Revell change their friggin plastic???!!
I rarely rant. But I am frustrated with the new C6 kit. Don`t get me wrong. The details are excellent, everything is in scale, and each part is very convincing. But, I decided to paint it today, using my normal method which I have used on hundreds of kits. I sanded the body, washed it, and then sprayed with Duplicolor primer. At this point, the primer started crinkling up, and started looking like it was eating into the plastic. I tried another can of primer, a different color, and the same thing happened. So I wait for it to dry, and sand it smooth. I then spray it with the Duplicolor Black spray that I just used on my 2002 Anniversary Camaro SS kit (from Revell). The same thing happens, even on top of the primer! What is going on here? I had no trouble with other recent kits. Did anyone else notice anything similar with a newer Revell kit?

Re: Revell change their friggin plastic???!!
i really doubt it is the plastic for the following reasons:
- if the same thing happened to the paint over the primer then i don't see how the plastic could have affected this - other people don't have this problem, not that i know of(no offense) i guess maybe there is something on the plastic(possibly soap?) that is having a bad reaction with the paint. or maybe you are having bad spraying conditions that you don't know of. i know one day i tried spraying, it didn't really feel humid(but i guess it was) and my paint came out flat-ish. hope you can fix this problem.

The C6 contains 5 main parts that are body color: The body, roof, hood, and 2 mirrors. All of them have reacted the same way. The convertible top from the C5 has no issues. Quote:

Re: Revell change their friggin plastic???!!
but i still don't see how changing their plastic would affect this... this is a very strange problem, expecially because the colored coats crinkled, too. do you have pictures?

Yeah....strange, and a little . I`ll try to get some good pictures. I sure hope I am wrong. I`d hate to resort exclusively to Tamiya or Testors laquers. |

Re: Revell change their friggin plastic???!!
Well, they must have changed the property of plastic then. With increasing crude oil price, there's no reason not to if it's economically sound to the company. Bandai has just started thinning the sprues.

Re: Revell change their friggin plastic???!!
I had the same problem on the C6 with Krylon primer, but after sanding and a second coat it was a lot smoother. The plastic is obviously a different compound though, I noticed that on the seats when I tried to cut it off the sprue and ended up skinning part of it (pulled a strip of plastic right off the surface like it had a bad sunburn) The plastic on this kit is much more brittle. However, I painted two coats of primer, one mist of automotive paint, and one wet (this stuff is thick) and it didn't have any more bad reactions as of 6 hours later.

Re: Revell change their friggin plastic???!!
i had the exact same problem using duplicolor...and any other color that i laid over the plastic. it all gained a "textured" look. even when i used my color place aluminum. i left everything as it was except the body, i painted as i normally would. and when i had 2-3 coats of black on the body, i started sanding with 1500 grit until the surface was even. then i laid another coat of black, and followed with 2-3 coats of clear. i then followed the same process with the sand paper, then hit it with a couple of passes with my 3m rubbing compound, then a pass with my kit scratch remover, and then meguiars gold class wax...you should be seeing a completed thread on this one pretty soon

Re: Revell change their friggin plastic???!!
I didn't see the problem repeat itself on the new SRT-10 Viper model, it may just be the C6.......I hope.........

Re: Revell change their friggin plastic???!!
i was thinking some water soaked into the plastic and got to the primer because this happened with that 1 persons s15 with the lambo doors.

The kits are produced in China, I'll get back to that.
I first noticed in (a Revell-Monogram kit) what you described when I built an Acura Integra. (Seen it in many other models from several other manufacturers too.) Even Testors enamel paint (airbrushed) ate at the plastic for the interior as if it was a hot lacquer based paint. Anywhere the surface of the part was disturbed by trimming sprue or flash, or just sanding, created a very unstable area. I noticed years ago, models I worked with that were produced in China, had a softer styrene than we are used to seeing. It's a different formula, and as such, reacts to paints and cements differently. The worst part is there is no uniformity from kit to kit. I've had what seems to be the same plastic from the same manufacturer react differently at different times. It's something we have to live with if we want new models produced. The remedy is simple. Take each model on it's own merits, just because you were able to do something before, does not mean it will work again, the compound may have changed. Make sure the first couple coats of paint/primer are thin, light and somewhat dry. Don't flood the paint on after you have built up a "barrier" coat either. Basically follow the guidelines of how to paint well. You just can't get away with a few of the painting shortcuts like we used to. Tamiya Acrylics do not seem to react with the plastic at all. I have had pretty good luck with Tamiya TS sprays and Tamiya primer as a barrier on that type of plastic. Once you get a nice finish, and it lasts for 24 hours, you're set. If it crazes, let it dry. You can either put a couple more thin coats of primer on and sand smooth with very fine wet paper, or if the crazing is light, just sand and repaint. I have had more uniform results by building up a thin primer barrier and wet sanding (if needed) before painting when the problem manifests itself. Good luck... - Mark |
