under coating

Can anyone tell me what the factory did in 1960's for under coating a cj5 ? I would like to know so I can do the exact opposite!

 

Did they undercoat the CJ's?

 

Don't know what they used for undercoat, but if you are trying to remove old undercoat, Jasco Epoxy Paint remover/Stripper works great.

 

I don't believe any of the auto makers were using undercoating in the early 60's.........they relied on primer and paint to protect steel. ON some of the old 60s vehicles I had growing up I had to use aftermarket rattle can undercoating on the tin can and sheet metal patches I riveted in place so I would no longer see day light through the floor

 

I agree with what has already been stated above. I've never heard of a factory undercoating from that era, so most undercoat applications were after market additions by a previous owner.

 

Thanks for the answers . Any suggestions for undercoating that is good and cheap

 

I don't undercoat. Here in the salt-belt we "oil" annually.
Some use waste oil but Penetrol works well, drys hard and invisible. Use a garden sprayer or a cheapo undercoating air gun from JC Whitney, with extensions to get into the cavities.

 

rustoleum

 

When I redone my Jeep I brush painted the underside and the interior with Chassis Coat, after sand blasting it. The Auto Parts store where I do business recommended it to me. It is a super hard finish, and dries to a shinny smooth finish. It has been seven years now in a sandy area of Northern, Lower Michigan, and the floors have not worn through. It is a little costly, $50.00 a quart, but there are no worn spots, or chips under the fenders.

 

I was using Hammerite for many years but the last batch I bought does not seem to adhere the way it used to.. I don't know if they changed formulation or what but it just does not seem to be what it was..

 

I had Hammerite in 'stock', drying in 15 minutes, etc... I bought a new can and it is not the same formula, IMO.
Drying is very long, not the same 'smell'...

Probably that the old formula was dangerous or not legal now.

 

Hey PeteL, tell me about this Penetrol. Sounds like something I may be interested in, I don't want to undercoat.
Is it a spray can?

 

Check out fluid film. Biodegradable non toxic and works amazing. Oh yeah cheap too

 

Sold as a paint additive, quarts and gallons, at hardware stores, etc.. Also has metal-protection qualities, which the company promotes more in other parts of the world.
Penetrol is the oil-based version (Floetrol is for latex paints) - made by Flood.

Shoot it on wet and heavy, it drys to a sort of sticky clearcoat. A gallon would probably do two jeeps.

 

The only advise I can give you, is to stay away from any spray on bed liner that does not include some type of a harder (like the ones out of a areosol can). They always look great at first, but in my experience they don't hold up well over time; but I know bed liner is a popular choice out here on the left coast.

 

That what my local paint shop recommended. I'm gonna try it. Seems like somethin that should b applied every year or so. Old undercoating dries and cracks so seasonal application is necessAry anyhow.

 

Waxoyl was popular in the UK......it is a clear waxed based undercoating that you spray on warm to coat chassis etc and into crevasses.
I believe it is available in the US. Have a car from the UK that came treated with the stuff. Can remove it with hot pressure wash or steam.

 

Yup put the fluid film on annually it's also a good penetrating oil.

 

Firing up an old thread do not one can say I didn’t search

Anyone have experience with the rust-oleum undercoating spray? Thoughts ?

 

I used Stone Chip then painted it base cost, the same color as the Jeep, then clear coat.
