LaurieS Posted March 24, 2021 Share Posted March 24, 2021 The little Islander I am building does not come with & no one produces paper masks. Have to use masking fluid. It is for 1/72 with lots of curves so impossible, for me, to mask up with tape. I have Mr Hobby Masking Sol. How do you apply this stuff. Mr Hobby comes with a large brush which I do believe is going to be difficult to be accurate in applying. Have one or two ideas but yours I would be grateful to hear.

Nocoolname Posted March 24, 2021 Share Posted March 24, 2021 Hi Laurie Without seeing a picture I'd be making a bit of a guess but for gradually curving lines I've used a narrow strip of masking tape - around 1-2mm width - which can still bend with the curve, then used a spare paint brush to carefully paint masking fluid over the edge that touches on the part you want covered then just add more over the open space. I've used the above approach for achieving straight lines over curved surfaces on such things as drop tanks and under wing pods as well as larger surface areas. 2 Link to comment Share on other sites More sharing options...
dnl42 Posted March 24, 2021 Share Posted March 24, 2021 I also use thin tape to mark the outline and fill in with masking fluid. Be very careful to check paint compatibility with the masking fluid!! 1 Link to comment Share on other sites More sharing options...

OP - Tamiya do produce extra narrow tape specifically for this purpose but I get much better results from cutting their regular tape into thin strips and using that.

Space Ranger Posted March 24, 2021 Share Posted March 24, 2021 Aizu also makes some narrow masking tapes in various widths. 1 Link to comment Share on other sites More sharing options...
bmwh548 Posted March 24, 2021 Share Posted March 24, 2021 I haven't used the normal one, but the R version I have grips like crazy so be careful you don't pull the paint off trying to peel it. Also: the longer it stays on the better it grips. 1 Link to comment Share on other sites More sharing options...

dogsbody Posted March 25, 2021 Share Posted March 25, 2021 I have a fairly old bottle of this: I never used it before until last summer, when I was painting my Hurricane. I shook and stirred it up as best I could and it seemed okay. I was using AML masks for the main camo, but needed a bit for the nose. When I removed the masks and the masking fluid, I saw that the Masking Sol had taken the bit of shine from the G-S Dark Earth H-72.

Chris Think Chris it sticks so well I would only use it on gloss clear plastic. I do not use Klear on my plastic but wonder if it takes that off as well.

dnl42 Posted March 25, 2021 Share Posted March 25, 2021 I've had good results with MSI Micro Mask on Mr Color paint. I use Deluxe Materials' Looks Like Glass after the canopy frames are masked and painted; the other order was a complete failure. 1 Link to comment Share on other sites More sharing options...

Mr Hobby comes with a large brush which I do believe is going to be difficult to be accurate in applying. Have one or two ideas but yours I would be grateful to hear. Hi Laurie, To specifically answer your question on the Mr Hobby product. I use it regularly as a gap filler between tape masking on canopies. My usual masking approach as described by @dnl42. This works well as I model in 1/48. A bit more of a challenge in 1/72. Typical of these types of masking products, Mr Hobby Masking Sol rapidly cures on the brush so you need to keep the brush wet in the solution. For that reason I will often apply using a smaller brush or a disposable microbrush. It is always a pain cleaning the brush as you invariably end up with rubberised hairs. I remove the residual on the brush with Mr Tool Cleaner. I do not find Masking Sol good for fine work and if you want to apply a film and cut with a sharp scalpel there are better products. Cutting to the chase, as a canopy framing product - not recommended. As a fill-in - easy and convenient. I am also not keen on using Masking Sol as a general masking product being wary of paint reaction unless the base is a lacquer. Mind you, it is very satisfying removing all the cured rubberised goo which invariably dries in the lid and in the top of the bottle. For micro masking, that is where I want to use a brush, I use the Windsor & Newton Art Masking Liquid - much thinner and easy to apply with the same curing on the brush challenge. Take care though, it smells a little like it is ammonia based so be sure to test before hand. I used the W&N product here over the decals to provide a hand painted edge to the roundels before the white stripes. The decals were sprayed with Gunze GX100 Clear lacquer, allowed to thoroughly dry, before applying the masking solution. Removal? Roll with your thumb and tap with Blu-Tac. In all cases I never leave masking solutions in place for very long. For complex small canopy framing, I am a little old school, and use burnished Bare Metal foil. Cut by rolling a new curved scalpel blade against the framing edge. Wonderfully described by Paul Budzik here. I also have made my own foil using low tack adhesive and cheaper aluminium foil, but as I always have some Bare Metal foil lying around and only needing a small amount, I have opted for convenience rather than cost.

I've done this too, one thing I have noticed though is that Maskol doesn't seem to get along with transparencies that have been dipped in Klear. In general Maskol is hugely useful stuff though, I use it to mask any and all gluing surfaces (from fuselage and wing edges to the tiniest bits) to avoid having to stick paint to paint. 1 Link to comment Share on other sites More sharing options...

Maskol contains ammonia (Klear's Kryptonite). I use Mr Masking Sol-R which is water based (you can dilute it if you want) and works just fine over Klear Note that there are two flavours of Mr Masking Sol - 'Neo' which uses an ammonia/latex mix and 'R' which is a water/latex mix.

It's a mistake I only made once, didn't so much remove it as turn it into a horrible sticky mess. 1 Link to comment Share on other sites More sharing options...
