mozart Posted December 28, 2015 Share Posted December 28, 2015 Oh dear Mark, I feel your pain! It happened to me once, in my case it was because my clear coat/thinner ratio was wrong.....not enough thinner. These days I mix my clear coat and test it on a scrap airframe before applying, once bitten twice shy as we say. Max mark31 1 Link to comment Share on other sites More sharing options...
Zero77 Posted December 28, 2015 Share Posted December 28, 2015 Ouch ! That's weird... What is this Tamiya clear coat? I only know the spraycan one, but as you talked about mix, i think you should be talking about an acrylic one. Never seen any acrylic do that on another acrylic. That's no fun, but i think you have to paint it again.... If the issue is only visual, you may just overpaint it. But if there is even a strange texture, you will have to strip the paint off. I know it's a poor consolation, but it's better to have this now than later with decals, details, and so on. mark31 1 Link to comment Share on other sites More sharing options...
Jasta 14 addict Posted December 28, 2015 Share Posted December 28, 2015 I have started to set a clear coat on the phantom so i can start in a few days with the decals. I have used tamiya clear with there thinner and this is the result. Hi Mark, ooh boy, a not so pleasant surprise Can you give us a clear photo of the bottle Tamiya clear coat that u used? Reason i ask you is the fact that there is a certain Tamiya clear coat that is in fact a base that is used to flatten a clear coat. I had that used to in the past without knowing that it was not clear coat and it gave the same effect like on you're model. Also, a Tamiya clear coat has the habit to show a white appearance if you put to much clear coat at once on you're model. I always thin my clear coat like milk and shoot multiple very thin layers on my model. Hopefully you can resolve this problem fast and go on with this very nice build.

OldTroll Posted December 28, 2015 Share Posted December 28, 2015 (edited) Was the humidity high when you sprayed? I have had this happen when the temp and humidity was high causing airborne water vapor to condense in the aerosol on the way to the model. I recommend trying a test respray (or brush re-coat) over a small area that went "bad" - this has sometimes worked for me.

Kagemusha Posted December 28, 2015 Share Posted December 28, 2015 That is a real pity Mark, the paint job was superb. mark31 1 Link to comment Share on other sites More sharing options...
Jasta 14 addict Posted December 28, 2015 Share Posted December 28, 2015 Thank's Mark, indeed that's the right one. The only solution i can give you is to thin the coat like milk ( you already mentioned that you did) and spray multiple very thin layers with a drying time between them of about max. five minutes. I know it's a little bit time consuming but the end result is that what count's. That's the way i always do mine models.

Zero77 Posted December 28, 2015 Share Posted December 28, 2015 Did you thin your clear coat with lacquer thinner? If so, maybe a thick wet coat (quite standard for a gloss coat before decalling) had attacked the painted surface? mark31 1 Link to comment Share on other sites More sharing options...
Phartycr0c Posted December 28, 2015 Share Posted December 28, 2015 Mark, Just a thought before you strip the whole lot back for repaint, try very lightly cutting back the affected area with some extremely fine wet and dry and plenty of water, or even rubbing it over with toothpaste and a soft cloth, you might be surprised The key to this is be gentle, hardly any pressure should be applied. At this stage you have nothing to loose. mark31 1 Link to comment Share on other sites More sharing options...
mark31 Posted December 28, 2015 Author Share Posted December 28, 2015 Thank you all for thinking for a solution. I will try to sand it away tommorow will keep you up to date. Mark Zero77 i have used the tamiya thinner Link to comment Share on other sites More sharing options...
Neo Posted December 28, 2015 Share Posted December 28, 2015 Before sanding i would spray another coat of clear, this happend to me once and respraying fixed it Link to comment Share on other sites More sharing options...
thierry laurent Posted December 28, 2015 Share Posted December 28, 2015 Hi Mark, I would try Micromesh to sand cautiously the damaged area. This technique already saved some kits. You have to be cautious and patient but this may solve this Rhino. Hope this helps. Thierry Link to comment Share on other sites More sharing options...
ghatherly Posted December 28, 2015 Share Posted December 28, 2015 I use the Tamiya Lacquer thinner to remove paint. IT is thinned out straight form the bottle and is no harm to clear, and if used with caution will not harm the plastic. The drawback is the you will have to start over with the paint job, and have to clean out the surface details if they fill with the pain you are removing. IF you do this wear rubber gloves and use a good paper town that is lint free. Messy but effective. I used this on the Bitburg Eagle I built a couple of years ago as the first paint job was just bad, and it worked out fine other than taking some time and patience. Good luck and don't beat yourself up, things happen! Gary Zero77 1 Link to comment Share on other sites More sharing options...
MGySgt0372 Posted December 28, 2015 Share Posted December 28, 2015 Mark, You might want to try the brand name "Future" (or its equivalent overseas) for your clear coats in the future. It should be available at your local grocery store in the cleaning isle. I've never, evver had a problem using it straight from the bottle in my airbrush for clear coating prior to decals. Sorry about your issue with the Tamiya product. That has to suck big time after all your time & effort! Masterguns Link to comment Share on other sites More sharing options...
