  • We hit our first Milestone! Over the weekend we surpassed 100 subscribers! I just want to say thank you for watching and subscribing! I'll make every effort to continue posting weekly videos and providing the best content I can. For those of you that don't want to wait till our next weekly update please enjoy our complete time-lapse of the Undercoating project we did on our 1978 Datsun 280z. We started off trying to clean up the existing undercoating and realized it was just too far gone to be fixed so we decide to strip it down to bare metal. We then cleaned up all the bare metal using wax and grease remover, a tack cloth to get all the dust particles off right before laying down two nice coats of Southern Polyurethanes 2 part Epoxy primer. We then sealed all of the undercarriage seams using 3M Fast n Firm Seam Sealer and put a third and final coat of Epoxy Primer on top of the cured seam sealer. After the Paint was dry we Finished off this project with some of the toughest DIY Undercoating product you can buy. Typically used as a Truck bed liner, We went with Raptor Liner as our undercoating product of choice. It's durable and provides good build for protecting your undercarriage with a nice and new uniformed look. If you are looking for Datsun parts, don't forget to check prices on DatsunPartZ.com

    I just putty knife hand scraped mine off two Z cars it mostly Fell off from the hot and cold gathering and holding dirt cycles it accumulated over the years.
    Was rather quuck and easy on both cars. I used the same method inside for the tar sheet sound deading material and a small hammer and stiff heavy duty putty knife.
    Went rather fast as it was brittle from age.
    You did LOTS if work it has paid off.

    Well, the comments say 1978 Datsun 280Z. Without the bumpers, I could not tell. Thank you! I was working at the only dealer in a capitol Midwest city. The sold other European brands but my service mgr. asked me to take these new test for 5 cents per flat rate hour for each I passed. Took all eight & passed. A few months went by, a package came with NIASE Master Tech. These were cars I really loved and owned a 1976, first year after 260Z and had fuel injection. 6 cylinders with 7 electric injectors just like those used today, just clamps on hoses. The 7th injector was for cold start, controlled by a simple “Thermal-Time” switch screwed into the coolant jacket near the front of intake. They used a main fuel pump frame mounted with a pusher pump inside the tank. 1977, they down tuned the cam, dropped compression a little and put a gear reduction starter. House fell a little. Thank you for saving this one. Currently, I own a 1969 1600 Roadster. Convertible two door, power bulged in hood, live hood scoop, recessed headlights w/chrome buckets, disc on front, aluminum finned cast steel drums and full box frame. If you put an MG Midget or MGB on a lift, they flexed so much, you could not open the doors. Datsun did not do that. Over the years, I had diagnosed the root cause and fixed everything from bumper to bumper. I had poly glass wider tires on turbo mag wheels and have hit 130 MPH on a open highway, ran smooth a glass. During the video, you used 5 of everything (Ha ha! But a lot) I read your list but researching for a water based wax & grease remover. I saw the SPI and not sure if solvent base. Could you recommend a water based? I am not required to used it, but many painter videos do water based first, then solvent based also, sand & prep, but use the water based, followed by solvent based again. Retired now, but if I had good choices, I would buy a reasonable priced one and solvent based as well. Many use lint-free body supply paper towel with isopropyl alcohol. I just want to use “Best Practices” with a cheaper price tag. This project now is mine. I want to do it correctly. I will spend money for SPI black epoxy but with 5 dead laptops, they come in a couple of years due to limited wallet. I use an iPhone 6 my son sent for WiFi and email/RUclips access. Thanks again for your work!

      @hcr-motorworks  3 года назад

      Thanks for watching! Check out some of my other painting video series for more info on wax a grease removers. If you go to bare metal you definitely want to use BOTH waterborne and solvent based W/G removers and SPI manufactures both of them! Lint free wipes are in the description as well, and then tack rag everything clean before spraying 3 coats of epoxy.

    @GregariousAntithesis 3 года назад +1

    Spot on with everything but one thing, why didn’t you sand blast or have it sand blasted after removal of undercoating? Paint sticks to sand blasted metal like a xhemical bond after sand blasting. Not only that it would have saved you so many hours if prep work and left you a better base for the primer. How long did you wait between primer and bedliner application? Are you going to put paint over primer in areas you taped over? Primer is a hydroscopic no paint it will create rust under the primer.

    So you didn't have to scuff the epoxy before applying the Raptor Liner? Is it still adhering pretty well?

    • @hcr-motorworks
      @hcr-motorworks  3 года назад +2

      I sprayed 3 coats of epoxy with 1hr between coats and then let dry overnight before spraying the 3 coats of raptor liner giving 1hr between coats. I did not scuff the epoxy before the raptor liner. The chemical adhesion that takes place while the epoxy is fresh and then cures is actually stronger than mechanical adhesion you would get from letting the epoxy cure for a week and then scuffing.

