rust and rust chunks on/inside frame - 2019 XLT Super Crew

[dmjr77]

Has anyone run into any major rust issues on your frames?

This afternoon I was in the process of washing off the thick mud from the underside of my 2019 (its mud season). While I was hosing it off underneath, I always stick the nozzle of the hose in the holes in the frame to wash out the sand and debris. When I did that, I got a good amount of sand and then lost of rust colored water and a lot of rust chunks. Has anyone experienced this?

I purchased the Waxoyl undercoating system (which treats the inside and outside of the frame) back in 2019. I have gotten it touched up in the spring and fall every year since I have owned it new in 2019.

Just wondering if anyone has experienced this.

I used to undercoat as a side-hustle. That's pretty common, that sand and debris acts like sandpaper in there and wears off any paint that's in it. Plus, the dirt holds moisture and NEVER dries out.
I'm not familiar with Waxoyl, but I never undercoat with anything that even remotely dries . The three major players are Fluid Film, Wool Wax & Surface Shield. They don't dry and they 'self heal' by creeping and stand up to stone chips etc. Something that dries will get a stone chip and you're done for.

Agreed: Unless a cured coating has been applied to a properly prepared base metal, moisture can and will creep in through worn or cracked areas. Once that starts you've got deteriorating metal hidden from view. Thumbs-up for Fluid-Film (used by the Navy since the 40's). I used it extensively on both steel and aluminum equipment surfaces exposed to fog and salt air around the SF Bay Area and the coast. Even anodized and powder-coated metal will eventually succumb to moisture.
