and after you have scraped.... i suggest you get a stiff bristled brush; not quite wire wool, but say somethign your grandpa uses to clean his dentures with!
then use the brush to score tiny lines in your finished wax job, that run parallel to your edges. this helps to create the water conduit channels referred to in this threads initial monster post. (oh i also and finally use a cloth / rag to lightly rub / brush off any loose scrapings / bits of crap)
my nitro has a carbon base. i use graphite wax on it.... but what for the fat gouges? is p-tex really all that can be used?
Just coz you don't understand it
Doesn't mean it makes no sense!
