Contaminated Plastic?
Posted by modelcarjr on Tuesday, September 10, 2019 8:56 AM

I have sometimes wondered if certain lots of kits have contaminated plastic. Recently, I was looking for the new Revell 68 Chevelle release. There were none on the shelves at my local Hobby Lobby. I wandered back to the clearance isle, as I normally do and found two 68 Chevelles marked down to $7.49 so I scooped them up! I wondered why they would mark down a brand new kit to such a low price.

When I prepped the body for painting I paid particular attention to any flaws. Sure enough, I found a spot on the left side door below the belt line and just above the chrome strip that runs the length of the body. I sanded it out, washed the body and primered it with Bright Touch, a generic, sold by O'reilly and made by Sherwin Williams. I've used it for several years with good results.I still saw the spot in the primer so I sanded it out again and then re-primered and thought I had covered it. 

After the primer dried overnight I applied the color and clear coats the next day. Sure enough, the spot appeared again, almost a perfect circle, in the 1st color coat and even with dedicated second pass over that spot it still was there. I finished another color coat, the clear coats, and rubbed it out after it dried.  Fortunately, its not very noticeable since its below the beltline and just about the decal that has been since applied. I just wonder if the lot numbers for this kit were idetified and discounted significantly because they were identified as defective. 

There's a happy ending - still took second place in Factory Stock in the last contest! 

If you cannot have a good time, what kinda time can you have? JR

Next on the bench:  Another 1970 Hemi 'Cuda, 1958 Chevy Impala, 1987 Buick GNX, 1950 Chevy Pick-up, Indy Reynard, 1965 Corvette, probably not in this order.

At least, yours was just a small spot.  Mine was the entire body!  I can barely see where you had an issue with the plastic and its location was close to be completely cover by decals.  Good job Jr!

I recently had an issue with contaminated plastic as well, on a new Revell kit.  In my case it was a soft gooey spot.  I don't know if entire lots of kits are tagged as you suggest, I suppose it could happen, but think in your case they just cycled older stock to make room for newer items and you got one with a defect.  I don't expect the issue I had to be a common one either.

 See, all you model car builders out there. I wasn't seeing things! I recently purchased another Johan Oldsmobile Starfire kit. Like my other unbuilt one I acquired some years back it had a problem.

 The plastic had measles! Yup, white body with, this time little red speckles in it. This is not the first time I have run across less than perfect plastic moldings. Lindberg and Lifelike use to be bad about short shots.( Incompletely formed parts) or burned plastic.

      I have had few problems with Short Shotting with most model cars. I have had some small problems with heavy Flash from a mold that doesn't close completely though.
