How do you achieve your gloss coat (products, methods and drying times)?
Posted by ohms on Tuesday, April 12, 2022 3:43 AM

Hi everyone,

 

I asked a question about gloss coat methods on the 'general discussion' page. Was advised to ask my question here.

 

If this has been answered before, I'd appreciate links to those discussions, that way saving people from having to type out the same thing again. Pics are also most welcome.

 

If you guys didn't see it, below is the original post:

Hi everyone,

 

I noticed that there are many different methods on YouTube on how to achieve a gloss (mirror) finish. I was wondering if anyone wanted to share theirs. Do you thin your gloss? Do you use urethane? What sandpaper grits do you use after applying the coats? Wet or dry? How long do you wait between each coat?

 

I'm guessing I'm asking for a lot of typing, but I'd really appreciate any and all feedback. Want to try several methods through R&D.

 

Thanks.

hey, folks, lets help this guy.  I have already given him some suggestions.  I have seen many threads on this issue in the recent past.  Maybe folks have gotten tired of discussing it, but how about helping a new guy to this forum.

Hi missleman2000.

 

Thanks, you're awesome.

 

But don't sweat it. I do have YouTube videos I can refer to, and trial and error of course. I won't hold it against the guys for not wanting to discuss the same thing ad infinitum.

 

Just seeing if anyone wants to provide me with extra detail. YouTube may show things like mixing ratios, but they don't tell you about drying times. 

 

I'm going to try 2k urethane made for automobiles in a few days. I've heard it's a lot more foolproof, but ventilation is a necessity.

 

If no one replies to this thread, it's all good. I've been a fan of the forums for a while and will continue to feel a part of the community regardless.

Notes I got from BrandonK on using 2k

 

I used my .5 needle AB, 4 parts clear, 1 part activator, straight through, no issues. 

Just gear up and don't breath this stuff or get it on your skin. 

20 psi was more than enough.

Thanks,

John

For gppd gloss I generally use a pretty low pressure, 12-15 psi.

1. Yes I thin it. Most times a 50/50 mix. But that is not a hard and fast rule. Depends on what you are using. Some clears might not need any, or very little.

2. If you are really good, and REALLY lucky, you might be able to apply a beautiful gloss without sanding. It requires working the paint, drawing out the gloss in a heavier application. You have to be lucky because invariably, something will land on the model. Whether it be dust or sometimes bits within your paint mixture. Not to mention, paint buildup on the tip. It's a rare thing to get a perfect finish. This is where note 3 comes in.

3. Get a polishing kit. It takes the guesswork out of the process. I believe these kits come with instructions and it gives you all that you need to know. I am just getting back into car models and I will be using one as well. If you follow the process it fixes most any blemish and it gives you an incredible shine. Link below. There may be other kits available, you'd have to search it out.

4. 2K has been mentioned. As Keavdog noted, take precautions if you use it. It is not something to be trifled with. I can't stress that enough. Do your research before using it.

I usually use Novus2 to polish to a mirror gloss. I did my F102, 106 and Blue Angel F18s with Novus and got excellent results.

I agree, Novus2 is my go to product for getting a mirror gloss.
