Craig, Do you use 220-grit for this initial sand as well?

For the initial sanding, yes. It's not so coarse that it cuts down into the fibers of the paper, but it is aggressive enough to cut the glassine layer. You can *raise powder* quite easily with 220, both with the white [Euclid] tubes and the old-style brown tubes... I've found 220-grit is also a good general purpose paper for doing not only the glassine sanding, but for the first balsa sanding and the first few primer sandings. Once the primer looks smooth, like after the second or third coat, then I switch to 400-grit, spray a coat, and finally switch to a 600-grit for the final sanding. I don't take it down any farther than 600, but I suppose one could for a laquer-based finish... Craig... |

"And now, to review what we've learned..."
Okay, I just spent awhile looking back at this thread, and I think I've boiled down the process to "Almost 3 (okay, 4) Easy Steps!"
1. Using 220 grit sandpaper, sand "naked" body tube. Quote:
2. Apply Fill N' Finish. Quote:
3. Sand excess Fill N' Finish with 220-grit sandpaper. 4. Apply primer to body tube, sanding after each coat. Now, I think I can patter off on my merry little way... --Yes? Cheers, --Jay Last edited by CenturiGuy : 01-15-2006 at 12:46 AM. Reason: Adding those annoying colo(u)rs for emphasis! |

Sounds like a plan, Jay. For catalog-finish models, you might repeat steps 2 & 3 "as needed". FNF sticks to itself reasonably well... Since I don't yet have a catalog to finish, I usually just apply FNF once...

Where to get this stuff (Fill N Finish)
I can't seem to find this Fill N Finish anywhere. All the shops around me have is the heavyier crap- E832, et. all.
There is one hobby shop that has a Hobbico product. It looks like spackle and has "Micro-balloons". Anyone know if this will work as well as FNF? Thanks, EB |

No, micro balloons isn't the same. I've used micro balloons mixed with epoxy to make fillets, but it won't work like Elmer's FnF. My FnF (light wood filler in a 16 oz round tub) is almost out. I was in Lowe's the other day and found it, but in a rectangular 16 oz tub now. It appears to be the same stuff.

I just got done filling a tube for my LOC Isis. I add a little water to Elmers Wood Filler and it works great. Also doesnt take very long.

No, he's saying the stuff from Hobbyco has micro-balloons in it just like the Elmer's FnF does, but you're right in that the FnF is much better for the job than the Hobbyco stuff.
