RMP's (Real Milk Paint brand) Outdoor Defense Oil?

I haven't even heard of it.....:ROFLMAO::ROFLMAO:. But I don't get out much...;) I have heard of the company itself, didn't know they were offering this product.
I don't see any of the ingredients being a strong UV blocker if any, so keep that in mind. I would research any rated oil that actually shows a Chemical or Chemical Compound in the material data listing as its UV ray resistance. Otherwise, you're just putting oil on to make it look good, with little protection from the rays of the Sun.
 
As far as I know, oil finishes are never as effective as other clear finishes such as varnish or poly. A quick Google search seems to bear this out. The AI summarizes.


While oil finishes can offer some UV protection, they don't typically match the UV resistance of other clear finishes like varnish or polyurethane, especially for long-term outdoor use. Traditional oils like linseed oil offer limited UV protection, but newer, "next-generation" wood oils like Osmo UV-Protection Oil incorporate UV absorbers to enhance their protective qualities.However, even these advanced oil finishes may still require more frequent reapplication than film-forming finishes like varnish, which provide a more robust barrier against UV rays.


  • Enhanced UV Protection:
    Some modern wood oils, like Osmo UV-Protection Oil, incorporate UV absorbers and light stabilizers to better protect against UV damage.
  • Improved Durability:
    These advanced oils can offer better protection against UV rays and may require less frequent reapplication compared to traditional oils.
  • Still Need Maintenance:
    Even with UV absorbers, these oil finishes may still need reapplication, especially on surfaces exposed to intense sunlight.
 
In my past experiences working with outdoor clear oil finishes is that they are food sources for mold especially if your project does not get morning sun. When applied to clean wood in good condition and in the right environmental conditions they do look great. Just be careful if using this on hardwoods as they don’t penetrate very deeply and therefore you can wind up with a sticky mess if over applied.
