Hi Guys,

Sometime after I sprayed Gunze Flat Clear Base on the painted model kits, the flat base will turn white. I would like to know how you guys do to prevent the flat base from turning white.

I am not sure if it is the same as with Gunze, but Tamiya's flat clear base is meant to be mixed with the paint when applying it to the model. If you just spray it onto the model, it'll turn white. Perhaps this is the same type of situation?

Steve, happened to me in my first model too, I think something to do with the paint not fully dried or while spray the flat the room is too humid....

If your talking about Gunze's Super Clear Flat in spray can, yeah I too have that problem. I initially thought it was because the one I had was old stock. In another forum, I was told that it was the humidity. Made sense since I live in a tropical country. But I remember using the flat coat when the weather was perfect (i.e. not high humidity) and I still get that white 'fog'. Possible reasons: 1) the can wasn't shaken as much as it should be, or 2) too much of the clear coat (either too many passes or too close to the model). Anyway, whenever it happens to me, all I do is dip a cotton bud in Gunze's Mr. Thinner (lacquer), and carefully gently lightly roll the cotton swab on the offending white portion. A little bit of the flat coat remains on the model - enough to protect the paint work and give it a flat finish.

Hi Guys,

Thanks for all your suggestions to prevent the flat base from turning white. And GIBeregovoy, I will try your method to see if it works on my kits.

I learned a long time ago to ALWAYS test flat coat on something before you spray your model!!!!
I use a glossy magazine picture........wait a couple of minutes.......if it's flat and not white.....then spray your masterpiece. This will take care of your problems too...mixing could also be your problem too......aerosol cans have to be shaken for a good couple of minutes before spraying....but always check it on something before you spray your model....ALWAYS!!!

I just did a quick yahoo search.......If Gunze Flat Clear Base is H40 then
Mixing one drop of Flat Base (H40) into a color cup of a gloss color will make it dry flat.

It's not a "clearcoat" It's Tamiya all over again

My suggestion... stick to ModelMaster Flat Matt Spray #1960. Never let's me down!

Thanks again for all your help.
I have read some tech guide on Tamiya USA web site and learned that if you want to have better result while with spray can, you'd better heat up the Spray can a bit and shake well before spray it to your kits.

I remember reading that in an FSM article on enamel paints. It said, when using enamel paints in spray cans, always warm it up by filling up a basin with warm water, then putting the can in it (water level around a third or half the height of the can). It will make the paint inside flow better.
