Problems with Tamiya molded parts

[Guest]

I hope I've posted this in the right place, apologies if I've not.


I have just opened the box looked at the parts and put it back away.


The kit in question is the Aston Martin DBS No 24316.


75% of the parts have strange lines in the plastic, I tried to take some pictures but the macro on my camera doesn't work,


The best way I can describe them is if you were to pour two different coloured paints next to each other you would get a line where the two colours meet, or sometimes when you get low spots on a panel it looks darker, well these are like that but I can't feel them like you would a low spot.


Also on the main body shell as well as these lines there are 4 areas of sharp edged raised plastic, again to describe these I would say if you were to paint too thick along some masking tape there would be a ridge in the paint when you remove the tape,


I'm not too worried about those ones because they will sand out easily enough, the others though I'm concerned will affect the paint finish, I was going to use Alclsd 2 Candy base and top coat but as these are supposed to be painted directly to clean bare plastic I'm worried all these marks will have an effect on the paint.


Has anyone had any problems like this before? and any suggestions on how I should deal with it?


Thanks,

This doesn't sound like Tamiya, and makes me think that it is a rogue kit, in which case, send/take it back and demand satisfaction. I am only a noob myself, but every Tamiya model I've bought has been exemplary - even the old ones. Plus, I'm sure folks here will give you advice on a primer for that paint you mention! Fear not!

I'd be agreeing with John ......... Take it back to the shop and get a replacement.

Thanks for the replies so far,


Having watched the video suggested by John I Am it seems the sandable ones on the front wings and rear quarter panels are the norm with this kit but the video lighting wasn't good enough to see if his kit had the other problem.


As for sending it back I've had it a couple of months under my desk and it was an ebay purchase so nothing I can really do now.


If I was painting it with "normal" paint with a primer I don't think there would be an issue, has anyone used Alclad 2's Candy base and colour coat with a primer? and what would be the best primer to use? I usually use Vallejo paints and primers but as most of you probably know Vallejo surface primer doesn't have the best adhesion.

Without pictures it sounds to me as it's just a poor mix of the plastic in the mold and if there's no cracks or bubbles in the plastic it should have NO effect on the painting what so ever

I have nearly finished a tamiya Subaru, The colour issue was the same, its no big deal because you would not complete the model without painting all the pieces anyway. The plastic finish and colour is nothing like as good as paint, its not even worth considering leaving it as is so I would not worry about this at all.

[Guest]

The reason I'm worried about the paint I'm using is because on the Alclad web site it says to spray the candy base onto clean bare plastic and to ensure there are no finger marks because they will show through the finished paint.


As I said if I was using a normal paint I wouldn't be concerned because it would be primed any way...

Thanks John, looks like there are some on the body, look towards the back of the roof there is a diagonal line running almost full width, I have the same line but there is lots more all over the kit I've got...

Ok so thanks to Ade Close Enough and his PM's I'm happy with the course of action I have to take.


For those of you who would like to know he's told me to paint everything in gloss black before I paint the candy, He had the same issues with the one he did [see link above]


I've also just ordered a new camera so I will wait until it comes before I start and get some decent macro shots...

never happened to me. I build quite a bit of tamiya's 1:48 Aircraft and the parts are beautifully molded, cripsp and wonderfully detailed. It could be a kit reboxed by tamiya. If not, it must be an exceptionally old mould or a true exception

Swirls it the plastic are a production thing and have nowt to do with being an old mould or who the maker is. The swirls are most common when a new batch of granulat is poured in the machine.


Thing of it as a marble cake. It's still cake, still in one bit. It's just two colours that have been swirled together.


I doubt it will affect the finish, but as Ade told you, a nice smooth shiny black base will remove any chance.

[Guest]

I'm sure the lines in the plastic are nothing more than two slightly dissimilar coloured plastics used in the mold that haven't completely mixed. It would not normally be an issue as the recomendation would always be to paint a model no matter what the colour. I'm surprised at Alclad saying to paint on bare plastic as this is quite a common effect and nothing to worry about. As has been mentioned I would paint a normal primer to check for surface blemishes then, when perfect a black gloss coat before the Alclad top coat.


It doesn't sound to me like there is anything wrong with the kit.

Agree entirely. There is nothing to worry about. I've had many kits with the marbling effect in them, from many brands. Prime over it and you'll see it has no effect on the surface whatsoever. Then carry on as normal.
