I used stripper on my hot rod. Did the whole thing that way. On another project (PU bed) I used a DA and cup wire wheel on a 7" angle grinder. When I did the PU, I got a bigger compressor, 5 true HP 2 stage. That would run the DA full time or close to it.

If/When I do another, I'll use the DA on the flat areas and stripper on the tight curvy spaces. A DA with 80 grit - with the orbit locked out - removes the paint very well.

I repaired, smoothed, primed and painted mine. The toughest part for me was the finish paint. I wasn't pleased with my job so I took it to a body shop and they blocked and re-shot the finish paint. Its nice now.

On the air for blasting... a 5 HP compressor will work fine for small parts, brackets ect. Not so good for a whole car.




Only 80 grit for removing paint? I tried 80 grit with my sander and that didn't do too well. When you say, "orbit locked out" you have it rotating in a complete circle with no wobble?

I was actually thinking about using the stripper on the large flat areas and then blasting the nooks and crannies...

Thanks

For inside like that, I'd try those 3M stripping pads. Might take a few pads but I bet you could strip the outside body in a afternoon. But it is gonna be dusty big time. You are gonna have to make dust anyway if you were to chemical strip because you still have to DA sand it and then your makin even worse dust because it'll have paint striper in it. In side like that I think your best bet is a stripping pad and a DA sander without chemical stripper. Good luck very cool car!
I once rebuilt a straight 6 engine in one of those for a girl in hi school back around 1978.




What sort of 3M stripping pads are you referring to?

That's a pretty good price for stripping a car, but maybe that's because you bring it there. I've heard prices of over $1k, but they come to your house to do it.

What was your point about the weight? Would it be enough added weight to make a difference? Hoping to get the car down to about 2,900# without me in it, so anything I can do to drop more weight is good.

Thanks

Scott




A paint job will weigh about 75-100 pounds when its
all said and done when you talk body filler, primer,
sealer, paint and clear... so that adds up quick
if your talking a race car... I mount a set of casters
on legs with bracing and take the car to them...
I winch it onto my open trailer and drop it off...
if I wanted the mess at my house/shop I'd do it myself
and save the money

I didn't realize it was that heavy, but when you add it all up, it does sound about right.

Yea 80 grit is what I used it worked good for me. The first car I stripped with a D/A was my corvette so I didn't want to get too aggressive being a plastic car. The Norton Magnum 80 grit discs with the D/A and the orbit locked out ( yes spinning in a complete circle)on a metal car took the paint off plenty fast for me. Just take it one panel at a time tape off the windows so you don't scar them while sanding if you're leaving them in. Use a shop vac to suck up the dust not an air hose that will blow it all around your garage. Wear a dust mask.....

And with all the ...This was the answer I was thinking of also...Not sure if the pics are'nt showing issues we can't see but I'd scuff and shoot right over the original paint...Even if there's some minor bodywork to be done you won't beat the adhesion of the original paint for a great starting point...The car surely is'nt a clapped out rustbucket that some are blasting away on..

Yes those work good for stripping paint.

To OP I would not strip it until your gonna repaint, if that's what your gonna do. Don't strip it and then leave it sit and hope it don't rust because it will.

If your gonna ruin it with flat black paint, then don't waste your time stripping it.
Did you know that black cars take terrible pictures at the track because the track is black in the back ground and the car doesn't not pop in pictures. imo

i agree with just scuffing and shooting it if your going flat black. no point spending time on the body when the paint isnt even going to show it off.

being a media blaster who specializes in automotive stuff, i would abrasive blast everything but the outside panels with glass (sand belongs at the beach, not on your car) the rest i would soda or walnut blast depending on your budget.
on a job like that underhood, underside, interior, jambs, trunk and body would be $1000-1300 underhood and outside would be $750-ish

might want to look locally for a blaster its money well spent most of the time

I don't do it either for anything less than 100 buck an hour and even at that I'm not getting rich.
I have to pay for media, fuel for the compressor and wear and tear on the compressor and equipment(hoses and nozzles). 100 bucks an hour is cheap.
65 dollars an hour is crazy.

We have not used walnuts yet, but silica, black beauty,there is 2 types of black beauty, and we use the 2 different types of the media (without looking at the boxes) I don't remember.
It really doesn't take long if you stay on the job, run about 45-50 mins on a tank , not anything hard work about it, have suit on and outside air .
The most anyone charges here for blast work is $100 hr , and he don't run much cause no-one can afford that much, our shop is set at $75 hr,for blasting.
our main work is with the black beauty stuff,, a few intake jobs as they come.
black beauty run 7cents @ # silca is alittle more last we got @15? cents #. so pretty cheap. and you guys get to rerun the stuff as much as 2 times , some make 3 runs on the same media? Our shop rate is 40
@hr.I make $15 hr, your'e getting $100 or more Hr to run your blaster, and you say you don't make money?

If that is original paint, I agree.
No reason whatsoever to strip it. Sand it down, seal/prime it and put on surfacer.

If it's not original, then remove the paint down to bare metal. You have no idea what someone else has done or what corners were cut.

i dont use black beauty or any other silicate based media so my cost is more. i also do not reuse my media. Your blasting a challenger, (outside sheetmetal?) and your going to use that slag on it? you ever done 1970's mopar sheetmetal with anything that abrasive before? i am curious to hear about the results, i know what mine would be.

at $100 for the abrasive blasting i have taken alot of commercial work away from my $70/hr sillica based competition so i am doing something right.

nope wont use black beauty on it we will use what ever the customer wants , I have used it tho on other jobs as requested, the #2 beauty is alot better use than some media ,
as for being 1970 metal, we use it on 1920-and up tractor tin with great results! some of the tractors we have done are 'expo' quality! and award winning for paint and restoration work !
depending on the nozzel used we can cut a 8" path , or as small as 2" path. alot does depend on pressure and style of operator, and type of media used
yes we do alot of commercial blasting,
Not saying anyone is doing bad, and I don't recomend that every car be media blasted, as with this op , it appears his car is a very nice car to start with , and with just a small amount of sanding -repair- and primer -repaint , he will far ahead of lot projects.
any kind of blasting material has a chance that could produce anything of issue , be it silica that can imbed itself in the metal and return at anytime after new paint is applied to the heating of panels to the point of warp can and does happen.
as for price of blasting , that goes by area and local other companies in the area, around here there are several, so not like there is anyone with a lock on the service.
after all it is in pride of doing the best job possiable for the customer , that is job 1 !
