Eastwood Internal Frame Coating

How Frame Coating Works

Eastwood Internal Frame Coating destroys rust hiding inside the chassis so it doesn't rust its way through. You spend time and money restoring a chassis — but what about all that rust inside the frame? Apply our rust coating spray to make your chassis rust-free throughout! Tough phenolic resins penetrate, convert and encapsulate the rust on the internal surface. Zinc phosphate then seals it to prevent future corrosion.

Eastwood Internal Frame Coating

Each can of Internal Frame Coating comes with a special 24-inch tube that reaches inside the tubular steel bars and frame parts. This tube has a conical nozzle with multiple sprays, which reach outward to completely cover the innards of the metal. Tough phenolic resins in this coating then penetrate and encapsulate the rust on the internal surface, preventing it from spreading. Zinc phosphate seals it to prevent future corrosion. This special coating cures within 24 hours, leaving you a frame that's strong inside and out even in the subframe and cavities.

Rated 5 out of 5 by from Easy to use with flexible tubes Can't know for sure how it covered since it's inside the frame but seemed to have a good 360 spray. 2 cans did an 11' jeep frame, one can down each rail.

Rated 5 out of 5 by from Great Product I bought Internal Frame Coating Plus with nozzle and did my internal frame on my 2001 Jeep Wrangler TJ. What a great product and easy to use with no problems and the frame inside turned out nice. I would highly recommend this product for doing internal frames. Also tape up all holes that is not used for access for spraying in which I forgot one on the bottom of the frame and coating ran out

The internal frame coating spray has a 24 inch tube applicator, I believe. I really need about a 48 inch hose. Can I special order this?

Asked by: Dean
A 48" nozzle is not available. It would be a trial to see if the product would travel sufficiently through that length of hose.

What is the difference between the Internal Frame Coating & the Internal Frame Coating Plus?

Can you use this product on the inside of the framing of a hood and truck? Will the heat from the engine be an issue?

Asked by: Drew
Eastwood Internal Frame Coating is not high-heat rated, but it can tolerate moderate heat, up to around 300°F (149°C). This makes it safe for most inner hood framing, as long as it's not directly exposed to the engine or exhaust heat.

What is the difference between the regular and plus internal frame coatings

Asked by: KRTRDR
The Plus internal frame coating is a stronger, longer-lasting version of the regular one. It offers better rust protection, especially in harsh conditions like moisture or road salt. Use Plus if you want extra durability—regular is fine for light or occasional use.
