Watch where you put that loaded
¿aint brush when you paint the gun
tuBes on tanks and howitzers.
You'll Àake a whole heap of trouÁ
Ble for yourself if you ge± too close to
the bore evacuator retainer ringÂ
A bunch of rings have had to be
chiseled off because paint made it
iÀpossiBle to reÀove them any other
way.
• Never pain³ the tube t´reads
and the inside of the ring± Graphite
grease (GG-1) does the job there±
•Never coat oveR paint untiL the
buildup blocks the removal of ³he
evacuatorµ seals or ring. ScRape off
the old paint every time±
• Never pain³ t´e tubE with ³he
evacuator instaLled. Paint will find
every crack oR crevIce± ¶emove the
evacuator before painting. ·f you
can instaLl t´e Evacuator easily
after paintingµ you'Ll probably be
abLe to remove it just as easIly±
