How Do I Mask This

Post by TD1701 »

Hey Everybody!

I am looking for the best solution to mask the lower sensor dome for the TOS Enterprise. I have this aftermarket part for the 18" Enterprise, and I want to mask the dome to paint the ring only so I can light it. Any suggestions would be greatly appreciated! I've attached a picture of the part in question.

Thanks,

Tom

I would try a liquid masking film, or Silly Putty (trimmed to shape with a hobby knife).

I can't click the link because I'm at work and Photobucket is blocked, but I can imagine what you want to do. I'll tell you that Tamiya has recently came out with a new masking tape intended for curved surfaces. I recently used it to mask around the shuttle bay door on my PL 1:1000 Enterprise Refit and it worked like a charm! It may take a while before you start seeing it in hobby stores outside of Japan, but I'm sure you can order some online.

Silly putty or Parafilm-M from TAG Team Hobbies.

If you don't like the way the Parafilm works out, you can try frisket film (art
supply stores will carry it). I've also used Bare Metal Foil for complex masking
but it can be a little tricky on curved surfaces.

BMF would be my next pick. Tamiya tape will work but there's a greater chance for paint leaking under because of the wrinkles it'd have.

Just make sure to trim the Parafilm with a new blade.

My results were not so good. It seems that every time I try and peel the parafilm off after painting the paint chips off as well. It's as if the paint doesn't want to stick to the resin.:( I've tried it twice with the same result. I did use a brand new blade so I would get the cleanest cut. I'm tempted to just put on the AMT part and be done with it.

By 'paint' do you mean paint or primer?
If you used paint try priming first. If you used primer, which primer did you use? Did you wash the part off first? (possible mould release residue is preventing adherence.)
I must not fear. Fear is the mind killer. Fear is the little-death that brings total obliteration.

Resin typically needs primed but it depends on the resin & the primer. It's also best, with more masking, to pull the mask before the paint has fully cured.

I did wash the parts and I meant primer instead of paint, sorry about that. I tried both Tamaya gray primer, and Krylon gray primer. I've masked it a third time now, and will spray it tomorrow with Testors primer. I'm not ready to quit yet, I'm going to make this work somehow.

I'm sorry to say my last attempt with parafilm did not work out. The film turned into a goo, and the paint always seems to chip away from the ring around the dome. I'm posting a picture of how my last attempt worked out. I may try liquid mask next, and I'm not sure about using BMF or Silly Putty. I've stripped the paint off, and I am back to square one.
