Underbody
 

I am about to primer my 67 camaro after finishing all the metalwork and was wondering what everyone thinks I should put on the bottom of the shell. The car is on a rotissere so this is the best time to primer/ undercoat the bottom of the car. Maybe some POR15or some other product that I have not heard about. Thanks.

have you checked out second skin?

I'm thinking I might use epoxy primer followed by U-pol Raptor bedliner. I used this stuff on my truck and although it seemed a little too thin for a bedliner, I think it would make an excellent undercoating. Do a search for Lenie in the project updates section, he used it on the underside of his 68 Firebird.

I'm close to doing the same on mine and was wondering the same thing, like to hear what others have to say. I was thinking epoxy or POR-15 followed by some sort of bedliner.

Although I have not quite got to the uncoating stage, I believe I may try this approach. I am surprised more have not gone this route.

Por-15, I have been using it everywhere on my build and am really happy with the results. I am very skeptical of any kind of body deadner/bedliner. The reason that i say that is that most rust problems i have seen develop underneath cars are due to the deadner cracking after time and trapping moisture underneath.
Go the Por-15

for rust protection there is only one way to go and that is a wax based undercoating... but it is a mess, and doesnt earn you street credit

the first thing applied to the metal should be epoxy primer,then whatever material you choose, stay away from POR-15 unless you want to strip and re-do everything in couple years

Was that stuff textured like bedliner or smooth? I couldn't tell for sure, but it looked like paint to me. If so, I like the look.

Travis77 I just watched the videos of the bedliner. That looks like it would be great. Thanks for the link.

I like this product alot. Nice texture..:cheers:

Me too, and you can't beat the price either :thumbsup:

Your welcome guys. It's a rare occasion that I get to help others out here. Like stated earlier, I think I will epoxy coat, rough up a little, then try this semi-smooth underbody coating. Who ever completes their's first, please post pics.

Have you checked out this build?

I believe that's Raptor bedliner:cheers:

I use Raptor coating on most our builds and love the durability and texture. Make sure you have a clean well prepped surface though, I have seen it pull away from a concave curve from shrinkage. You can also tint to match, solids match the best, metallics are a off a varying amount depending on the color chosen. It is pretty close to a pebble grain if shot correctly

would u want to use raptor liner on the sub frame as well, or just leave for underbody and trunk?

That's my plan. I'm either going to paint my subframe with this ceramic chassis paint I saw at Eastwood.com or have it powdercoated.

Several years ago I owned a restoration shop in Central Texas. I used Speedliner bedliner material as an undercoating for several muscle cars, trucks, and jeeps. I highly recommend the Speedliner product. The material had the best UV stability and color fastness of any of the bedliner materials at the time and believe that may still be true. I sprayed the material into engine bays in black for several muscle car/classic cars that the owners drove alot and wanted something that was easy to keep clean and still looked good. I did the complete underside, engine compartment and interior of my best friend's Chevelle SS @ 8-9 years ago and it still looks new. To my knowledge all of the other owners are still happy with their choices and still have had good luck with the Speedliner material too.
The texture of the material can be varied somewhat by the operator if they know what they are doing. It will still have a textured finish because of the spray equipment used to apply it, but you can change the texture from fine to extremely course. Personally I always sprayed it as fine as possible to give a semi smooth finish, that way very little dirt, etc gets stuck in the texture normally.
The Speedliner material has a slick urethane feel to it (it is 100% Urethane) so it gets extremely slippery when its wet, but this helps to keep it from getting dirty and worn out like some of the other bedliner materials out there.
Generally the Speedliner was applied to a painted or sealed surface that is scuffed up prior to application. Good prep and cleaning is the key to making the Speedliner or any bedliner material stick. The other big advantage to Speedliner was that it had/has very little shrinkage during curing.
Hope this helps anyone else that is looking at using this option as an undercoating.

i would not use on sub. texture will make it look like you are covering something up. I have a 70 Mustang SCJ in the shop now and that is exactly what someone had done to camo old wreck damage.

MacroPoxy
 

I used a product called MacroPoxy a 2 part industrial epoxy to seal of the wheel houses on my project. This stuff is what they use to seal water towers with and seems to have incredible duarability. Goes on via a roller or spray can be thinned, or tinted. You can pick it up at Sherwin Williams.
The flash from the camera throws off how uniform it went on with a roller. How ever i would spray it on for the best finish. It can be topcoated also if you need.

You are correct. Raptor

Might be careful with this web site and video guys. (from page 1)

LINK REMOVED

When I ran it - it dropped a file in my documents and setting/temp internet folder that was detected as the JS/Wonka trojan by McAfee. Might want to scan your pc just to make sure.

yep me too!

I used Line-x on my El Camino. I shopped around at several of the shops in my area and found a big difference in price. The shop that did it was the best price and showed the most attention to my needs before and during the process.

I went with Line-x and masked and painted the rails. It was a total bizznatch even on a rotisserie! I had something like 6 hours into masking alone. I really liked the way it turned out though and should be bullet proof for a long time. I blasted the bottom with a pretty course grit just to give the material extra bite. You have to be careful with drainage though.

I use SPI www.southernpolyurethanes.com bedliner on the bottom of cars and inside the trunk in my shop.

Not sure about the bed liner?
 

I have been following the thread and trying to decide which way to go on my car. There is no question that it looks great and is bullet proof. My biggest problem with any bed liner material is the major PIA that is involved in removing it if there is any work to be done down the road or repair due to collision etc. Same comment can be used that the coating hides cracking etc? Can anybody comment on working on it after the fact?
