I really, really hate you
My undercoating takes SOOO much longer since I'm on my back, lol! I got sidetracked into another small project on my FC so the rest of my undercoating is being held off a bit for now, but should resume shortly.
You should be able to knock out the herculiner in a day no problem with that setup... although, your undercarriage appears in worse shape then mine... I only needed minor repairs thus far... good luck man...
