Hi there,

The rims on a couple of my ut models are starting to melt (well the paint). I know that this is a common problem on a lot of there cars, but is there any way to prevent these rims from doing this or to stop it if it has already begun? Any help would be appreciated

:cheers

Strangely, of my 10 McLaren F1 GTRs (& one LM), the five spoke rims are okay. The cars with the multi-spokes do have the problem you mention. I've yet to heard any solutions to the problem. =(

The only thing that comes to mind is a clear spray sold by artist supply places that is some sort of fixative or sealer. Krylon make one as do Winsor and Newton. I've never tried it so experiment entirely at your own risk!

One of my MacF1s has the problem. If you touch the paint you can see that it's very soft (it's not peeling, but it would be very easy to peel it from the rim with your finger nail).

Unfortunately the only definitive solution is to repaint the rims. If you paint over the melting paint it will still come off.

That really bugs me and is probably one of the reasons why I don't really jump after Mac F1's. My MotorMax Chrysler Crossfire's rims had this happen too. The paint was almost to the point of dripping off!

It's the black Mercedes C36 AMG and a silver BMW Z3 roadster with the luggage rack on the back with the 5 spoke non M rims.

I have the same problems with my C36's and I just try not to touch the rims..... :shipwrecked

:iagree this problem has been discussed many times before and the only sure solution I've heard of is to strip all the paint off the rim, wash the plastic rim and the tire in something like a detergent and repaint the rim. I think the paint softening is due to a chemical reaction between the tire and the wheel (some kind of chemical on the rubber that reacted with the paint, or something like that!)

Personally I take Gunthers approach and try not to touch the rims! :cheers

I had this problem on a UT Porsche. I stripped off the bad paint, which was only peeling off where the tires met the rims. I re-painted the rims and then sealed them with clear acrylic, (water based) before I put the tires back on.

Thanks guys for your help. The cars are still in the boxes so they hardly get touched. ill try to repaint the rims.

I have six UT cars right now and still have the wheels from my old red Escort Cosworth and not one of them hs this problem.

I have..

Red E46 328i
Silver Escort Cosworth WRC Street
Yellow E36 Coupe
Silver Z3 Coupe
Red M Coupe
Blue 993 Carrera RS

Perhaps these are generally ok, or perhaps climate has something to do with it? My room is an end of terrace, so quite cool at times.

I don't think it does, it comes down more to luck really from what I've heard about the problem. I'd say my models are kept at room temp most of the time and the weather in Dublin would be a bit cooler perhaps than Plymouth and yet I have one or two UTs with this problem.

The general consensus when this problem first surfaced on various diecast message boards was that it is due to a chemical reaction between the tires and the paint on the rim. Possibly a "releasing agent" applied to the rubber tires to get them out of their molds more easily. I believe for this very reason plastic kit makers always advise you to wash the parts in a mild detergent to remove any traces of such a chemical off the parts before painting them. :cheers

Recently that is happening to my silver Mclaren as well, the paint peeled off when I was trying to remove the little tyre blister which sticked on the rim, but luckily the problem is not very serious and the rims are not chrome but normal silver, the area is small, so I believe I can manage to repaint that. And I will never try to touch the rims again.

I currently have 10 UT models in my collection, including..

996 Carrera
993 GT2
993 Turbo
993 Cabrio
993 Targa
993 nose GT1
Mac F1
F1 LM
F1 GTR UenoClinic
Ferrari 550 Maranello

So far, the only model that seemed to have an issue is the Ferrari, but I didn't realize that it had a problem until I touched the rim one day and saw a bit of the black plastic show underneath. I took a clean microfiber cloth I had laying around and swabbed off that bit of loose paint and retouched it with a silver automotive paint pen that I recently purchased, then used the clear coat on the other end and it seemed to do the trick. I never touched it to see if that helped, but I no longer see any unsightly blemishes. I don't actually touch the other models anymore, so I'm not so sure about them, but it did make me wary all of a sudden.

I knw that this thread is old, but i am having sleepless nights because my UT BMW e46 318i sedan has sticky wheels. Fortunately not anything major, but as long as i dont the touch the wheels would it be fine or are they known to get worse over time?????

I have considered two options,

1. If it gets worse Remove the paint using nail polish or something and use a automotive paint pen to repaint it and then use a paint sealer

2. Before it gets worse apply a paint sealer.

What would be the smarter thing to do? If no 2, what is a good paint sealer?

any response would be greatly helpful in enabling me to have a good sleep tonight :giggle

I was offered a UT Porsche 993 Turbo which I was hunting for sooooo long,only to find the rims had the same issue which put me off completely!

Hm, that sounds good. I have old rims, which I don´t need anymore. I will try this.
Not the rims are the problem. The tyres are the problem. They evaporate so strongly, if you have the modelcar in a showcast, like mine, the showcast bottom (black plastic) are also melting!! I saw it, so I glued a piece of felt on the bottom of every car.

It's the tyres that are making the paint melt. I've heard countless stories of paint being melted by rubber tyres on forums like Armorama and Aeroscale. If the stories on these sites are anything to go by, get the tyres that are eating the paint off the rims ASAP! If you leave them on long enough they will melt the rims themselves. The best thing to do is to strip any affected paint off the rims, repaint them, and then seal them with Future Floorwax. That should prevent the tyres from eating the paint, although it would be a good idea to take the tyres off and check for corrosion of the Future layer every year or so.
