    Amazing video. I worked under a professional for a short time years ago and your video reminded me of the things I forgot. Very comprehensive and well made. Thanks for taking the time. Much appreciated.

    Now 2022, it’s been 11 years since this video aired. The worst blocking issue it almost two fold on the same vehicle. This is my 67 C10 truck. #1 area hard to block is the center of the front hood. It has a peak, reverse crown and convex areas that change from from to rear. I used a contour gauge to form a block from a hood in the package my son bought. Once drawn, 32 grit on die grinder created the front, but it get smaller at the rear. Make a second one and keep going. I was exhausted until I got into the reverse crown that changes to larger toward the rear as you progress down the side, front to rear. Having built a block that fits helps duplicate both sides so close you could not tell.
    As you mentioned, but black epoxy, covered the a gray high build, let’s you know once you pass thru primer into a sealer into a different color.
    Thanks.

    There are wet sanding and dry sanding methods. Either can be used and both are effective. And you are correct, you want to final sand before painting with 400 to 600 grit sandpaper before painting. Thanks for watching!

      Donnie Smith. Hello! I have a question if I may. I am wet sanding 2K primer with 400 and I hit metal on some edges. My question is Do I have to put primer again on that expoused metal and if I do what primer? 2K or epoxy primer? Remember im wet sanding for paint, thanks.👍🇺🇸

    Thank you so much for the tips. I'm restoring a 1959 Glastron Fiberglass boat and just primed the hull and wasn't exactly sure what to do next to prep for the finish coat. This video was exactly what I need to see.

    • @CarAddictGarage
      @CarAddictGarage  8 років тому +1

      I am going to start a boat project soon. I would use guide coat and final sand the boat with 400 grit sandpaper. Then you should be ready to paint. You can finish it like a car. You can also use a gel coat, which is a little thicker, but does not have the gloss level as automotive base and clear. This lesson will help you out with the prep process. www.collisionblast.com/paint-prep/ Thanks for watching.

    Leaving it masked off is fine except for when actually using "some" of the extra extra high build Polyester, Epoxy Primers. As the build that it creates will/can leave such a hard/built up edge/line depending on the "masked situation." Plus, applying different stages of primer over the same tape/paper "can" make it a miserable bytch to pull off/unmask. Also? Leaving the used paper can cause LOTTA extra dust/debris that just ends up in your primer being shot, and on some primers? Cause it to "fuzz up" more and ya spend MORE time sanding the stuff vs just using more tape/paper/painters plastic to remask....Just my 2 centavos. Keep a GRINDIN! 👍

I just did a F250 for a guy and did a lot of work to it, if it where me the truck wasn't worth the money it took to fix what I fixed

  • @1JoTyler

    Great video and i gueas the best advise i could give is to wet the whole car before paint , that will show you any imperfections when looking down the panels. If you are having a hard time getting the lines out use a da file softly but quickly. An older friend helped me with that years ago and the black car came out slick. Keep up the great work!

  • @TheMrmmkkpro
    @TheMrmmkkpro 4 роки тому

    I see why it's so expensive to get a good paint job. I'm a good mechanic but body work and paint is an art in itself. Working on a 1990 ZR-1 and it has so many curves on it. It's white and I'm keeping it white, all the factory paint has like little bumps/bubbles and some spyder cracks. I think I have bit off more than I can chew. It takes a lot of patience and a certain feel. Thanks for your videos, they really help a novice like me a lot. 👍👍

    Thank you for the good video. Restoring my 1971 Lemans Sport convertible, and just cannot afford to pay the 10-15 grand I've been quoted by several for a good street paint presentation. Most shops seem to think concours or nothing. I found a mobile soda blasting company that will do soda blast at my garage. The car is relatively clean of rust with some typical body dings and some wavy panels. I figure if I can do the bodywork and prep, I can save a bundle to then have it professionally painted. Again, thank you.

      Donnie Smith. Hello! What should I do if I did the body work and of course I thought my body work was really good on a hood but after using Eastwood contour primer I used 320 and some metal showed up. Now im confused. Should I spray some epoxy primer in that small area then sanded down and spray 2K primer? Thanks and love the videos, thanks for the time and effort you put into them👍.

    • @constitutionalrepublican1611
      @constitutionalrepublican1611 6 років тому

      MrElPoderozo1 definitely use the 2kp- depending on the color of the car you may want to hide the work by spraying a silver paint in that area. Its a 90's trick me and some friends came up with for ppg/matrix systems.
      Good luck

    • @MrElPoderozo1
      @MrElPoderozo1 6 років тому +1

      Liutenant General. Thank you for answering me. So it doesn't matter if it is showing some expoused metal as I was feathering down the Eastwood Contour primer?
      I can spray the Eastwood 2K primer over the metal and it should be ok? Thanks again for your time 👍

    FINALLY, an instructional video that explains everything I was wanting to know about prepping, priming, blocking and using guide coat!!! Subscribed and thankyou for also considering the people on a budget! I already threw a lot of money out on the rustoleum paint roller technique only to go back to step one again because I either didn't prep right or because crutial information about prepping were left out. Lots of wasted sandpaper, paint and disappointment. I wont be using a spray gun but the techniques you described will help a lot

      Hi Donny, I asked you a question on another video and would be grateful if could tell me what the main differences are between "sandable" primer and filler primer is? Also is it okay to spot spray areas with bare metal with etch primer and then go over the whole panel with the sandable or surfacer? Thankyou.

    • @ArturB993
      @ArturB993 8 років тому

      Also the etch dries a little smooth, worried it won't have enough adhesion.

  • @darkwillow57
    @darkwillow57 3 роки тому

    If you're blocking and you get down to bare metal you can't block that area anymore. Because your sandpaper won't sand the metal but will sand everything around it. So the metal will end up being high if you keep blocking there. Just as I was making this comment I came to the point in the video where he basically said the same thing. Oh well. Thanks for the video it was easy to follow and informative.

    Starting with 320 grit ensures that the paper will roll into and over imperfections.
    START WITH COURSE PAPER 80-150. Course paper properly cuts the highs and levels to the lows. Too fine a paper (even with a block) will often roll over the imperfection.

    Donnie I love your videos, you provide with so much information that could be the difference between an ok job and a great finish. I have a question though, once you block sand and you end up with low spots, do I just try to level them those spot up with body filler again or glaze putty? or should I simply keep block sanding till everything is leveled?.
