Rated 5 out of 5 by from Very Good Product I have used this product several times now... I really like it... Very fast drying time... My most recent project was a new 22 foot enclosed car trailer... I put the trailer on the hoist and used 10 cans of the undercoating (more than enough) on all metal parts and now it is well protected for years to come... After the undercoating was dry for several days,, I spruced up the metal frame work and changed the color from the poor quality black paint to a red paint (white trailer,, Red F-150) of good quality... Down under the trailer the new paint holds very well to the dryed undercoating... I don't use the trailer in the winter so it should last a long time... Getting ready to order more just to have it around for the next project... I say go ahead and get those projects done... JUST DO IT......

Rated 4 out of 5 by from Good product, easy to use Used this product to undercoat my panel truck. I used the Eastwood spray gun for this particular application and is easy to use; just shake can good, attach spray gun and shoot. My only complaint is that their shipping department needs to better package the product; they put the product in the box with only packing material on the top and no packing material on the bottom, thus cans arrive dented... doesn't affect product but is annoying to be shooting paint from a dented can....

Rated 5 out of 5 by from Excellent! Just did my 4th car with this product and I find it very easy to use and clean up is a breeze. I just screw the gun on the can and only use the plastic bottle for cleanup. Make sure your car is clean and as high as possible on jackstands to give yourself more work room. Mask everything you don't want coated. It applies just like a spray can of paint. Spray from every angle, then come back from another angle and spray the areas you missed. Great product, I'll use it again.

Rated 5 out of 5 by from Great Product I have used under coat products before. This product is great. It dries quickly, looks great, and covers very nicely. Purchase extra because you will find more areas that you want to cover than you first thought. You will need to thin the product with a little solvent to get it to spray easily.I also bought a couple aersol spray cans. This allowed me to get into some tight areas with more precision

Rated 3 out of 5 by from Decent product, but a hassle to use The product it self is pretty decent, but due to incompatibilities with item 20441 I can't give it 5 stars. The container that the undercoating comes in is a 'tall' quart. The gun only works with the 'short' quarts - the pickup tube is too short. And you can't use the plastic bottle that's on the site either. So all in all a lot of hassle in trying to get this product to work.

Rated 5 out of 5 by from Great product The first time I used it was on the inside floor pan of a 1968 Camaro . When it dried it looked great a really nice black not to dull,covers great .so I ended up ordering more for under the car. Since then this product is all I use on all my restorations, all my customers love how nice it looks. I highly recommend this product

Rated 2 out of 5 by from Wouldn't spray I have the Eastwood undercoating spray kit (50369 ZP) and have never been able to get the rubberized undercoating to spray. It clogs the wand of any length, even tried thinning the product out with no luck. Either I'm missing something or the product or sprayer is no good.

Should this be applied to a primed surface or is it better to apply directly to bare metal.

Directly to bare metal would be the best for the undercoating.

Would this product help prevent any heat buildup in the cab of my cherokee from the exhaust or help with sound deadening? 

Asked by: Tim A
This product will offer a little sound deadening. An option is our ThermoCoustic which can be used inside the cab for noise and heat.

Can this be applied over bare metal?

Asked by: Sandman
Yes, the metal would need to be etched (blasted or scuffed) and cleaned off with Pre painting prep, before applying.
