Belkits tyres eating paints on the rims, any suggestions?

Hi guys, I've built two belkits fiesta, and all the paints on the rims were eaten by the tyres. I'm currently building my third fiesta and I don't want this happen again. So any suggestions? Can I put some between the tyre and the rim as a barrier to prevent this thing? Cheers!

What paints did you use on the rims? Can you post a picture of the problem it might help to give a better answer?

I wonder if the fresh rubber is leetching something into the paint. Maybe a tougher clear on them. How long did the paint t get to dry before the rubber went on? Maybe the reaction is the paint gassing off and then reacting with the rubber?

First time I used gunze gx1 white with gunze gx100. Next time I used acrylic paint. Still have some problems with pictures but hopefully I can get it done later.

not very long but i think the paint has dried. It took a while for the reaction to happen(several weeks).

Well, the tire is eating the pure styrene as well, I realized a half a year ago! It happened with my Fiesta WRC, I bought it straight away when it got available and did a testfit with the wheels and tires. Left them as they were, I put the kit back to the shelf but 2 years later I realized what happened! I don't want to use those wheels anyway but I wrote a letter for Belkits if they knew about this problem, they asked me to send some pictures, then nothing! I don't know if they solved this issue or if anything ever happened...
Hopefully the Escort won't have this issue!

I've also seen this on my Fiesta kit. Maybe some mould release compound or something. I noticed it on the edge if every rim.
Wheels were painted with gloss enamel spray.

Some vinyl tires have been known to have a chemical reaction w/plastic. This goes back decades. Obviously kit production is new for Belkits, they'll eventually learn a better material to produce the tires.

I'd be using Bare Metal Foil on the rims to keep the tires from eating the styrene and/or paint. I'd also consider painting the inside of the tires in a good coat of flat black acrylic.

You have to cook the Tyres. Thats no joke. I read about this issue in an old modelling book. As ZoomZoom noted this problem is known for decades and our ancients ;) solved it with hot water.

Could you give us a bit more infos on cooking the tires please?

Could be. :dunno:

But that of course assumes that Belkits is using the same compounds and techniques that didn't work well 40-50 years ago. They may or may not be. One thing that has changed in the intervening decades since is that chemistry has advanced a bit. As a result, there are countless more options for a kit manufacturer to try to make tyres from. Hard to guess if an old solution would be effective here.

They're probably PVC tires with a very harsh plasticizer. In that case, it will likely destroy lacquers, enamels, styrene, decals and some acrylics.

You could try dropping the tires into boiling water for a few minutes. That may neutralize the offending chemical(s) enough to prevent damage.

I had the same problem with my peugeot 207. The car was already done for about 2 months and then I saw the problem. I think it is a chemical reaction of the tyres making them "sweat". My model was stored in a place with a little light on, so I think that heat makes the reaction. I talked to the people of belkits about the problem but they sid they did not know. Maybe it is possible to cook the tyres with some degreaser. Until now I don't have solution. The only thing I now that my model is clearly damaged due to this problem.

I email Belkits too this morning pointing a this tread here and asking if they have a solution to this, will keep you inform of any answer I got if any.....

If you guys want and if there is no answer on the question, I know them personally. So if necessary I'll contact them again. Jut let me know.

Me and few of my friends have the same problem. I asked Belkits what should I do to avoid this and never get any answer.
I have all their kits and all have the same problem (except Polo WRC which I didn't started due to very poor decal quality). Why to build another kit and see it damaged in few months?
I used acrylic automotive Spies Hecker white and Gunze TopCoat to paint the rims.

What's the problem with the decals..? I was going to buy the Polo, but if the decals are not so good I'll wait a bit to see if they sort it out...

would coating the rims in 2k urethane clear help?

this issue is interesting though, really hope belkits can provide a fix for this.

Yes I think a metal foil would work. I don't think paint on the inside of the tyres can solve this since the tyre would also react with the paint and maybe more or less mess it up.

thank you guys for helping me. So far I think a metal foil may resist the reaction of the tyres. Never tried cooking the tyres but this may also work. I once thought about replace this tyres with some after market products but thanks to the unique design of the rims, those new tyres just won't fit. I don't think Belkits could fix this problem unless they change the production site. It's a shame that a well designed kit ruined by some mistakes.

stevenoble: I will take some pictures of decals sheet in few days when having more free time. The biggest problem is that color layers don't fits properly to each other.

Hi Guys.
i'm Steven from Belkits.
I have seen this problem and got some mails for it, but i really cannot tell what is the problem and how it comes. We have several built kits here, already for years now, and all of them are without any problems. And we see several others, on modelling expositions, also without problems.
I have informed now with the factory if they would know something.
Maybe if some can put pictures here, or send them to info@belkits.be, i can transfer them to factory.
For those who have a bad Polo decal, send a mail to info@belkits.be and we will send a new good one.
For all our new kits from Belkits (starting from the escort that will be in stock in about 3 weeks, all decals are now produced by Cartograf)

Regards

Great customer service, very important as it's hard to come by these days!

BMF is the tried and tested way to avoid it, as Bob says.If you don't have any, thin kitchen foil and PVA adhesive should work just as well... If the wheel is too complex a shape to wrap with one piece, then strips 5-10mm wide laid across the wheel and overlapping will work, and then trim them at the wheel edges once the glue has dried solid...

bestest,
M.

I have just started an Escort kit,using Revell contacta and Tamiya extra thin and i am
struggling to get any parts to bond .Do Belkits use regular kit styrene or is it more like
an ABS type plastic.Anybody else had this problem?

Revell contacta was fine to cope with Belkits. We do have to wait several minutes to let it set. Now i use super glue a lot and that works well.

I am building Belkit's Polo R WRC at the moment and had the same problem with Tamiya cement. Revell Contacta and superglue worked better. I am really curious what kind of plastic Belkit is using for their kits.
Sadly my decals also had an offset and most of them are more or less useless. I contacted Belkits because of this issue but no response until now. As there are no aftermarket decals available this is quita a problem to me.
Their kits are designed really good but the strange glueing features of the plastic and the bad decal quality are a massive letdown.
