I can not remember the sticking up the bushes with CA however I use two sizes anyway only as a guide since I measure every one. I cut the steel bushes under a bit. My one coat of CA never lets me down I put it on at half full speed its never flooded on. My latest pen proves the point. One coat of CA followed by an activator spray immediately followed by a smear of stick brown polish. You can spend all day if you choose finishing. I have that pen in my hand as I write looks and feels very natural. I have an enormous tin of Barrier Reef Carnauba Wax 100% grade car polish that would last a lifetime I bought at a car place closing down I use occassionally Made in the good ole USA. The simple lighting I use kills the glare I could have from the finish I try to give detail not reflective pics.
Note the top of this pen was faceted so it the CA was applied with the lathe at rest also no worries. I did research carefully to find the CA I could absolutely rely on. Mine is called ZAP Zap a gap Medium from the USA. The activator Hafele from Germany.
KInd regards Peter.
