkles

The saliva helps with some local shrinkage, sounds nuts but it does work and maybe worth a go before cutting out wrinkled section

If the wrinkle is local like that and the part is not likely to be subject to warping I use saliva on a very soft (and clean!) brush.  I then hold the affected area under a hot spot light and it will generally, in my experience, knock a wrinkle straight on the head...

I tried more water, alcohol, saliva, and heat to no avail.  Cutting a patching got rid of it.  Thanks

Using saliva was Crabby's favourite tip for wrinkles.  Like Andrew I apply my spit with a fine brush, not sure my tongue is sufficiently precise!

By the way, has anyone seen or heard from Crabby lately?

[pedwards2932]

I haven't seen any of his posts.  I'd like to find a can of Wrinkle Be Gone

..but then you never get to taste your model. Freshly covered glued on tissue is ..er.. well let's say an acquired taste
