I recently upgraded from the wollwax pro gun ($99) to the lemmer rp460hd and couldn't disagree with you more lol the lemmer gun sprays 10x better than my wollwax gun ever did and with the pressurized pot no need to warm up the product anymore, it cut my job time in half because it sprays soo much faster , and you adjust the air with the regulator and the product on the back of the gun, I fill the pot with a 5gal pump dispenser works great no funnel necessary and no mess, no to mention the cavity hoses are half the size and fit into waaaay more openings!

Do you have a link to that aerosol can spray wand?

[@zw7453]

Almost every single inner cavity 360 spray extension nozzle are made for MALE !!!!!! TOP !!!!! SPRAY !!! CAN !!!! NOT FEMALE!!!! Now Surface Shield has female tops on the can, it is IMPOSSIBLE to find any inner cavity extension without paying a ridiculous amount of money for a plastic tube and a brass nozzle!

​@@RepairGeek ​​​​​​​​​ i own this lemmer gun The air is adjusted using the air regulator and the product is adjusted using the knob on the back of the gun. You are correct its a 2 stage trigger but the second stage the one that dispenses product can be adjusted up and down with that knob on the back of the gun. You adjust both settings together to get the results you want maybe you do not have enough air pressure? This gun works great once adjusted correctly so im not sure why you keep saying you cant adjust the product flow when there is a huge knob right on the back of the gun for the sole purpose of adjusting nothing but product flow.

A tip for the ends on the end of the tubes. You can use safety wire twisted tightly around the hose to clamp them together and not increase the diameter so you can still get into the holes easily.

With the lack of hose clamp I use a bare single strand copper wire wrapped around the hose at least twice then twisted to tighten.

The reason the one sprayer releases pressure is to ensure that the user doesn't get a blast of product on them if they remove cup without depressurizing the unit. You get into a rhythm spray fill, spray fill, then you forget to release pressure and bam you are water prof. Good review. It has help me decided what type a unit I want / need.

[@RepairGeek]

I don't necessarily agree only because the Lemmer dumps pressure once you spin the canister about 1/16th of a turn. I agree about getting covered in product from a pressurized container but, the engineering could be better and it would be a non issue.

[@FredRobich]

Thanks for sharing all the details, great video! I went ahead and bought the Woolwax Professional spray gun and undercoated my Toyota Tundra with RP-342. Works really well and I think I'm set for life with that sprayer lol

[@Uticagreens]

I reside in Upstate New York State. We get the most snow of any State in the lower 48. We deal with mega tons of road salt, brine and calcium chloride. I undercoat with lanolin products on my trucks. My complaint is that it is difficult to transfer the product into the small opening of the spray bottle. The sprayer manufacturers should take the lead from the mayonnaise bottle makers. Seeing that the lanolin undercoating products are a similar consistency of mayonnaise, they should make the undercoating spray bottled opening the same width as the mayonnaise jars.

last year I wanted to spray my car, I tried a venturi sprayer. that didn't do it for me so I bought a pressure pot style gun. a really good one that is available here in germany. a 3300 HSDR from Vaupel. it took an hour or two to get used to it but on a sunny day with a tiny tiny compressor I had all things done in the evening. The gun is amazing I think because it also keeps pressure over hours in the pot. it is quite similar to your last one shown, also weirdly small opening but that's ok. I wouldn't want to use anything else anymore. buy cheap, buy twice. and only coat yourself

After doing my 1st ever undercoating on my '13 Sequoia and '06 Tundra with the WW Pro gun I realized I want/need a sprayer with one of those 45/90* wands because of all of the crevices and hard to reach locations (especially on the Sequoia)and those wands would be perfect for that and to be able to get to the top of the frames. I want to make this job a lot easier because I don't have the luxury of a lift. I am crawling around on the ground.

[@tyrel7185]

I bought the RP460 (I call it the Mack-Daddy) and start with the longest hose to spray inside all frame and body cavities then spray the outside of the frame and underside of the box/cab. I use lots of product and apply it fairly thick everywhere. I had 4 other sprayers already when I bought it and threw out some of them after using the RP460. It is the best at getting the most thick product the furthest into the cavities where it is needed most. Don’t cheap out here guys. It is an investment. Spread the cost out over doing 1-2 vehicles per year for ten years and it is sooo worth it.

Yea, but for those of us who are only doing 1-2 vehicles per year, it aint worth the price difference. You're literally spraying goop on the bottom of the car. Get that shit on there and be done with it, don't need some fancy spray pattern when in a week its going to be all black with dirt and oil and shit anyways. Professional wise I could see the argument for time saved, but for the typical DIY'er who's just getting under their car and glooping that shit on to keep their shitbox from turning into a rusted shitbox, who gives a shit if it saves you an extra 5 minutes or so?

Great review and without any waffle. Thanks

[@alexmoore909]

I have the same lemmer rp460hd I bought this fall for my own diy stuff. I haven’t had an issue spraying fluid film with it, although I like it good and thick under there. It’s my own so I paint it on good. I have been able to get it dialed down enough for light application with the air pressure and trigger modulation. The screw on the back is actually not air it’s for the fluid needle spring pressure you can have set so hardly anything comes out. I also pretty much exclusively spray with the wands for everything and don’t use the fan tips. The smaller smaller 90 degree one will spray out less than the Deluxe one. The one thing I do miss is a second container as I was running black and clear fluid film. My clear I had a 5 gallon pump but the black I was trying was just in the gallon cans so it was a little awkward to pour in. I was quoted at $120 for another pressure container which I’m debating on because I think I am going to switch to black for everything minus some visibly panel areas around doors and such.

