Liquid Mask

[Jerry Matoon]

OK i am new to this stuff for painting lexan bodies so forgive this crazy question. Can you brush this stuff onto the lexan body if certain parts of it have been painted already? Such as the windsheild and door window frames and handles. And will it stick and not bleed through in these areas?

Thanks for any help

not sure that I understand what you are trying do do here. You have a painted area you want to mask off? is that right? On a lexan shell you don't need to mask an area already painted.

If you could explain a little better what you want to accomplish, I can probably give you a better answer. I've used it some.

its not a simple paint scheme i am working on; I know i dont have to mask off a painted area; but lets say that some of the mask hits these areas; all i want to know is if the liquid mask will attack the paint and possibly ruin what i have already painted or should i paint some scrap and see what happens?.

OK i came up with an example. These lightning bolts that are popular. Say you paint the white and then highlight it. Now you (or I) want to mask the body completely in order to paint a couple other designs in the same area as the lightning. would the liquid mask adhere in these painted areas; not allowing bleed through and peel up as a sharp cut line when i cut the design out? And hopefully not attacking the paint that is already there.

Ok I gotcha now. Not a 100% sure on how it will reach but I think it would be safe. But I'd test on scrap firt to be sure.

thanks for the help and your honesty. Do you have a preference on what kind to use? Parma, Hobbico, etc?

Ive used parma with a good outcome. I never used it on large areas. Just small details here and there that would be pain to tape off.

You can brush it on or spray it.
I use Bob Dively mask.

I spray or brush the whole body.
Then cut out whatever design.
Peel off what you want to paint.

Make sure you apply it very thick, or as to say many coats.

This stuff is a huge pain to remove if it's not thick.

You also need a "New" razor blade to cut it so it does not pull off the lexan.

You should not have to go back, and apply it over a design, if you spray the whold body to begin with.

But it should not stick to lacquer paint.
But it is water based, and if you are using water based paints,
it may soften the paint until the mask dries,
Not sure after that if it will try to bond to the paint.

I use it for the windows, and all as it can be "fit" better than the mask kit that comes with the bodies..

Umm, that is a tricky question. When using the masking, I Use PARMA on all my jobs. Placing it over a painted are that hasnt been finished off with a protector spray to seal the paint on will peel right back off the body woth the masking. Yo may want to use carefully placed blue masking tape around the area you are painting and work that way. But I wouldnt suggest masking over a prepainted are that isnt sealed. Unless it is acrylic paints. which cry harder. The only othe problem you would have doing this is even if your area that was painted was sealed. The surface should had benn prepared correctly. if you just painted onto a unprepared surface. you will also pull up the paint.

Nah; i always prep my bodies before i paint them; never had an issue with any paints peeling up/flaking off; or not sticking due to mold release agents or oil from my hands.

Thanks for the info
