Parma liquid mask for aircraft canopies?
Posted by mfsob on Wednesday, October 26, 2005 9:06 PM
Tackling my first airplane in about ... 40 years, a B-25 with that wicked greenhouse canopy nose. The local hobby shop does't stock Bare Metal Foil, but she handed me a bottle of something she said the R/C crowd uses - Parma International Liquid Mask, No. 701.

It's really thick, blue, lotion-looking stuff. I'm applying it to a test panel, but has anyone else ever used this stuff for 1/72 airplane canopies, or did I just blow another $4?

I've used it before. It's ok...I just don't like having to wait for it to dry, and if you screw up cutting it, you have to re-apply and let it dry...again. I also had a hard time seeing where it was going on too thin and it tended to not lift up easy, once painting was done.

I prefer Parafilm-M

Not easy to lift off? Swell ... Well, I've put three layers on my test piece, going to spray it tonight and see what happens.

It didn't lift paint, but it tended to break apart (not come off in one piece) so I had to work on it gently with a toothpick. I use acrylics so scraping on the painted surface is always treacherous.

Good Luck!

You might consider a precut mask by Meteor Productions or Eduard. I love the BlackMagic masks (Meteor's product name for their masks) and use them as often as I can. You can check out http://www.meteorprod.com/ and look under "Featured Product Lines" on the left side.

I used it to mask this camo on this 1/72 PM Horten 229. I know it's not canopies. I had problems with it sticking too well and it pulled up some paint because I was in a hurry but it's ok otherwise. I used BMF for the canopy itself. It'll probably work fine but I suggest BMF for canopies. One sheet will last a long time for 1/72 aircraft.

I've found that the Parma is not "precise" enough, at least for 1/72 aircraft canopies and noses like on my B-25 model. The stuff is so thick and gooey that it is almost impossible to keep it where you want it to go. However, I am keeping the bottle in case I ever want to do some kind of camouflage scheme, it should be just fine for that.

And I did end up using Bare Metal Foil to mask the canopy and bombadier's greenhouse - one more coat of olive drave and I get to see if it worked or not!

You do realize that, once it's dry, you can cut it with a razor to get the precision you need. Sounds like you are just trying to brush it on the parts you want to mask.)

Yep, and I did that, after brushing on three coats, waiting for each to dry, etc., like the directions said. It still came off in chunks from the areas I wanted to remain masked off. Thankfully this was on a test piece I put together, so I didn't have to scrub the goo of the canopy.

Awe man. That sucks. Like I said, I had the same experience....I'd opt for something else going forward. Bare metal sometimes leaves resedue. My favorite is Parafilm-m.
