Kalyan-da, I've never tried it, but it seems like a liquid CA, not a spray.

Sir use Rubber solution ( Dentrite) for tacking the Cellophane Sheet to Balsa and shrink using sealing iron.

Apply a thin coat of dentrite to Balsa at all the places where cellophane it is going to come in contact. let it get tacky but not as much as for two surfaces with rubber solution to be stuck together. Let the applied surface remain slightly more sticky than tacky. apply cellophane sheet stretched. press is down give about 10 Min for it to get really dry than tacky. Now shrink it with sealing iron. I give the same effect as a clear covering film.


You can use a 10% thinner to thin it for easy application.

PS: the covering on my 28" Arrow build Kit from RCB is purely with Dentrite and Cellophane Sheet.

The following is a copy of my post on indiarc on 3rd March 2007


Here's my experience with the local variety -

- Gift paper - actually polyester film , available in silver , transparent , and a       myriad of bright flashly colours and designs. This is excellent. Its light and shrinks well. You have to apply a thinned contact adhesive on the airframe and and iron it on. If applying transparent or silver - it can be painted with normal enamel paints.
Take a piece of cotton , wet with acetone or Duco thinner and rub the surface before painting - this makes sure that the surface is clean and degreased. If you want the paint to stick really well apply Duco primer(used for painting cars) and use cellulose paints (used for painting cars). Best is is if the paint is sprayed on.

- Laminating film - almost the same stuff as above - but coated with adhesive on one side. Available in a various weights. Has lots of shrinkage and can distort light structures. Can be ironed on directly to the structure and can be painted.

- Vinyl plastic - not quite so easily available - coated with adhesive , comes with a backing sheet. This is heavy and rubbery - not good for open structures.
Good for covering sheeted areas. Heaviest of the lot.

- For the ultimate in covering cheaply, try the following - Cover with transparent polyester film . Shrink . Clean the surface with a degreaser. take strips of tissue
paper. make a watery paste of fevicol(like milk),add some shampoo or soap to break up the surface tension. apply on the poly film and then paint the strips of tissue with the same paste(use brush to go over the whole strip of tissue to remove wrinkles). once the whole wing/tail fuse is covered (tissue will be completely wet at this stage) trim edges with fine sandpaper. Use a hair dryer to dry out the entire surface. The resultant cavering will be torsionally strong and tough. Can be painted with any paint - using brush or spray. Try doing a web search on "tissue over mylar" , same stuff slightly different technique.

- lastly - for those who want to spray paint - there are guns available called "airless spray guns" which do not require compressors to run. In India there is the Pilot E88 - costs about Rs 1800, should be easily available in any city/town.

Have a nice day

Most interesting Rony. Something really worth experimenting with at leisure. I do belong to that era where I have used tissue/water shrinking/dope :D

Thanks so much for your inputs Sandy and Kalyan-da.
