painting questions

[Darth Domain]

I had begun painting the black sections on my second rubies upgrade yesterday. I had used fine line masking tape to do the curved areas etc. i gave the helmet three goods coats with 20 mins between coats then began removing the masking tape and to my horror the tape was pulling away the gunmetal, the gloss black and even the primer underneath. Now, i was a little piss*ed at this but thought oh well, back to the begining.
So i have had to rough sand the whole facemask again and will need to re-prime etc.
My question is, how could this have happened? The masking tape is not particularly high tack and this is the same method i had used on my first rubies with no probs.
Any one any ideas/tips
Cheers

As it's so cold at the moment, the paint may not have properly cured.

Also, what sort of making tape are you using? I find Scotch 3M blue painters tape to be the best stuff to use (its available at B&Q).

Cheers, the mask has been in my little workshop room which gets warm. I can only think that i did not sand the mask enough or apply enough coats of primer etc. That tape you mentioned, is it designed for going round curves etc?

You have to cut it to shape round the curves.

There are a few factors to take into consideration. Obviously you just eliminated room temp.

1. Sanding. If you did not completely sand the area then the primer willl not stick.
2. Blue 3M masking tape is good, but so is automotive pinstriping.
3. Or you can just dry brush the black areas, then clear coat over it.
My 2 cents
