Default Restoring finish due to rub marks

Have an F-14 model with a matt finish that arrived with some rub marks(shiny). ..Small ones, but noticable in the light... I suspect this occurred in transit when model rubbed against its plastic blister.
Anyone have a technique for fixing these types of blemishes, other than painting over them?

if its a mark on a matt finish unfortunately its very hard to get rid of it, because a matt surface is actually rough on a very very small scale, meaning the light is scattered. Effectively what has probably happened here is that the plastic (or whatever rubbed it) has smoothed out and destroyed that rough matt finish, making it shiny, so its effectively impossible to restore it back to a rough surface without painting it.

In fact even if you painted over it with matt coat it might still show, so you probably would have to lightly smooth the entire surface before painting (preferably with an airbrush) to get a truly uniform effect. I would say ignore it, its the best (only) thing you can do without risking the model.

All the best

I guess you're right, Jamenator, best to leave it alone than to risk messing up the entire matte finish. I'll just display it in indirect light!

Maybe a very light brushing of Testors Dullcote..?? I've never had this issue to try some Dullcote on, but it might be worth a try, maybe someone here that has experience with Dullcote can chime in on this.

Thats possible, however be careful as i believe thats a lacquer, so it may attack the paint underneath. Personally I would never paint a diecast unless it was already dead to me, but if I did I would use acrylic such as Tamiya acrylic flat clear as they seem to be 'gentle' and dont harm most kinds of paints

I'd simply take a paper towel, cut out a hole slightly larger than the affected area, then, using the towel as a mask, place it over the model so only the marred area and immediate surroundings are visible. Make sure that the canopy, in particular, is covered. Then, a quick angled spray with Dullcoat, at about eight inches from the surface ---but not directly from above---should do the trick. There is no problem using Dullcoat on diecast models. The trick is to apply it lightly, then see if you have the uniform matte finish you desire. If not, repeat the process. If you spray the entire surface---say a wing---where the rub mark was evident--that wing will appear duller than the rest of the model. Fixing a much smaller portion of the wing makes this much less evident. Remember, spray the DullCoat at an angle from about eight inches---not directly from above. Use a quick back and forth motion.

Good luck.

Wink Re: Restoring finish due to rub marks

I would agree 100% with Mr. Epap, as I've done this several times with complete success. It is critical that the canopy and ANY OTHER clear parts be masked/covered. The key to success is patience, and thinking the process out in your head first.

Testors Dullcote works fine, or you could also use Tamiya Matte Spray. I use the latter as it is what is available to me.

Good luck!

Clean the surface of the plane first (canned air and even isopropyl alcohol if necessary). Warm up the spray can before you use it (give it a bath in hot water) (this is absolutely essential for a good job with an aerosol can) and shake the can for at least a minute or two before spraying (and then put it back in the hot water and shake again). Spray light coats after masking off any area you don't want to be matte.

If dullcote is the answer and it were me. I would mask off the canopy and shoot the whole model and accessories for an even finish. But that's me.

I would suggest if this is your first time painting with an aerosol can, best to practice on a discarded model or a cheap model kit before doing the repair.
