first of all the best tip is pick a hot day
luckily i did !
first thing if rebadging is to put some masking tape on the edges of the existing emblems
so that when you come to reapply, you know where they are to go, on the IS 200 digits i placed tape underneath and marked the gaps with a pencil(as they are made up of three parts) this was a mistake use an indelible pen, bacause the pencil will get rubbed out later

the emblems need to be heated up a bit to soften the glue
i used the sun , but a hair dryer also does the trick
(do not use a heat gun or in fargo`s case dont attempt to put in the oven
then get some dental floss (i used the peppermint flavour but spearmint does also work)
pull the floss behind the emblems in a see saw action,pulling towards yourself
the emblems will come off quite easy but they will leave the glue on the car



carefully pick at the glue and the bulk of it will easily pull off, leaving a sticky residue
i used a household stain remover, (a natural based cleaner for removal of biro, chewing gum etc ) allways test first on paintwork that is not seen!!!!
a quick rub of this and the glue was gone
a quick rub with t-cut to remove all that built up polish

and its now ready to apply the new badges, if you are just debadging stop now!
carefully line up the new emblems against the masking tape, be careful as once they grab hold they wont move again, then press firmly on

leave for a few days and polish the surrounding paintwork
and there you have it
