Touch up for INTERIOR caulk filled holes

[ScottyGS]

Recently replaced our A/C with a new unit.  The Air distribution box has a smaller footprint than the old Penguin.  So, I filled in with white caulk.  Of course, the white caulk is not as white as Donna would like it to be.   

What suggestions do you have for touching up with a whiter white.   Touch up Auto paint?    These are small...  about 1/8th inch in diameter but there are eight of them.  Plus they are on the ceiling so they tend to be noticed around bedtime.   Help me get a good nights sleep... Please!

Here ya go. Cheaper than touch-up paint or new caulk, and an outdoor camping experience to boot!

I had these in my bedroom as a kid, and it was the first thing that came to mind. Not actually helpful, but they might be a distraction. 😉

Would Donna be amenable to sleeping outside? That way she wouldn't notice.

Just Kidding..........

I used white plastic hole plugs similar to below when I changed out my A/C.  I actually had to enlarge the holes to get the smallest one's to fit.  You don't really notice them but if you do, they just like part of the installation.

I was concerned that if I tried to fill the holes, I wouldn't be able to reproduce the glossy finish of the gel coat and that would be more noticeable.

I think if anyone is getting kicked out it will be me.   I just re-sealed the Maxx Fan and used 3M Marine Adhesive Sealant - Fast Cure 4000 UV.  Found it very easy to work with... used painters tape about 3/16" from the edge and ran the bead very easy.  While I was doing that... I started thinking... Damn this stuff is WHITE!   I mean like BRIGHT WHITE.... 

Then the light bulb went off and just a little dab over the caulk in the old drill holes and it is now an acceptable level of whiteness for Donna.   So, no one has to sleep outside. 

Looking forward to seeing you at the Rally.  Maybe you will give us a quick tour of the new battery system.    #145 goes in to Easton in November.

We will be there on Monday. 

You will love the work that Easton will do for you.

Hey Scotty. Would you mind posting a few pictures of the air handler unit in the cabin after your new Chill Cube was installed, especially with holes you filled? As you mentioned above, there is a bit of difference between the Penguin and the Chill Cube inside. The Chill Cube is intriguing and seems potentially like a good choice, especially for energy management. And have you had much of a chance yet to try it out? I’d be interested in further reports. Thanks.

Scotty is camping and he might not have a pic before he filled the holes. I filled mine too but have this picture from before. You can see two holes in front and look closer to see two more on either side. The Dometic P2 was twice as big inside and out. There are two more in back 6" beyond the much smaller Chill Cube.

Notice the headroom too! Another reason it's quiet is the air handler/fan are not hanging down into the cabin interior like ALL the others!

Scotty got his installed at summer end, and he was only able to test the A/C minimally. He got the newer Heat Pump version and we hope to hear about that function soon. The link below goes directly to page 2 of my Chill Cube post which shows the installation. Pages 3-4 have some of my reporting on its efficiency. We ran ours all summer (all of 2026) and we just LOVE it!
