Enclosed Trailer Floor Coating

Out of curiosity what is everyone using on the floors of their enclosed trailers?

This stuff is the best.  I used to build custom trailers for a living and this is all we would use.

I laid luan plywood over the existing floor and coated it with garage floor epoxy. Turned out really good and has held up for aboit 10 years now. 

I just used some porch paint with additional grit added to it. looks good but time will tell how it holds up

I just used the garage floor epoxy kit from HD. It has held up well for the last 4 years or so. But, the trailer only gets used for 5 or so weekends a year. No complaints with my use case and it was cheap and easy to install. Use a lot (and then add a lot more) sand when painting the ramp. That stuff is slippery when wet. 

In reply to TR7 :

Just wondering, why the luan first? My plywood is smooth enough, I would think?

In reply to 03Panther :

I actually had to think to remember why I did that; the original floor was a combination of oil stains and vinyl tile adhesive. Zipping luan over it was the quick and easy way to a clean surface.

So you might not need it, but somehow when responding my brain went "yes, of course put luan down first. No further elaboration needed." 

In reply to TR7 :

Makes perfect sense. I've used luan for a ton of stuff, going back to when it was $8 a sheet, and almost 1/4". Still use it a lot. 
I certainly was not being a smart azz when I asked. Genuine interest. 
Thanks.
