This really all depends on the problem / issue. Buffing may be the best course or additional coat(s) may be the option. We do NOT have enough data to make that recommendation.
One caution to the OP: some polys, like imrom, get very hard as they cure. If you plan to buff, strongly suggest you get the manufacturers recommendation for when to do it. Some polys become very hard to buff effectively after 2-3 days, some don't. You can always scuff it and shoot another coat. However, I would not do that until you figure out what you did wrong and how to mitigate it.

Thanks to all for some great suggestions
The paint is a single, two part application. I did use two coats
I will try the sand and buff first as i think the temp might have been low as i let the garage door open to let the overspray out briefly then closed and fired up my natural gas heater when safe to bring temp up to 20 C of 71F.
Thanks again to all, sounds like we all learn something during this part of the build.
I was quoted 8 thousand Canadian to paint it so i thought i would paint myself, i have done a few things but nothing this big.

most temp recommendations are panel temp and paint temp, not air temp. So, if the garage had been at 70* for a couple of hours before you sprayed, opening the door during the spraying should be of no concern, as long as the panel temps didn't drop below the critical level (likely 60 or 65*) before the heat went on again. I have done that several times with no consequence and under the advice of the paint manufacturer.
I am guessing it may be dry spray, which should be no issue to address with cut and buff. I would see if you can get it flat enough with 1500 or whatever is required by your buffing compound. Many single stages won't allow much removal without creating a mottled appearance. They aren't like clear coat in this regard. After the cut and buff, you'll want to examine the surface with sun light then determine if it is acceptable or whether a recoat will be required. You can also top it with clear coat to make any repairs or buffing easier.

Before you do anything drastic get a local experienced painter to take a look and offer recommendations.
What brand paint are you using? Do you have all the data sheets for that system?

I'm with Sam. Get an experienced painter to look at it. There are many kinds of "dull" with different causes.

If you do decide to cut and buff I would recommend the 3M Perfect-It 3 step process. Get or borrow a good quality polisher that has a feather trigger such as the Dewalt DWP849X variable speed. And tape the edges so you don?t burn through the paint. 3M has some good tutorial vids to help. It?s pretty hard to mess up Imron if it?s fully cured. Post some pics.

Hi Dave,
Do you come to Edmonton often? I have been professionally painting airplanes for well over 30 years. I'm currently working on a F1 Rocket project and just painted my Citabria at my hangar in my spray booth. If you wanted to bring one of your painted parts to my shop, I will gladly give you some free advise. We could try to polish what you have now also. I'm not looking for extra work, because I have too much right now, I like helping fellow RV'ers.
Cheers,
Phil Kite
