I will try to help you out, but I have never dipped my skid plate "I have an RCI front Skid", but don't see it being to overly difficult. I'd say since the skid plate is a high traffic area you'd want to hit with at least 8 coats, I'd tape up the lettering and try to get the lettering taped off the best you can, I have yet to get a perfect line with plastidip but have came close. I'd say get four maybe five cans of plastidip to be safe "I like to have too much of a product then too little". Once your done with your last coat, give it about 20 mins and while the dip is still tacky use a box cutter, a tooth pic or whatever to peel the tape off of the letters. Then I'd let it dry for 8-12 hours then put it back on the runner take pics and post them on here.
