Good question. My guess a Q-tip soaked in debonder?

Let me understand this right....
As the liquid glue creates a weld as it softens the stretched sprue, how does pushing it further into the gap create a smooth surface; let alone fill it completely without sanding?
I'm a little confused with this method and am trying to get a better understanding how you achieve a nice finish on the gap.

Yes Carlos! I use a cotton bud moistened with debonder and wipe away the excess CA glue, leaving the remainder in the gap. This cuts down on sanding significantly or even completely.

Stretched sprue and the black CA+debonder are two different gap filling techniques. Pushing the sprue down into the gap creates a stronger joint and reduces the amount of sprue sticking up out of the joint but sanding is still required. Generally speaking, I used the sprue to bridge the gap on plastic-to-plastic joints. The black CA was used where the resin nose butted up against the plastic fuselage or wings. I was looking for the strongest connection.

The bottom joint cleanup is almost complete.

I forgot to cut out the slots in the wing bottoms to accommodate the drop tank racks. That got me thinking about a better way... using magnets to attach the racks and keep the wing bottoms completely clean otherwise. So I drilled a couple of holes and dropped in the smallest of the magnets. These are 1/16" (0.0625mm) in diameter.
Image

The racks are BARELY thick enough to accommodate the magnets.
Image

Voila... detachable drop tank racks!

Love that idea - not sure it would work in 1/48 scale. BTW where did you get these tiny magnets?
Thanks,
John

Ok now I understand your method.

I got the magnets on EBay. I guess they are used by Warhammer figure painters.

Here is the wing after the magnets have been covered with putty.

Two magnets are enough to hold the rack + drop tank securely.

The tiny tail wheel is thoughtfully provided separately from the tiny tail strut. Curiously, the wheel is keyed into to a definite position even though the wheel is not weighted.I wanted to add flat spot to the tail wheel so I decided to incorporate an axle using brass tubing.
Image

The tabs on the strut are cut off and replaced with holes to accommodate the axle. And a small hole is drilled through the tail wheel.
Image

The key hole on the tail wheel, which is no longer needed, is filled in with black CA glue.
Image

These components can now be painted separately. When it comes time to install the landing gear, the tail wheel can be rotated so that the flat spot is in the right place.

Nice! Very nice! :hmm: And thank your for the clarification on cleaning up excess CA filler. How long do you usually wait before doing the clean up?

Thanks guys! You can clean up the CA immediately if you use activator. Another advantage for the impatient ones. Otherwise, just wait for it to be dry.
