Beauty is skin deep

Here's what appeared to be a very nicely "restored"
V-81A that I'm shopping out for a customer to repair some (what was supposed to be cosmedic damage),

underneath the slick looking Coke-red & clearcoat is  shoddy workmanship, what caused it? an improperly re-installed drain tube & missing chassis chalking, now he's in for some $$$ in repair work to take care of the rusted out bottom pan & sides as well as the inner tray of the main door.

once repaired, I'm coating the back-side of the tank/liner with Rino-coat ( spray on truck bedliner, basically catalized liquid plastic) also the back or the doorliner (also corroded) and we'll be hitting the chassis bottom tray about 1/4 of the way up to. ( after media blasting) I'll post more pic's as this progresses

Ive seen this one to many times, Thats why you ALWAYS sandblast every square inch of a machine.

I agree, you also have to disassemble it, & get to what lurks beneath...his stage, along with a contant supply of water from the leaking drain tubing, it would have been only a short while before the outer finish would have started to blister.

In this case, my bodyman is going to apply "soda-blasting"
(baking-soda that is, sodiumbicarbonate) this will be less aggressive to the thinned metal, but very thorough to the rust, plus, its fine texture will help get into the seam areas better than sand .

Huh?  He uses dry baking soda instead of sand?

[johnieG]

Yes, it's baking soda, but not as fine as the stuff you use in a cake, it's a little more granular like table sugar in texture, it can be used dry, like conventional media, or wet in a water blast. it's been used sucessfully in the automotive restoration relm for a few years now, they also have a "K-Line" (Potasium chloride) media which is a bit more aggressive, but still will not harm the underlying metal/base,

Here's an  an update of the Vendo V 81a's restoration as it moves along, basically the first "restoration" was strickly cosmetic in nature, as the pictures are showing, none of it (prior resto') addressed any of the rustout showing in the pictures,

I've added a stiffing brace lengthwise down along the rear inside wall, to remedy the "oil-can" effect common on this area. and the new bottom pan has been fitted & tack welded into place, as well as a nice fiberglassing to the outside of the back (also to add stiffness to the is thin area. (this was added  to take care of some panel weakness due to a "dolly-handle" which was removed from the back , actually it appears to have torn out, because this areas metal is thin to begin with)

we also treated the pitted inner chassis with POR rust treatment & POR Topcoat, this stuff is tough! if you work with it, use gloves, because is doesn't come off skin, untill it wears away!  anyway here are the pictures to date...l

Hey thanks for the images and info I'll look into the Rino-Coating stuff when I start taking my machines apart....
You're doing a great job... sould put these images larger in the before after gallery for other to watch and learn from.
Again Thanks for posting

i suppose a lot of you have a shop or send out for sand blasting. I was thinking about purchasing a siphon feed for the garage. After reading this post I know I want one!

If you do this at home, do you use a tarp build a catch?

Is the media reusable or do you spread it through the yard to help with the flowers?

The one below is a Maxus 10.5 cfm @ 90 PSI. Says it give approx 150 minutes of blast per 90 lbs bag of media

Any help would be aprreciated.

Thats sad...Thats what i love about this site you guys take the older machines that people have moved past and rebuild them to better then the new ones!!

I would think twice about doing serious sand blasting in the garage. My dad had a car sandblasted in our garage when I was younger. When we sold the house 5 years later we were still finding sand everywhere and we lived in Ohio. Not something i would advise if your wife isn't understanding. '>

Dave, the holding tank on the sandblasting unit you showed is far to big, and hard to store.  Look for a smaller one, even though you may need to fill it more often.
