    I’ve done quite a few cars wet with medium crushed glass for body shops, never dry though as it heats up the metal too much. If the panels aren’t on the vehicle you have to be extremely careful because there’s isn’t any structure to them and can easily cause warpage. Also I generally won’t blast the interior of panels at all, too much risk. With the proper stand off and angle wet you shouldn’t have any issues. I’ve never had any complaints from any of the body shops that I’ve done work for 🤷‍♂️. Great video‼️

    • @SYLVESTERSCUSTOMS

      Thanks! Yep it’s all in what the customer wants or expects. When it comes to at least 95+% of Bodyshop’s they don’t look at this from the perspective of a metal finisher or coach builders aspect that’s why you don’t hear about these issues. The point I wanted to make in the video was techniques matter and to some any blasting regardless of wet or dry is warping if it’s pitting the metal.

Of course if an inexperienced operator without proper technique is blasting you can 100% warp the living hell out of those panels‼️

    By far best video about this problem on youtube period!!i 23 years ago in our shop we had decently preserved Opel that was about 50 years old at that moment.Car was sent to sand blaster who was and probably still is ignorant fool.It is pointless to say that he destroyed car.I spend days traying to strait damn thing,hammer and dolly ,torch and water,spotter...all in vein!It took about 90 kg all sort of material to make him look nice.And it was round little car "OLIMPIA".AFTER THAT NEVER AGAIN!If it is necessery only inner structure,door yambs....and it is sprayed with rattle can and i'm standing 6 feet behind sandblaster watching every his move like a hawk(ready to kill him).Paint stripper+light sanding with palm random orbital sander will do job just fine.I saw a perfect hood from 70's Cadillac at my colleague shop that was stripped with dry ice and they warped it,how i don't know?

    When i blasted back in the day i could do a whole car with no warpage but it took me two cars to learn how to do it with no damage.
    Luckily the damage after blasting revealed that the panels should be replaced installed of repaired.
    The technique for blasting without damage is low pressure distance and angle of attack.
    Most people just go at it.
    Very good video.

      The warpage we are referring to you cannot feel or see unless you were to block it with a hard block but any blasting that is abrasive is warping. Those techniques help but it’s still warping to a small degree

    I polish the metal after and I check my metal with a block before priming

    This is one of the most informative videos I have ever seen on sandblasting. I have always wanted to do a whole car sand blast with my 1980 camaro but I have heard that after sandblasting the grit gets stuck in all the crevices and then after painting it acts like sandpaper and grinds into the meal exposing raw metal to the elements and then starts rusting. Is this true? What are the issues with a whole car sandblast? I wished I lived in southern California.

I install a lot of fiberglass kits on classic Mustangs and I know first hand how much fiberglass moves but can it be prevented with metal?

    Great video - intelligent presentation. I have for years been cautioning people re blasting. And also staying away from the term "sand blasting" -- NOBODY should be using sand and if they are - tell them to FU-K OFF and not touch your vehicle etc. Abrasive blasting (HA - NOT with sand) can have its place on SOME areas - bur be CAREFUL where you use it - and yes - there are good abrasive blasters and FU-KWITS that should not be let near your car etc. Me - I prefer dipping a shell, and sometimes, spot abrasive blasting - but ONLY on areas that I have no other option. 'Horses for courses' - sometimes. CHEERS from AUSTRALIA.

    Hes blasting at to direct of an angle. Blasters need to learn about impingement angle. I fill in the holes on the underside of bonnets and boots with 2 layers of blast tape so I can blast the frame to stop hitting the inner skin. The demo with the tape was a good way to demonstrate how easy it is to damage. Use the blaster to on a more level angle of about 15° or less so the media is used to basically sand it or wear it away rather than smashing it from above. You'll end up with a not so aggressive profile too. All in all good demonstration and information. Garnet and aluminium oxide works best to remove paint and rust in my opinion.

      @Buddyyouwantoutside impingement angle is the degree of angle the blast nozzle is aimed at the job and media will hit it. The closer to 90° the more aggressive the blasting will be and the peeningeffect will happen. The lower the angle it won't be as aggressive but it abrades it away so to speak like sanding. It's more gentle and takes a little longer. I believe the in my experience that the air flowing over the job keeps it a bit cooler too. Hope that explains it a bit

My opinion, the down side to dipping is the amount of prep work and undercoating every inch of bare metal because the dipping is so thorough. I think the point of this particular video was to demonstrate the potential damage from blasting and to make a stronger argument towards dipping

    Sandblaster pulsating was the problem. Also when sandblasting you need to blast at an angle. This is why wet blasting is better. The water keeps the metal cool thus preventing warpage. Crushed glass is also the best medium not beach sand.

    If your doing a test, how about a real comparison to other media. Plastic media leaves the same finish that the original part started out as, no profile to the metal. Also will remove powdercoating. Using a much lower pressure at the nozzel, We used to get about 1 sq ft of paint removal per minute using plastic at 30 psi, 1/2 inch nozzel, 800 cfm compressor. Lot of volume, no pressure.

    Also, I saw the temp gun and thought ok...but while sanding never saw a temp gun.

The bigger the particle, the more that it will stretch it’s that simple. We even talk about how the pressure, angle, distance all play a part.

    @michaelsatellite9881 Před rokem +1

    Great video but please stop calling it sandblasting. It’s media blasting which can be many different types including: sand, glass, soda, plastic, coal slag, and others. Your spot on by saying it’s the peening effect that warps the metal. More so than any heat induced. Heck a black car on a hot sunny day can see panel temps get up to 200°. Any media that is harder than the base metal can and usually does cause warpage. I prefer plastic media blasting myself mainly because I have no one near that can acid dip, it’s cost prohibitive and I am set up to do PBM myself. It’s gentle enough I have done large low crown panels and it has left the acid etched USS logo that was on the steel before it was stamped. But it doesn’t touch rust or leave a tooth for epoxy. Most of the cars I blast are paint jobs that I’m doing myself and I have never found that it has warped a panel, yet….

    • @SYLVESTERSCUSTOMS
      @SYLVESTERSCUSTOMS  Před rokem

      You get the idea call it what you want. Yep sunny days get panel temps of 200 degrees but they also get heated evenly and cool evenly expansion and contraction vary drastically when performed unevenly across a panel. Plastic media is what I used looong ago and yes that’s the hot ticket! 👍🏻👍🏻

    Sand blast definitely causes damage to your car. I have worked in a restoration shop and worked on hundred of cars that have been sandblasted. The sandblasters say that they don’t cause damage because they are not body and paint guys, they just don’t know. Not only that they get dinged up because they are stacked, moved, handled, and stored in their shop for weeks to months they get all beat up there too. I had a 72 Camaro blasted that my dad bought off the showroom floor new. The body work should have been easy considering the car was all original and factory straight. When I got it back I had to put 10x the body work into it than expected.
