Zippi Posted March 18, 2021 Posted March 18, 2021 I have some Dawn Power Dissolver on hand. Anyone ever use this? I don't want to take the chance of screwing my parts up?
Bainford Posted March 18, 2021 Posted March 18, 2021 I have not used it myself. It may or may not remove chrome, but pretty sure it will not screw up your parts, so ok to have a go. Other chrome strippers include bleach, Castrol Super Clean, Easy-off HD oven cleaner (NOT the fresh scent stuff). There are other chrome removers as well. Many products will remove the shiny chrome, but the clear lacquer undercoat is more difficult to remove. It is not necessary to remove the undercoat if all you want to do is paint the part. However, the undercoat can obliterate a lot of fine, molded detail on the parts. It is often desirable to remove the undercoat in order to restore this detail. Fresh Castrol Super Clean is sometimes successful at removing this undercoat, though I have had better luck with brake fluid. Brake fluid can be messy to work with, though. Perhaps 91% or 99% isopropyl alcohol with remove the undercoat, too. I have not tried it, but it does work well at stripping lacquers.
Zippi Posted March 18, 2021 Author Posted March 18, 2021 Bainford, Thanks for the info. Yup....I just wanted to prime and paint. Wasn't sure if the paint would stick to the chrome.

If you just want to remove the shiny chrome part, about 5-10 minutes in common household ammonia does the job. So fast you can almost watch it happen.
Rodent Posted March 18, 2021 Posted March 18, 2021 Just look at AMT or MPC chrome wrong and it comes off. Revell chrome (in my experience anyway) has a much tougher undercoat layer to remove. You will probably need one of the stronger strippers like the Easy-Off for that.

There are many different types of model "chrome" out there and each seems to need it's own chemical to take it off. Often that is because there may be three layers or more of different coatings. Sodium Hydroxide(super clean and oven cleaner) will take most of them off, but sometimes you have to go through a series of strips with NcOH and alcohol. DOT 3 Brake fluid also may need to be thrown in the mix. NEVER COMBINE THEM IN THE SAME CONTAINER. Use them separately and rinse them thoroughly. Also get a good pair of rubber chemical gloves to protect your flesh.
Zippi Posted March 18, 2021 Author Posted March 18, 2021 Thanks for all the info fellows. Since I'm just painting it looks like I won't need to remove the chrome.

To me, it depends on what you are painting. Some of the "chrome" is really heavy and a few layers of paint over that will further obscure detail. You might be surprised at how much crisper the molded part looks without its chrome.

tim08 Posted March 19, 2021 Posted March 19, 2021 If they're small parts I just paint over. Larger parts I'll strip with oven cleaner, wash ,then paint

kurth Posted March 19, 2021 Posted March 19, 2021 Dawn power dissolver is effective at removing paint, and chrome. It seems to work like a less harsh oven cleaner. I have not seen it in stores for some time, so lucky you for finding some. It also works very well for the intended purpose of cleaning cookware.

Classicgas Posted March 20, 2021 Posted March 20, 2021 I find bleach works well for most chrome, you can usually watch it dissolve. If it's extra tough, yellow can Easy Off oven cleaner.

If it's extra tough, yellow can Easy Off oven cleaner. Bleach will not remove the glossy clear undercoat that the "chromed" parts are sprayed with before metalizing. Sometimes the clear coat is laid on fairly thickly. To fully strip the parts to bare plastic, it is important to use stripper that will handle both. Any Sodium Hudroxide (Lye) based products will work well.
Classicgas Posted March 20, 2021 Posted March 20, 2021 Thus the mentioned yellow can Easy Off Oven cleaner. Most parts i strip i really don't need the clear removed on.

I tried the Dawn Power Dissolver and didn't have any luck. I'll try the bleach method tomorrow since the wife has some on hand.

I used to love the stuff when it was commonly available.
Zippi Posted March 22, 2021 Author Posted March 22, 2021 Thanks for the tip on the bleach fellows. It worked just fine.
peteski Posted March 22, 2021 Posted March 22, 2021 It removed the metalization, but the shiny clear undercoat is still on the plastic. But maybe that was your goal.
