I've got the cabin cover off prior to match drilling it to the Fuse and 

figured this would be a good time to smooth out the "varicous veins" 

left from the vacum bagging and to otherwise sand and fill the 

depressions/hills and valleys to make for a more ascethetic interior 

appearance. I merrily began this process using Bondo for the deeper 

'valleys' and a product called 'Icing' for the more shallow. John 'The 

Turbinator" Cox who monitors this grasshoppers progress to keep me from 

wandering too far afield from 'acceptable' practices. Noted what I was 

doing and in an offline e-mail diplomatically informed me that both of 

the 2 products I was using have histories of shrinking after 18-24 

months of use, and particularly when exposed to high (120F) temps. >  

! He sent me some pictures from some Lancair projects to dramatically 

demonstrate the results.



So my question is: What 'aircraft grade' filler are people using? And 

where did you obtain it from? I'd appreciate hearing experience 

particularly from anybody that's already solved this problem. The 

application I'm using it for, is definitely Non Structural, and cosmetic 

only, so I  don't need/want to use flox, epoxy and micro takes too long 

to set up to be able to sand. as I'm finding that it takes many many 

coats/layers of filler to get a smooth surface.



Let the games begin

Only at 120 degrees Deems, press on cause it is only 120 for about 10 minutes in the morning then it's way past that for the rest of the day  



I heard the Evercoat lightweight Rage Gold filler was good. I hope cause I used it on my HS tips but alas I did use lightweight cloth prior to a very thin coat.

Deems, recommendations from the local Aero Structures group here..

Hysol EA934NA or EA960F. Check with Loctite Aerospace group www.loctite.com

they should have a data chart for cross referencing applications.

A question for you..... how well did your cabin cover align with your

tailcone top skin F-1074? I seem to have zero gap at the very top but up to

.125" at the side skin junctions (F1073) All else seems to be trimmed

Thanks John, it looks like I need EA960F (Fast). now if I can find a 

place that distributes it. I can't say as how the cabin cover aligns 

because I haven't  put it on with the F1074 skin yet, I'll let you know 

what it looks like when I do.

For those of you new to composits there are two products that you should not

be without. Superfil by Poly-Fiber and UV Smooth Prime Filler.  The first is

a body filler but it is light weight and sands easily.  It goes on easy and

comes off easy.  This is a must, for get the bondo.  The second is for pin

holes in the composits.  It to works great.  Both are pricy but as they say

you get what you pay for. Spruce has both of them.

Epoxy also has a tendency to let go of polyester parts after a while and

I believe the canopy is made from polyester resin.  But I could be wrong

as I haven't seen my canopy in over a month.  I need to get my new

workshop done!

Most likely the canopy is acrylic.

Actually the canopy/cabin lid/top/fiberglass looking thingy isn't in an

RV-10 but the windscreen and windows are.

Guys,   

Hate to state the obvious, but any reason why we would not follow the guidelines in Plans Section 5T (particularly 'Prepping the Cowling for Paint') for all of the glass work??  Unless there is a compelling reason not to, this is what I have planned for the lid (this coming weekend).  

cheers,

You can use the West System epoxy (products 105 and 205) mixed with West System product 410.  410 is a very light weight filler that sands well.  Mix the product dry for deep holes and a little wet for final filling to minimize pin holes. for the final coat, use all three products as a liquid slurry to fill the pin holes.
