question about dupicolor color match

[martinfan5]

Is dupicolor color match paint safe on plastic?, I am asking this because I pick up a can today and it ruined one body, and a test hood. I used dupicolor primer .

I am not sure how to explain what happened but I think crazing or etching maybe is the term.

And I have one more question, before I bought the dupicolor, I tried MM black enamel, is MM enamel the same that's is in the testor cans?, I was not happy with it .

I've used the Duplicolor Perfect Match, and with every color so far it came out fine if sprayed properly. I use it over Rustoleum gray primer, which I let cure for a few days before painting with the Duplicolor. With this paint, make sure you spray it in several light mist coats to let the color build up, don't put on a single heavy coat. Also, this paint needs a clear coat to really shine, without it, it appears dull or semi gloss. Are you spraying the model from about 10 inches away? Doing it too close (or spraying too much on at one time) can make the paint build up quickly and it won't dry properly, causing some spots to appear cloudy or hazed. The weather you're painting in can make a difference too, if it is too cold or too hot it will affect how the paint cures on the plastic. If you can, make yourself a ventilated indoor painting booth, too much humidity can cause paint to craze too. Personally I have the best results when the temp is between 65 and 75 degrees. I hope this helps

Also, with any hotter type of paint, lay down a layer of Future before hitting it with the color. Future acts as a barrier to help protect the underlying plastic.

As a side note, I was also told (by someone who most certainly knows far better than I do, that Future can be used as a barrier if you have done any body work that involved body-filler. most paints like Dupli-color will 'Ghost' your body work lines when shot, even if you can't see it in your primer coats. Do your body work, shoot a thin layer of Future, then apply your primers once the Future is dry (this is how it was explained to me).

I did several mist coats and then a few wet coats, but it etch the entire body

Too much at once....I shoot duplacolor and HOK without future,,,just duplicolor primer

I've used Duplicolor on 9 or 10 kits and haven't had a problem.

I use Duplicolor all the time after priming with Duplicolor primer first and no Future. But I did have a problem one time with a Revell kit. There was a period of time when Revell's plastic was known to be more sensetive to automotive paints but Revell addressed the problem. If that's the case, then Future could be used to seal the plastic before painting.

I just tried priming an amt body, and the dupicolor primer etched the body as well, I have not been having problems using dupicolor primers up in tell the last few times. I just used it on a revell kit without any problems, but when used on an old mpc kit and now an amt kit, Its etching the plastic.

But here is the funny thing, I used the same primer a few days ago on another amt kit, and the primer did not etched the plastic, so now I am a little confused.

I will from now on start using future before I prime and paint

Could have a bad mix in the paint? Just a theory I wanted to add.

[prostockmania]

Are you using the right duplicolor primer, and were all the cars spayed out of the same can?? They have an etching primer, so it may have been a mix-up, and mislabeled.

I have used duplicolor high build sandable primer on hundreds of bodies, and never had a problem.

Best duplicolor primer is the one label, "Primer and sealer". Comes in a gray can. Shoot light coats first, sand and then apply wetter coats. Just shake it for about 3 minutes before spraying.

[shucky]

Agree with Mike above. I've used this primer as well as DC spray cans w/out any issues ever. No sealer, nothing fancy needed.

[martinfan5]

This is the first time I have had any issues with dupicolor primer, I have been using it for awhile, I am using the grey primer sealer and white sandable primer, and its happening so far with both . I know the know its not miss label, as I have been using the same cans for the last month or so.

[Erik Smith]

The gray primer sealer will etch - I have found it is "hotter" than the sandable primer. It (sealer) isn't really necessary with duplicolor primers.

Being in Europe, I'm naturally used to Dupli Color. It definitely is slightly more aggressive than other automotive spray paints I have used and I do not recommend using it on old annuals.

Also, IMO Dupli Color primer should be avoided altogether, unless you follow the advice of the people who have replied to this thread already. They seem to have mastered what I failed at.

I use an automotive primer made by Holts (not sure whether it is sold in the US, it's a division of Sonax) and find it much less agressive than Duco. As has been said before, it needs to cure for several days until you can shoot Duco paint, and if you do, start with really thin layers, i.e. just fogging, until you have the model completely coated. Again, let it cure for several days. Then carefully wet sand and shoot your final layer. The fogged on layers from a few days back act like a barrier.

But...

Dupli Color works a treat on resin kits! If sprayed on hot enough, you can achieve a fairy tale gloss with it.

This is what I find odd, is that I sprayed the primer on two different AMT kits , and it etched one but not the other, and both kits have been issued with in the last few years.

Thanks for help guys, its a little frustrating trying to find paint/primer that works, and when you do find one and go awhile with out problems then the problems start

[my80malibu]

I have used the Duplicolor scratch filling primer with no trouble at all. I prefer Plasticote t=235 primer but only a few auto parts stores have it and it's a far drive to get just that.

[moparfarmer]

Can't buy Plasticote T235 or any Plasticote here in Winnipeg Canada. Been using Duplicolor sandable primer and it works good. Canadian Tire who sells Duplicolor have a new can out. Its thicker and not quite as tall, seems to be not as hot, kinda like an acrylic/lacquer. Goes on smooth and polishes up real nice after clear coat. Just my 2 cents worth.

[Sam Cates]

Maybe I am missing something here, are you washing your parts with soap and warm water? I have had that problem with Krylon before, it seems to me that it depends on how long you wait between coats, and I always clean and sand between each coat to remove any contaminants that may be present between coats.
