I ordered the road rash kit because my front bumper looked like crap. I paid $73 with shipping. I don't feel like spending $500+ to have it repainted right now, so this will have to tide me over until then.
This is the kit
The whole process took me about 3 hours, taking my time and letting the paint dry. Even if your bumper is as bad as mine, only do a small section at a time, it will save you a lot of work.
Here's the bumper after being washed
The first step is to use their custom mixed paint and the supplied squeegee and smear it all over (HINT: just put on a rubber glove and just use your finger tip. It's easier, faster and will save you A LOT of polishing later).
You're truck will look like it's got truckin' pox
After you've laid down a first coat let it dry for 10-15 minutes or so (Use this time to go around the truck and fix any other rock chips or small scratches you find.
Move on to Step 2, polishing with Sealact, which removes the excess paint. This step is a lot of buffing, but gently. The kit supplies a soft towel, similar to a Scott Shop Towel. Dampen the towel (I found an old t-shirt works as well) and with a flat hand rub across the paint spots with light-medium pressure. You want the chemical to do the work, not your arm. But it is still a lot of work. After using the Sealact there will be a little hazing, just use the supplied microfiber to polish and it comes right off.
The smaller chips and scratches should be mostly, if not completely covered. Larger chips like the ones below will need a 2nd, possibly 3rd application.
For the 2nd and 3rd application I ditched dabbing with a glove and used the small brushes supplied in the kit. here, you just dip your brush and dab the chip to fill it up.
After 2-3 coats, this is what you end up with.
While it doesn't look like a complete repaint, it's a decent touch-up job done for less than $100. I still have about half of the bottle of touch-up paint left and may go over the chips again just to fill them in a little more.
