Shiny finish after using blue tack
Posted by David80 on Saturday, December 30, 2017 3:01 PM

I have started using life color acrylic and found that when masking with blue tack, a shiny sheen is left where the blue tack was.  I have tried washing with soapy water, but it still leaves a sheen, though not as bad.  I have also noticed a similar problem when using the Tamiya yellow masking tape.  In the past, I have used tamiya paints and had no problems.  I assume it is the Life color paint.  I was thinking of applying a coat of pledge, but if I did this for each color, the model would end up with 3 coats of pledge and might lose  fine detail.  Any suggestions?

How long do you let the paint dry/cure before you blu tac or mask?

this problem has occurred for two models now.  I allow at least 24 hrs for any paint to dry.  I am wondering whether it is the lifecolor paint as it has a very Matt finish.  Or maybe the pledge is a bit old?  I do live in a humid climate so maybe the humidity is affecting my masking products.

Pledge? I am confused. At first I read you thought about using it. Now it sort of sounds as if you did.

Me, I wouldn't dream of trying to mask over that stuff. 

If you didn't use the floor wax, I'd think 24 hrs might be adequate for the Lifecolor to dry enough to mask. I found an old article from one of the FSM editors online giving Lifecolor a good review and I think he mentioned masking fairly quickly.

Or maybe the Lifecolor is old and/or not stirred completely? Or maybe your blutac might be old and contaminated (that's a long shot).

Perplexing issue....

Sorry Greg I should explain model one I masked over the lifecolor, model two, I decided to seal the paint using pledge then mask.  I think I might buy some new masking tape as my existing tape would be a few years old.  It may also be not stirring the paint thoroughly as you mentioned.  If you shake lifecolor paint containers you get bubbles forming on the surface of the paint which can beproblematic when you decant into your airbrush, so I stir instead.  I hope to do some painting next week and try out the above ideas.  Fingers crossed!!

You seem to be doing things right. Even using Tamiya masking tape which is the best bet.

Sorry I wasn't able to help and I do hope you get this sorted soon.
