- Sandpaper can be used quite effectively for removing excess P-tex, polishing edges,
- and base structuring. All of these things are good, hence I conclude that
- sandpaper is good.

- Also, you would normally do the base edge first (to make sure that the base is
- perfectly flat) , followed by the side, then a light run over the base again.
- Detune the tip and tail to taste (at a minimum find the contact point where
- the tip/tail starts to rise off the ground, then round off the edge from there).
- Finally debur using a stone. You can use sandpaper for polishing or detuning, but
- use a reasonably fine grain (say >300).

- Keep the candle very close to the base. This dissipates some heat into the
- base and will help you maintain a small clean blue flame. A metal scraper
- makes a good heat sink when you're looking for the next scratch to fill, and
- can also be used for removing any carbon which does accumulate on the candle.
-
- Before waxing you'll have to take down any excess P-tex. Wait for it to cool,
- then use a metal scraper, a body file (vicious but effective) or emery paper
- wrapped around a file (try starting with 100 grit, then finish with something
- finer).
-
- If you're serious then you can structure your base with sandpaper (after Ptex,
- before wax). Around 100 for very wet snow, 240 for dry, in between for in between.
- A couple of passes with the paper wrapped around a file or solid scraper - not too
- much or too hard or you'll end up with a concave base and have to file the edges a
- little more afterwards. Finish off with some Swix fibertex or similar to clean
- the loose fibers and leave a clean structure. Note that a stone grinder will give
- better results than this, but still its not bad for a home job.
