im no retainer specialist but here are a few things to consider..
you might try superglue. you will need an accelerant so it cures immediately.
personally i just like to use monomer. they do sell superglue accelerants in a spray bottles but im not a fan. its just something extra to buy and when you spray it .. it gets all over everything.
if you need some extra strength for the wire you are trying to hold in place take a small round burr and drill a small hole on each side of the wire into the model. (this will add mechanical retention instead of just chemical). then fill that with superglue (and around the wire) then use a tiny drop of monomer and it will setup immediately (gets hard as a rock) holding everything in place. also now days superglue comes in all different thicknesses. dont use the supper thin stuff that is runny and gets all over the place. i like a medium body glue and they do sell it in a bottle with a brush. (kinda like nail polish). thats the one i like to use for this application. i use other types for other stuff. dont get stuck (no pun intended
) and think you have to use the same superglue for everything. its cheap. try different stuff.
i have seen some techs use a hot glue gun. for me its a bit slow to set up and i dont find its ability to hold to be dependable.
as far as not having an "official" boil out.. you dont really need one for that?
a great alternative is having an
instant hot water unit installed under your sink. i have one and have found it invaluable. i use it all the time. no muss no fuss. gives you instant scalding water anytime. great for wax cleaning.
but if you want the ultimate non boil out solution. some day think about getting a steam cleaner. but.. you have to get one that is adjustable. it must have the ability to make the steam wetter or drier. dry steam is great for cleaning marks off the dies in a c/b lab but is almost useless for wax cleaning. the steam needs to be wet for wax cleaning.
bego makes one and
reimers makes one. bego is $3500 plus and its not that great in the longevity dept. its pretty on the outside but doesn't really have any balls. the reimers unit is the one you want. its about $2500 and its a wax cleaning machine. and comes from a great company.
good luck.
