| Huey V77 | 05-Nov-16 05:02 | | First time I've used silcspan, didn't know there were two sides, got the wrong side up on some panels. |
| Don C | 05-Nov-16 10:21 | | I never knew that either. I first used it in the 50's and didn't know that either. I never could tell any difference though. There is a grain also, which can affect shrinking. |
| Don C | 05-Nov-16 14:46 | | Just went to the shop and tested it. Still can't tell. Therefor,not going to worry. Like DD said - after finishing you can't tell. Now sandpaper is another matter. |
| Skyediamonds1985 | 05-Nov-16 17:39 | | After applying the tissue -either side, but as the gentlemen said, shiny up or course side down- after your first coat of dope over the surface, lightly sand. The primary reason behind the sanding because the tissue naturally has fibers. These tiny fibers will tend to stick out after the first, and subsequent coats of dope. This sticking out of small fibers, or fuzz, is called "nap." Be sure that the coat of dope is thoroughly dried.... really dried before sanding. By lightly sanding, you're removing this nap from the surface. After each sanding, and before adding the next coat of dope, be sure to gently (and thoroughly) remove the left over fuzz or filings on the surface with a tack cloth. The second coat should also be followed by light sanding to help remove still smaller fuzz and so on. After about the fourth coat, you should be good for priming. But this is a subjective area for you to determine. Grain of the silkspan should go span wise from root to tip. Hope this helps. |
| Huey V77 | 06-Nov-16 11:09 | | One side is a wee bit fuzzier. Found out with the first coat of nitrate. We'll see how it works with a few coats of butyrate to fill in. |
