## Overview

Eastwood Internal Frame Coating Aerosol is a 14 oz black spray designed to both eliminate existing rust and prevent future corrosion inside vehicle frames. Featuring a phenolic resin and zinc phosphate formula, it penetrates hard-to-reach areas with a 360° extension nozzle, completing full rust protection within 24 hours. Trusted by professionals and backed by lifetime tech support, it ensures your chassis stays structurally sound and rust-free for years.

## Description

Your vehicle’s frame is a significant part of its structure, so it needs to maintain its integrity. That’s why Eastwood Internal Frame Coating Spray is the perfect way to stop rust from being formed on the bottom of your frame and inside the frame. the Phenolic resin in out product encapsulates the rust hiding inside the so it doesn't rust its way through and destroy the frame then the zinc phosphate seals the frame against additional rust. The entire process is complete within 24 hours and will help your chassis stay rust-free for years to come.

Review: I am very impressed with this product, insane coverage, go over the area a few times and you will have amazing coverage nozzle sprays 360 degrees. Make sure to wear proper clothing, gloves glasses face shield, longsleeve shirt, also tape off the holes on bottom of the frame to prevent making a huge mess. This stuff is very liquidy and seeps into all crevices. I would recommend this product to anyone looking for an internal frame solution. I blasted out the frame with an air nozzle and vacuum, and used a long wire brush attachment on a drill to clean it up best as possible. Better prep= better results. Looking forward to see how this holds up, I plan to cover it with 3M cavity wax plus after I am finished painting underside of car. For a double protection inside the frame.
Review: Based on Eastwood's Product reviews it should work just fine with a few coats.

## Questions & Answers

**Q: Is this resistant to sun/UV light?**
A: This coating is UV stable and able to stand alone without the need to be top coated when exposed to sunlight or the elements.

**Q: Can you spray on acid? Or do you need to neutralize acid first.**
A: You need to neutralize acid to spray it.

**Q: How long do I wait between coats? Clean nozzle between?**
A: According to your instructions, you apply one coat which will creep or spread to cover  the interior of your frame. This is easy because of the radial spray tip. According to your instructions, turn the can upside down and spray until clear. For cleaning the tube, your instructions read as follows IMPORTANT: To prevent clogging, after each use, invert the can and 
spray a few short blasts to clear the valve. Spray PRE or solvent through 
extension nozzle to clean.

**Q: Will Eastwood internal frame coating void any manufacturers warranties?**
A: I see no reason why it would. You’re not altering the frame but coating it for rust prevention that should have been done in the first place.
