Call to HP14 owners

I am looking at the same job as Ulrich in having to strip wings and fuselage. Instead of stripping I am looking at using my soda blaster as it will strip the paint while hopefully not remove the underlying contouring which appears to be still good.

I have used the soda blaster before for the gentle non destructive stripping of many aluminum parts but not on parts with bondo/microballon bases, anyone here have any experience in this?

I looked into soda blasting ,too , for the same reason not to remove any bondo. But have no experience with either methode . My friends in my German gliding club say there stripper don't remove bondo and just a week ago I met here in Whitehorse somebody who repainted DC 3 s and he confirmed that . He said if it would weaken the bondo you simply put a layer of epoxy paint over that aerea in question before repainting . Also I don't think on my wings is a lot of bondo other than over the rivets . About soda blasting I heared it is a very slow process and you use a lot of soda ?

Hi Uli I have a request in to join the yahoo hp group but waiting on administators approval. My bird is sn77 built in 1969. She spent most of her life in the Tehachapi/So CA area. She needs an extensive clean up/refurbishing but appears to be mechanically sound.

I've alerted the current owner of the HP-Gliders Yahoo Group. I have some admin privileges on that group, but unfortunately approving new members isn't one of them.

Hi Bob,
I'm into the group and already digesting tons of valuable info reading the posts.
Thanks
Dan

Hallo Ulrich

could that be an alternative to soda-blasting?

Not sure where one would get one of these flash lamps but it sure looks like a cool process for metal gliders.

It probably is but looks like complicated to set up to me.

Looks like a fun way to get skin cancer!
