Gents,



Does anyone have a suggestion as to which body filler is best to use on plain aluminum, where holes can not be drilled in the fuselage, to smooth out minor dents?



Thanks!

Moe

Pro seal fuel tank sealant smoothed with a finger dipped in MEK works well.

Pressurize it to about 30PSI!

It takes too much bondo and then makes the airplane way too heavy to make it 

useable again. And you need STRUCTURAL bondo.

Moe,

There is an epoxy filler called SUPERFIL by Poly-Fiber that is a

corrosion-inhibiting filler designed to adhere to bare alluminum.

I have used it for about ten years with excellent results.  Dry time is

longer than bondo but it is easy to mix and shape with excellent adhesion.

Available at  Aircraft Spruce in Corona 877-477-7823.

Folks,



At the risk of sounding like I am trying to teach somebody to suck 

eggs, can I suggest that, for anything more than minor cosmetic 

damage,and I really mean minor,  and anything with a score as part of 

the ding, you should consider it in terms of damage limits, ( not 

much in the older Commander manuals) and AC 43-13A/B, and proceed 

accordingly. Small doubler plates, suitable fitted on the underside 

of "panel beaten" sections, are really easy to do. A ding means the 

metal is stretched, all the usual methods of shrinking the plate 

(skin) do not restore the original strength.



Needless to say, never use bog ( English for bondo) on any control 

surface. The results of flutter from unbalanced controls is not pretty.



Anything you use should be safe on aluminium, the results of stress 

corrosion  ain't pretty, even "ordinary" surface corrosion, 

especially inside lap joints can ruin your day, not to mention your 

bank balance.



We have had altogether too much experience with hail damage recently, 

and have some very nasty disputes in progress with insurance 

companies, who will not accept that, on the type involve, the fwd. 

spar/leading edge structure is, in fact, a "box spar", not just a few 

ribs with a bit of sheet wrapped around it.



Cheers,

Bill Hamilton

Commander Drivers,



Thanks very much for all of the information on dent filling.  Here is the deal...Recently I picked up some ice very quickly, and when the hot props went on there was a little ice slinging episode which knocked our some body filler that had been previously installed.  The dents were no worse than before, and were in the rounded part of the top of the fuselage (part of the pressure vessel and above the thick panel which is made to take the hit).  Problem was, three pieces of body filler, about the size of a quarter each, missing do not look too good.  Over the week end the Poly-Fiber Superfil Epoxy from Aircraft Spruce and Specialty was used.  There is actually an STC for its use.  It appears to work quite well.



Regards,



Moe
