You will also be able to watch five On-Demand videos that Kent has specifically filmed on how to use this amazing product to seal and stop rust, as well as repair small non-structural rust holes using POR15 and fiberglass cloth. (Note: these can be viewed from any computer when you are logged in to your account at Mercedessource.com) . Some of these videos were filmed a few years ago and mention the use of Miracle Paint. POR-15 has very similar properties, and the preparation and application procedures are the same. We have prepared a special supplies kit that includes brushes and two types of fiberglass cloth to aid in your repairs. Please see related products below to order separately.

Here is the repair sequence of one of the more common rust repairs that this product excels at - rust in the wheel wells. In fact, doing the repair this way is better than trying to weld in new sheet metal. Have you ever witnessed how rapidly welded steel can rust? If you can not get to the back side of a new weld to treat it will a product like miracle paint it will rust out again from the backside in 4 to 8 years if it is exposed to moisture.
This typical rust spot that you might find in a wheel well area doesn't look too bad does it... just remember what you see is always the tip of the Rustberg... This is n example of why I detest body undercoating. It allows moisture to get trapped in behind the coating and actually accelerates the rust out.
When you start scraping away the undercoating and flaking metal, the hole will always be worse than what you first expected.
Once the damaged metal has been fully exposed you can continue scraping and rough sanding the surrounding metal to an area at least 1 to 2 inched past the weak metal.
Coat the area inside the hole thoroughly with POR 15 to prevent further rusting, then make a patch of 3 layers of fiberglass mat soaked in POR 15 Paint and apply it over the rust hole. When dry overnight you will not believe how strong this repair. Even banging on it will make you think you are banding on sheet metal. It dries as hard as epoxy but will not let loose from the rust like epoxy or polyester resin. It really is a miracle!
When the POR15 is dry, you can skim coat it will a waterproof filler, sand the area and then spray it with our high-quality chip guard (do not use typical auto body undercoating. Massage it a little and you can even make it look old and original.
On another note, this product works great on repairing holes in mufflers and rear exhaust pipes. Just try to find ANY other product that can do that and have it last. I have done repairs on mufflers that have outlasted the life of the muffler itself!
