| Good job, Brian. Now I'm going to push a little harder. Be sure you work on the leading and trailing edges to get them clean and smooth. Any little bumps anywhere will give you fits and wrinkles when you cover again. Try to get rid of all the white. heck my next picture. It's a handy little sanding block that let's you get a lot of places. Again, that's a great job. It's tedious work. |

| Sounds good to me. |

| thanks sky, it would be a shame to let all that good work go to waste. the model masters little paint jars that I airbrush, work pretty well so i'll probably use that to prime the plane. |

| By the way, glad you're trying it again. If it'll be of any consolation, I've been there a couple of times myself. I believe I speak for everyone here. |

| Fantastic job stripping the tissue!! Are you making a "proof of concept" dummy section of a fuselage in similar shape? Try out the covering, doping, and painting on the prototype before applying the results on the F-5. The challenge is the covering with the flying surfaces already in place. Not easy, just a little bit of creative work. Looks really great!! |

| There are several possibilities: incompatibility between the enamel primer and the dope, the enamel was applied too thick in one-heavy-coat of spray, or the second coat of enamel was applied before the first coat was completely dry (like at least 12 hours) because if not completely dry, the 2nd coat will act as its own paint thinner, and finally *and this is what happened to me* is that there were not enough coats of dope applied to the silkspan to completely fill in the weave. When this happens, the silkspan has pores that allow the paint to dry unevenly in the extreme. The reason I mentioned that last part, is because I can easily see that the plastic intake is evenly coated and I know some of the dope must have been applied over a small part of that plastic where it meets the rest of the intake ducting. Its a nice, clean separation. So, my guess is that there were not enough thinned coats of dope to fill the weave of the silkspan. Bad news.....is, well, you may not want to hear it. Good news is: that its not as difficult as you might imagine. It actually comes (peel is a more accurate description) off very easily with judicious amounts of dope thinner..... Sorry. Please don't shoot the messenger... |

| thanks for the help don. that's the first time it happened to me and to do all that work and probably have to re do it. |

| My first thought was Oh crap! I think I'd go with 320 grit first and a very light touch. Be sure to use a block where you can. If that cleans it, good, but if it's still not sound that could mean it will continue to flake. In that case you might want to sand it all off carefully and recover it. See who else chimes in first. |

| thanks julinick, I doped the tissue twice before spraying the primer. is 200 grit, light enough a grade to sand? the plane is not planked it's stringers. |

| Did you happen to seal the tissue before you primed it? On my F-14 Tomcat, I sealed the silkspan with Krylon Clear Finish. I applied several LIGHT coats and sprayed 2 coats of Krylon Primer. I think this might of happened because the tissue was not sealed and to much spray in one area caused it to cracked. Have you tried to sand it down with light grit sand paper? |

spray can mishap. when i applied model master enamel primer spray can it left a flaky finish when it dried. i tried brushing it off with a tooth brush, but that didn't get it all. any other helpful solution? |
