This is great. Protects from moisture and road grime and looks good too. Nice matt black finish. Thanks for sharing this product info!

[@LakesideAutobody]

You're welcome Kenneth. I think it's going to be one of my goto products for undercoating for sure :)

@@LakesideAutobody since its a waxy finish does dirt and dust stick to it?

[@brucesheehe6305]

Just used some on the pumpkin and rear axle of my Chevy pickup truck. Looks great.

[@LakesideAutobody]

love the way it looks really - I like the satin or flat black :)

[@designsinorbit]

Man I'm right in the middle of both replacing suspension parts AND dealing with flaking poly on my porch! 😮😮😮

[@LakesideAutobody]

I did a front door with linseed oil - it faced the sun - never had an issue with it again - just added oil ever now and again :)

[@my357mags]

RP-342 will be looking into trying that out! Thanks!

[@LakesideAutobody]

Give it a try - I think for rust, it's one of the best solutions :)

@@LakesideAutobody I will! Thanks

[@michaelmarusic8499]

👍🏻Exactly what I was looking for, thanks for sharing this!

You're welcome Michael - like I said it doesn't get completely crispy hard but I'm fine with that as long as it doesn't flake or peel :)

Good show Jerry! Do you know if you can get a 360° tip for inside rockers etc.

[@LakesideAutobody]

I don't know but I'm still stuck on just squirting used motor oil inside repaired or new panels - check out this video on why - kzbin.info/www/bejne/r2GYlYGuqZKhjMU Thanks for checking out BB - have a great weekend :)

never herd of Cosmoline RP=342 black looks like great stuff if the military uses it , I am going to use it on my 2005 Blazer and my 91 GMC , thanks buddy .

You're welcome - I think you're going to love it. Easy to apply and just flat out works/looks good - too me any way :)

Thanks RG - you have a good weekend too :)

Another great video. Hmmm, I wonder if they will ship to California??? I tried to check but did not want to enter my email address. Maybe some time in the future.

Should I spray it on my frame or roller brush it on

Thanks Jerry, looks like the way to go.

[@peglegtoo]

Is the material tacky at all once it dries? will it come off on your hands as you handle parts? also, anything different between the two materials other than the color?

[@LakesideAutobody]

It will rub off a bit on your hands but I wear some rubber gloves when assembling the parts - it drys firm to a hard waxy like coating. The materials are the same other than the color. It is not tacky though after some time - in other words you won't have things sticking to it :)

[@chrismorrison9140]

Jerry if you get the Prothane trunnion bushings be careful with the setup of the vertical bushings, they are too long and need to be trimmed down to work.

[@LakesideAutobody]

Thanks for the tip - I did end up ordering the original rubber rebuild kit. Any other things I should look out for? Does it matter how the springs are positioned - not ends but rotational?

[@johnpappas2060]

Bless Good educational video. Thanks 😊 for your effort.

[@LakesideAutobody]

You're welcome my friend - thanks for the support and comments :)

[@gm-lb9oe]

Thx Jerry. I take it, you just have to spray it on bare metal or steel?? What would happen if someone painted their undercarriage, would you spray that on top, or not a good idea? Have a great weekend

[@LakesideAutobody]

You can spray it over the top for sure but you don't have to paint first. It works well both ways as long as the paint has been applied correctly and is not flaking off :)

[@BruceLyeg]

Am I weird for liking the smell of RP-342 Black? I buy it in cases of nine cans per case. I used to buy it by the gallon but I like the convenience of the spray cans. That AMX is gonna be a pretty driver when you're done. Have a great weekend, Jerry

[@LakesideAutobody]

Hopefully I keep it on the road :)

[@waynebeck7801]

This might be a good way to prevent replacement parts from rusting..coil overs etc. they look great when they are first installed until a couple of winters

[@LakesideAutobody]

One good thing... you can power wash the parts in a few years and reapply and it will look great again - no sanding, sandblasting, scraping, etc.

[@designsinorbit]

Question- would you paint new parts first, then use this product? Or no paint at all?

[@LakesideAutobody]

The greatest thing about this stuff is no paint at all! That's the idea behind the flat black. Matter of fact it's better not to paint as the paint will just flake off eventually and cause other problems

[@user-2Hteyasizyc]

Always nice info.

[@LakesideAutobody]

Thanks for watching U1 - have a great weekend :)

[@BCole-bj4lv]

Wow, I never heard of this product. I wish I knew about it sooner. I just finished spraying all my cars with Fluid Film. Have you ever used this over rusty parts in the past? Does it work on more rusty cars?

