Help Removing old SeaCraft Decal residue

[MM33]

Hey Guys,
I did the whole heat gun removal thing with my old decals on my 23 CC. I want to remove the old Glue Residue before putting the new decals on. Any idea of what to use? I am using mineral spiris now and its a nightmare getting all of it off. Any suggestions?

Thx a lot. Happy boating!!!!!

Lacquer thinner. Wet out a rag with it and apply, let it soften the residue. A single edged razor blade helps too.
