Skipping Gears
Just put it in 4th gear with the clutch disengaged and then go to fifth. Problem solved and no worries.
There is no need to double clutch downshifts on any car with syncros, just rev match. The entire purpose of a syncro is so that you don't have to double clutch (regarding usability anyways).

^^^this. thats why synchros were invented. now if you abuse them then thats your problem.
Exactly. Synchros were invented to equalize rpm's when shifting. If you are really old, you can remember cars with no synchromesh on first gear. Then you had to be standing absolutely still when shifting into first from neutral, and do it rather slowly. Double clutching could also help, but never shift down into first at any speed above walking speed. The synchros are meant to take a fair amount of punishment before wearing out.

Skipping gears:
I have seen many 6th gear sleeves that have been damaged.
The typical story is this: Stop light, 1st gear, engage the clutch, rev to 9,000 RPM, shift quickly to 2nd, rev to 9,000 RPM, same into 3rd, look down and find the car going 80 MPH on a city street and the engine noise is screaming, recognize that any cop is going to write a ticket. Shift to 6th quickly to lower engine noise.
Dragging the mainshaft speed down from 9,000 RPM to 4,000 when going from 3rd to 6th takes time. 6th gear has only a single synchro ring and it doesn't like it. It will grind if you are shifting hard and fast. By shifting hard the synchro ring does not have time to slow down the main-shaft and the sleeve will slip over the synchro and grind the gear. If the sleeve is ground enough in 6th then it will not slide the other way to engage 5th.
So if it is hard to get your car into 5th or 6th it may be because the sleeve is being damaged by skipping gears. Hope this makes sense.

I don't get it. Do people go around skipping gears in their civic?
I bought a car that has 6 gears... I think its a sweet deal. I'll be touching every gear as often as possible.
In response to another post. It does seem lazy, and the response to go and get an automatic seemed totally reasonable to me.
Drive it however you want... when it comes time to pay or tear the tranny down, be prepared.
While you're at it, get the Fram filter, 50 weight Pennzoil, and any old plugs that will fit in the hole.

Allright this seems to make some more sense...I am changing my mind
. Dont skip shift.

Just pulled a trans apart with a locked out 6th gear after a track day. Here's the deal:
5th and 6th share a synro sleeve, and a syncro hub. The syncro sleeve slides one way OVER the syncro hub to engage 5th, and slides the other way to engage 6th.
The problem is actually not a 6th gear problem. Its a 5th gear problem. The trans cannot fully come out of fifth gear, even though it may seem like it does.
The syncro sleeve gets its teeth mashed over on the 5th gear side. Since it is already on the 5th gear side of the hub, it will go into 5th.
When you go to shift to 6th, the mashed syncro sleeve teeth on the fifth gear side do not let the sleeve pass over the hub to 6th gear. The burrs hang up on the 5th gear side of the hub. If the burrs are light, you can force it into to 6th gear. Once on the road, USING 6th gear under full load will flatten the burrs and cure it usually 100%.
How does this happen? Skip shifting. Whether intention or accidental, the single cone syncro has little braking power compared to the double cones in gears 1-4th.
On the track, if you are wide open in second, and accidentally move the shifter into the fifth gear gate, you burn the crap out of the teeth. The speed variation is too great between the synro sleeve and 5th gear.
If you have done all you can to force the shifter and it will not go, disassemble the trans and replace FIFTH gear, and the 5th-6th syncro sleeve and hub set.
Close inspection will reveal saveable parts. This trans ONLY needed the synro sleeve.