[@LakesideAutobody]

I've heard stories from service guys that it was used on war planes, guns, etc. and like 50 years later the stuff was still good so I gave it a try on a new truck frame. I love it so far. I have used it on a rusty undercarriage too and it's holding up well so far. I can tell it's going to take many years before you'll have to re apply. I'll do future videos on the longevity of the product as well :)

[@BCole-bj4lv]

I had heard of Cosmoline before, now that you say that, I realize my father talked of cosmoline. He was in the army air corps in WW2. I have to try it. Thanks for the info. @@LakesideAutobody

[@marcellemay7721]

I like the Fluid film. Its not quite as durable as the cosmoline. The cosmoline dries to a wax like consistency, where as the fluid film is kind of a greasy consistency when dry. The great thing about both of these products is that you can spray them right over surface rust and it'll stop the rust dead in its tracks. The other nice thing about the Fluid Film is that it'll creep into cracks and crevices where as the cosmoline won't. I think the cosmoline probably looks a lot better but the fluid film provides better protection in those hard to reach places but it probably needs to be reapplied more often.

[@BCole-bj4lv]

Ah, ok I will try it on the spots where the Fluid Film washes off this winter. We'll see how the cosmoline does. I noticed the Fluid film seems to disappear quickly from the hi-splash areas. Thanks. @@marcellemay7721

[@scottmallory3507]

I am 58 and getting my first new car ever in 2 weeks, a 2024 mazda cx-5, and I want it to last at least 20 years. I'm in Quebec where they salt the roads this time of year. I was planning on spraying all the metal suspension parts with fluid film as soon as I get it home but now you have me wondering if this cosmoline rp 342 might be a better way to prevent rust? What would you recommend more? Also thank you for all the help you've given me to do body repair and welding on my 99 miata.

[@LakesideAutobody]

Do this for the insides of the doors and other hollow panels - it works the best by far and is free - kzbin.info/www/bejne/r2GYlYGuqZKhjMU Use Cosmoline RP342 (Clear) for the bottom of the car. Keep all leaves and needle off of it and make sure seeds and stuff don't get trapped in the panels clogging the drains. The panels have to drain and the bottoms of them have to be greasy as there is no paint in the pinch welds at the bottoms of panels such as doors, hoods, decklids, etc :)

[@scottmallory3507]

I just watched your video on rust prevention and I'm going to that on all the doors, hood and tailgate. I'm also going to order some cans of the cosmoline rp 342 clear you recommend. Thank you so much! 👌😄

Good explanation. Thanks Jerry .Good video as usual. Have a good week.

[@scottmallory3507]

Have you tried the cosmoline 42 in the bulk gallon can in either a spray bottle or a compressor spray paint gun or do you prefer the aerosol cans? I would think it may need to be thinned down a bit with mineral spirits but a gallon can would last for years of applications.

[@LakesideAutobody]

I have not tried it. I'll probably try it out one day and do a video on it - I really like how this stuff looks and dries myself - depends on the individual I guess. I'm not one for shiny thick paint on the undercarriage.

[@reddemon1729]

I have two metal plates for an 68 amc amx and I have no clue where they go could you help me out?

[@LakesideAutobody]

Sure - email a picture to schoolvideolibrary at gmail - Jerry

[@WilCoxon007]

Could you apply this over the power coated new parts for added protection? Or do the parts need to be stripped to metal before application for it to work properly

[@LakesideAutobody]

You can put it over powder coated new parts. You can put it over anything really. It just sticks and doesn't come off. Only way to get it off is mineral spirits or similar.

[@jimurrata6785]

Actually oils like tung and *_boiled_* linseed do polymerize. (that's why they are called 'drying' oils) Just like an alkyd enamel paint cures because the oxygen causes the resins to crosslink. The point of your video is not lost on me, and regular, or "straight' linseed oil will take decades to cure if not out in the sun. Have a great weekend Jerry! 👍

[@LakesideAutobody]

You too Jim - thanks for the information. Enjoy the weekend my friend :)

[@mack606]

Is better to spray it on or brush it on your frame

[@LakesideAutobody]

I like to spray it - you can get a much more uniform look. Never brushed it on though so I can't really tell you what that would look like. Let me know if you brush it on how it works for you :)

[@mack606]

@@LakesideAutobody I decided to spray it on and thanks for the feedback

[@frankkennedy5361]

Jerry, Could I use POR15 or Rust Restorer to “arrest” a rusted area and then use Cosmoline over it? Inside of my “new” 55 trunk floor has surface rust I want to treat before top coating.

[@LakesideAutobody]

Absolutely - both products are probably tops when it comes to preventing rust. POR15 is great in the way it soaks into and grabs onto rusty metal and COS is a waxy coating that seals out moisture and never comes off. Thanks for watching Frank - have a good weekend :)

[@frankkennedy5361]

[@hickeyskustomresto]

I cringe at waxy products in the bodyshop, but if you're using it it's likely fine. Does it clean off easy enough if you're a little messy over an area to be painted later?

[@LakesideAutobody]

It cleans off easy with mineral spirits - in fact, it can be removed with mineral spirits too. You're right about grease, wax and silicone in a body shop - no good. Fast food too!

[@hickeyskustomresto]

@@LakesideAutobody It looks good. I'll be ordering some asap. You can't paint everything might as well use that. Cleans it up nice
