David Hingtgen Posted October 8, 2003 Share Posted October 8, 2003 Iowa (the state) warmed up this week, so I can continue working on Iowa (the ship). As the camoflage on the hull is done, but the hull bottom isn't, I am taking every possible precaution is masking off the camoflage pattern. Anyways, I've got it masked, and have sprayed on a heavy, thick coat of "dull cote" (Testor's lacquer). However, I'm wondering if the gloss clear would be better to seal the tape? Or would that possibly mess up the color(s) to go over the clear? (Flat black and flat brown primer). Never tried spraying flat black over clear gloss. Anyone have experience with using various clear-coats to seal masking tape? Quote Link to comment Share on other sites More sharing options...
Mechmaster Posted October 10, 2003 Share Posted October 10, 2003 I've never used Testors products but generally matt varnishes are just gloss varnishes with a very fine powder added to give the flat finish. I would expect the gloss to work better as a sealant as the "impurity" of the matt varnishes tends to make them less robust. I normally apply a gloss coat over the whole model before applying decals since they adhere better to the smoother surface, then another gloss coat to seal the decals and finally a matt coat over the top to provide the dull finish.

David Hingtgen Posted October 10, 2003 Author Share Posted October 10, 2003 Well, I've found out that while gloss is a good sealer, it's horrendous for paint adhesion. The flat black is literally flaking off. Will have to repaint the waterline entirely. (Will re-do after the red is done). Quote Link to comment Share on other sites More sharing options...
Mechmaster Posted October 11, 2003 Share Posted October 11, 2003 Flaking off? That is strange, must be a property of the paint, as I say I've never used that brand. I mainly use Tamiya acrylics, Humbrol enamels and acrylics and occassionaly the Games workshop acrylics and while gloss finishes are certainly harder to cover when painting with a brush, I've never had any problems when spraying and I've never known paint to peel when applied over gloss finishes. I hope you're able to sort it out ok. Quote Link to comment Share on other sites More sharing options...
mslz22 Posted October 11, 2003 Share Posted October 11, 2003 i know this may be a day later and $ short but what I usually do is seal the tape with krylon crystal clear, just enough on the edge, then a mist coat of the matt finish. Just check paint compatability Quote Link to comment Share on other sites More sharing options...
wm cheng Posted October 11, 2003 Share Posted October 11, 2003 Smooth glossy finishes are definitely better for masking. The tape sticks better and peels off better. I find that the matte or flat paint has so many tiny microscopic pours that the tape doesn't seem to stick as well and that there is more opportunity for the paint to seep in under the edge softening up the masked line. If I understand what you mean by a good sealer. Quote Link to comment Share on other sites More sharing options...
David Hingtgen Posted October 11, 2003 Author Share Posted October 11, 2003 More like, if you've already masked it, and want to seal the edges of the tape, what should you spray over it? Might try the krylon crystal clear. Other question: what's the absolute "best adhering" stuff there is? I need something that'll stick to my "repels everything" gloss clear... Krylon primer? Some sort of clear? Tamiya something? Quote Link to comment Share on other sites More sharing options...
