Blu Tac Leaves Greasy Residue on the Model

For both blue-tac and any masking tape I use that leaves goo, I generally find rubbing (isopropyl) alcohol works well.  I use primarily enamels and lacquers. If using it on acrylics, be sure it has completely hardened.

I use White Tac as well, Blu tac is to gritty and hard to get it all off.

never heardof panzer Putty till now, and for 15 quid, i'll stick to white tac.

I don't care for Blur-Tac for that and it's justa little too sticky. I still use the SillyPutty but don't really care for it's light holding power.  For me, It's better that removing paint or the residue. On one build, I just sprayed over the residue with a clear coat and it seemed to go away. I don't recall if it was gloss or flat.

I haven't looked into Panzer Puty yet I'm sure is just right. But like Jon_A_its, I too am a cheap-skate.

BlueTac can sometimes react with paint & leave residues, so I use White-Tac instead, slightly less tacky, & hasn't yet gone icky..

Try rolling a fresh new lump bluetac over it, as I think soapy water tends not to work?, therafter something lite like Medea airbrush thinner, provided it doesn't marr your paint.

Silly Putty is hard to find in the UK, & Panzer putty is too expensive for what it is for my cheap-skate mode...

Never had a problem with blu-tack leaving anything behind personally, guess soapy water would work. Have a look at Panzer putty or similar, it replaced masking with blu-tack for me.
