When you ask what's the best, you can't really get a good answer without a price tag affixed. In NO WAY is herculiner the "best", it's a decent quality product and comes at a relatively cheap price. If you're not so concerned with price and more worried about the best, go get Rhino or Line-X sprayed on. If you're more like the rest of us broke *** Jeepers, I'd say look at the U-Pol Raptor, it's more expensive than the Herculiner but does seem to give better results. (You can get a spray kit, with gun and all for about $100) I herc'd mine and spent 3 days prepping it and it came out great, I ended up putting two coats everywhere but directly under the front feet and there I put 5 heavy coats. My heel wore through the front with no floor mats, I'm sure with a decent cheapy set of mats that wouldn't have happened. Just a heads up.