[@alexmoore909]

Also I want to say thanks for your tests and reviews. It was because of you I made the switch from having krown spray my vehicles to me spraying them myself with fluid film. I’m fully involved now.

[@RepairGeek]

My biggest issue with the lemmer is weight. It feels like it weighs 3 lbs when it's full and holding that over your head for hours a day gets hard on your shoulders. It a nice gun but to me it's not $350 nice.

[@coreyg7364]

About compressors: You can get away with using a small single stage air compressor for something like this. Something like 4.7 or 5 gal works fine as long as its the kind with 2 tanks. I forget what you call them, but if you set them up properly they work like a 2stage and they will run a cup gun or gravity feed just fine. I used to spray contact adhesive through a cup gun with this setup, so I know it will work with undercoat.

Your vid’s have been extremely helpful. I got the Woolwax gun but the wands are too thick for doors and inner cavities. Do you know of any thinner wands which will fit or another gun which has thin wands?

[@RepairGeek]

The cheapest option would be aerosol with an adapter.

[@Spta97Vids]

Thank you. Seems in order to get a thin nozzle you need to get a pressurized gun. The Woolwax gun works great for the undercarriage but since it uses the Venturi effect it needs a larger diameter wand. So I’ve been told.

[@josephmckinnon3546]

How would you recommend washing the undercoating after applying the fluid film? I'm in Michigan, and I'm buying a new 2023 car. I want to protect it with fluid film, but should I not use a pressure washer to wash the undercarriage after applying it? If I should wash it, I read that people said it'd take it off... and if it does take it off, should I re apply it every 6 months.. every year? If you can help, I'd really appreciate your opinion and time.

[@ryanwilson3632]

I personally own the lemer 460 and the only thing I agree with what you said was that you can't adjust the fluid volume though. The rest your off base. Its primary job as a professional gun is to be used with wands. I recommend switching the gun and attachments to regular sized air fittings as there easier to come by and much cheaper. I've made many wands and by saying where the small angle one will fit in comparison to the deluxe swivel one is off the small one works great for getting in door bottom holes I went as far as cutting my small wand at a 45 degree right at the bend and smashed it together so it fits in the small door holes and atomizes to a very fine spray. I've put NH Oil, fluid film, and some wk sealout which isn't availible to the regular public. It's a great gun it's built to a much better standard then the other ones. It's not built for doing the entire underside of a car. It's built for cavities and crevices.

[@RepairGeek]

That is my point exactly. It works great for inner cavities but $350 is a lot of coin for a gun that is dedicated to inner cavities only.

I've got holes rusting through under my rear doors on both sides, from the inside, and want to be able to wash it out, to cut and weld patch panels in after snowmobile season. The rockers, and door bottoms were bed linered by original owner, so I didn't see it till I had some soft spots. Honestly we never used to have the rust issues here in Wa. So it really just didn't occur to me, until the last couple years. Spare tire carrier cross member, was the only area that had any real scale chunks.

[@BladePilot24]

Vegetable oil is what they (WW) say in their video.

[@johnguertin5054]

great job...as usual

[@dirkkelly9596]

Thanks for the info 👍

[@garyconley69]

any chance I can use my magnum x5 airless sprayer for this? thank you.

[@RepairGeek]

Probably but you'll want to make it a dedicated undercoating sprayer afterwards. I have no idea how these oils are going to react with paints.

[@garyconley69]

@@RepairGeek Got it. Thanks for getting back to me. and thanks for all the information you provide. Have a good weekend.

[@Ko3n3k33]

Did you end up using your Graco? If so how did it work and how was the cleaning process? We're you able to get everything out without having fish eyes when spraying paint later?

[@garyconley69]

@@Ko3n3k33 I have not yet. Planning on using it to undercoat a trailer once I get the trailer.

What do you use to clean out the sprayer, tips and wands?

[@RepairGeek]

Nothing. These lanolin products don't dry. So you can spray a car, put the gun on the shelf and come back to it a year later. No issues.

[@bdubs6205]

@@RepairGeek appreciate the reply! But say I did want to clean it out. What would be best?

[@RepairGeek]

Mineral Spirits.

[@MrRoadtrek]

What do you use to clean the sprayer?

[@RepairGeek]

I dont clean them. Any of the lanolin products don't dry so I can put them on a shelf, come back to it 6 months later and they still work perfect. As far as cleaning is concerned I wipe the outside off with a rag. That's my gun cleaning regimen haha.

[@acwright]

I usually use my hands or pour it over from the roof and let it drip in. On a hot day, it gets in all the cracks.

[@Haran_Zagury]

Hi, what about HVLP sprayers, Specifically devilbiss flg 6? The gunman KZbinr highly recommend it

[@RepairGeek]

I'm not a big paint guy. I have no opinion on paint sprayers.
