Two possibilities.  First, did you prime it? The main function of primer is to help paint adhesion.  Second, there may have been mold release on the surface.  Most modern kits no longer use mold release that creates a problem.  But, it can happen.  Or, sometimes you get contaminents of other sorts on surface.  Washing a kit with soap and water before painting helps.

Better question is what tape are you using? Tamiya masking tape (or similar like tape such as Frog painter tape or blue painter tape)? Or are you using regular masking tape? Regular masking tape can pull off paint due to their stronger tackiness.

He already mentioned he used primer....

Washed and primed lol and the paint still didnt stick when pulling the tape off.

blue painters tape, then switched to tamiya tape on the second run through, stilled pulled the paint off...

I'm wondering about drying/curing time before tape application? Maybe?

BTW, even when using Tamiya tape, it's a good idea to detack it, which is a fancy term for sticking the tape on your pants a couple times to make it less sticky before putting it on model. .....you probably know that.

What paint and thinner did you use?

Hey Tanker, Sometimes there's no explanation! I know that if I spray the paint on too thick, it tends to not adhere as well. I usually spray on a light coat first and then cover that with a final coat. I tend to get better results that way. Others have suggested degrading the adhesive on the tape some to lessen its stickiness. That would help, as well, but it may be harder to get sharp lines if the tape doesn't stick at the edge really well. Barrett

What paint and thinner did you use?

 

Tamiya paint and tamiya thinner

Is the paint being pulled off the primer or is it coming off all together leaving plastic exposed ?

The paint I was trying to lay was Tamiyas Matellic Blue, when removing the tape it would pull the blue pigment up leaving the silver flake behind

Acrylic ? Which Tamiya thinner are you using and what ratio of paint to thinner ?

I finally got the car painted and it turned out alright.  Ended up using some testers MM acrylic paint thinned with alcohol which sprayed well.  Finally got smart and gloss coated the whole body and allowed it to dry for three days before masking out and laying down racing stripes.  All in all im happy, but holy crap its way easier to paint armor than cars lol

Be sure that all of the adhesion problems are the bond to plastic. You've tried a number of different base coats and found one that sticks.

I also would say that your drying times are not long enough. For a job like a car that will require a lot of masking, you really should go a week between coats.

Not always the solution, but it will save a lot of redo.

I'm glad you got it to work.

That's great, glad you got it done ! And ya for cars you gotta get all the steps in and give it time. And then you could probably still polish it with polishing compound in a week or two after that.

Sometimes wonder how the guys manage to do the weekend group builds and some other projects with the time requirements like this.

 

I don’t know either. Another reason why I don’t join Group Builds. I’m a slow builder and don’t want to be committed in a certain time frame to get it done.

I just finished the Weekend Group Build. I had some of the same issues but I was using regular masking tape in the areas where the paint lifted. Was using mostly Tamiya flat military colors on an RAF Hurricane and Tamiya tape for masking. Also did some of the painting by hand so masking was limited to strips. Maybe my using the mil flats helped keep any issues to a minimum. I'm not sure what others were using.