      If you've never painted anything with an hvlp spray gun before the undercarriage is a great first project to hone your skills on before moving on to the body work that everyone will 'see'.
      The flat sections you'll want a wide fan, when you paint the corners and tight sections youll need to reduce the fan down quite a bit, adjusting both the fluid needle AND the airpressure to get the results your expecting. Its always easier to add paint till it sprays wet instead of having to sand out massive runs!

Reset the air pressure to hit 20-25psi (depending on what gun your using) when the airside of the trigger is depressed. After the fan size and pressure are set your going to want to turn the the fluid needle in all the way and back out until your getting a nice wet coat. If you find you can move faster and the paint isn't coming out quick enough then you can add another 1/4 to 1/2 turn out for more fluid. If your getting runs and stuff then you need to turn your fluid back in. Just wet is what your looking for. I would hit the corners first with at least 2-3 coats (1hr between coats) and then set the gun up for the wide fan (all the way open on fan, reset pressure again back to 20-25 and then set fluid) for the rest of the undercarriage and spray 2-3 coats on the whole underside covering up the overspray from the corners. This way the whole underside will have a nice uniform wet coat in the end. If you hit the corners last your going to see overspray and a dry line on ever corner.

The only other thing that would be 'better' would be taking it to the professionals and getting it linex'd or the like if you wanted a really thick build undercoating or something. But in my opinion, raptor liner provides adequate build and protection for undercoating without the need to hire it out. Its a fun project but completely is reliant on proper prep in each and every step for good results.

Once your done with all of that then you can just go back over everything with the nylon cup brush or a DA sander and 80grit and hit everything again before wax and grease remover and epoxy primer. I would section it up into tasks instead of sections of the car. Strip, sand, clean, clean again, clean more, tack rag, epoxy, raptor.

      On the Raptor Liner the first two coats are thick and fairly runny...think like spraying tar basically. There's a lot of unevenness with these types of products but you have to get the build thick enough so its effective in protecting the surface. The texture coat is to give it an even roughness and uniform coat on top of the thick layers and make it look better. All you have to do is up the pressure and double the spraying distance and do long uniform sweeps with it on the 3rd or final coat.

      Thats really tough to answer.

    • @hcr-motorworks
      @hcr-motorworks  3 года назад

      Ehh, that's a loaded question but to sum it up yes any 'polyurethane epoxy primer' No single part or 1k products, only use a 2k epoxy or something that comes with an activator and you should be good...lol I'm sure there's a ton of back and forth that people will get into with 'compatibility' issues or potential issues from mixing and matching products from different suppliers but for what its worth I have NEVER used UPOL primers, not saying its bad or wont work but I ONLY recommend two companies for paint products and that's
      southern polyurethanes inc - www.southernpolyurethanes.com/
      Or TAMCO paints - tamcopaint.com/
      Paint and body is one of those segments of the industry that there's like some secret code and tribal knowledge and the big boys don't share information willingly so I narrowed my purchases to the two companies that I believe that go above and beyond and completely out of their way to spread information to the hobbyist, enthusiasts , home builder. That's something you will not get from any other name brand big wig corporation. Tamco and SPI have literally built their business around helping the one man shop and I can't say enough good things about them.

    Hi. Do you think Upol Raptor is better than regular blackson? Thank you

    • @hcr-motorworks
      @hcr-motorworks  4 года назад

      I'd say that if your going to use something other than raptor liner it needs to come in a two-part system. A base and a catalyst, or activator of some kind. Anything that comes in a tub, bucket, pail, container etc that is one part or "ready to spray" right off the store shelf is not going to work near as good as the raptor liner.
      Thanks for watching!

      @@watai My advice would be to do exactly what i did my previous videos if you want it to last a lifetime. Strip to bare metal, clean, clean clean, and when your tired of cleaning the bare metal, clean some more. Then lay down some good two part epoxy primer (hands down Southern poly urethanes is the best stuff for the price and home shop environment) then Use a quality seam sealer (brush able or tube kind) and then Lay down another coat of epoxy once that has cured. Then and only then are you ready to add the raptor liner on the new and clean epoxy primer. Doing it this way and adhering to all the steps along the way will surely lead to a successful outcome that will last many decades. My earlier videos on the undercarriage lay out everything in detail. ENJOY!

      @hcr-motorworks  3 года назад +2

      @@AdrianMontana I apply the 2-3 coats of epoxy to the prepped bare metal and let that dry overnight. Next day I do the seam sealer and let that dry up overnight, day 3 I throw another coat of epoxy over the seam sealer and give it another overnight drying cycle and then on day 4 do the raptor liner WITHOUT scuffing the epoxy primer. With SPI at least, as long as your within the 7 day curing window you can topcoat without scuffing. Anything outside the 7 day window your going to have to hit it with a marron scuff pad at the very least before any additional epoxy coats or top coats are applied.
