Hot Rods What to use in a sand blaster?

Heres the tail gate. I don't think I can sand it off because the knuckle head sprayed the matted paint on really thick. Thats why i thought the sand blaster was the way to go..Thanks Bruce.

 

Bruce: Something to be aware of.....if you don't remove the lock assemblies, they will have sand in them, almost no matter what you do to avoid it. Been there and done that. You should consider taping heavy plastic over them and just use stripper up next to them. You may get by duct taping over them but leave a good margin around them.

 

Thanks Tim. I am only going to be doing the edges on the tail gate and doors.I think the paint I put on the outside of the car 12 years ago will sand down easy. Thanks Bruce.

 

If you don't strip that car down to the bare shell, you will be vacuuming sand out of everything for years. I promise.

 

Why not just buy the harbor freight soda blast converter? That's what I did, and it works really well.

I've only ever used Garnet.
Maybe you guys call it something different, as no ones mentioned it.

 

Lost boy.That's the way I should of gone, but never used one before.Thanks Bruce.

 

I had never used one either. I too use garnet. However I had a cylinder head on my corvair get visually completely destroyed from mouse urine. The fins looked like they were all welded together. The great thing about the soda is the cleanup. When you're done, just hose it off of everything it gets on. It's not as abrasive as sand or even glass bead, so to me it seemed like it took more work. Again, the cleanup is what's great. Especially for you with the locks and hinges.

 

Lostboy.Thanks for the information.Have a GREAT day.Bruce.

 

Bruce the more I think about it (dangerous I know) why not try a cup wire brush on a drill or die grinder? I believe that would bust through that stuff pretty well. Second are you sure that it's paint the fella sprayed on there? I've seen folks spray undercoating on and it flakes like that with no prep work. Joe

 

Joe, you might be right on that.I may try hand sanding it 1 st.Thanks Bruce.

 

Harbor Freight also sells #8 Glass Bead for use in blasters

 

I use Black Diamond fine or extra fine blasting media from Tractor Supply Co.
It's about 80 grit and fairly aggressive. $8 per 50 lb bag but 1 bag will do the work of 3 bags of play sand. Luv that stuff!

 

Looks like those jambs were painted without the original paint being sanded at all. The first thing I would use would be compressed air or maybe even a pressure washer. You may be surprised at how much of that paint will blow right off. Wire wheel is also a good suggestion but you will probably end up blasting a lot of edges anyway. I have wetsanded messes like that off by hand before in the past (320 grit followed by 360 grit) and it's not much fun, but it will avoid the issues with sand in the latches, hinges and interior. That sand will get everywhere you don't mask off, and even a few that you do.

 

Whtbaron, I tried the sand blaster on 1 door jam and I am not going that way .Every ones right sand every where.I tried the compressed air some came off the rest didn't. I might have to go with the wire brush deal and hand sand the rest . Question is why did the guy do that? .Thats the original color he painted over and that's the color I am going back to on the whole car. Thanks.Bruce.

 

Bruce no one can answer the why, but the person that sprayed it on there. We have all done things and then said "What The Hell Was I Thinkin?" Sounds like you have a plan good luck! Joe

 

Joe I did like you said .I picked up a wire brush for my drill .I will start with that and see how it goes.Thanks Bruce.

 

Sand doesn't cause cancer to play with it, it causes cancer when you breathe it into your lungs. The fine particles of silicon cause fibrotic changes in the lung tissue (silicosis) which can lead to an increased risk of lung cancer. Actually, any fine particulate matter is not good to breathe into your lungs..\

 

you might try dow oven cleaner. We used to use it to take sign paint off of truck doors. not ass aggressive as paint remover will leave the harder original finish.

 

5window, I re read the sand bag and you are right. Thanks for the information. Bruce.

 

Always check the max speed rating for the wire brush before chucking it into a die grinder. They spin way faster than a drill motor and can start throwing the wires from the brush instantly. Been there, done that.... Always wear eye protection when using a wire brush of any kind.

Me? I like the baking soda blast method. Wash it off and you're good to go.
Bruce....keep us posted on what works best for you and takes good care of your lungs.
You'll have a lot of followers learning by your example.

 

Man, I think I'd try a rub down with lacquer thinner and a rag first, it might just wipe right off...

 

Phoneman.I never thought of that .I used that when I pulled the bad motor out of my 56 buick station wagon and I sprayed down the engine cradle with oven cleaner and it did a great job, Thanks. A lot of good ideas from everyone.Thanks Bruce.

 

Thanks Ed,.I have the goggles, long sleve shirt, gloves, and resperator. All to clean some knuckle heads screw up.lol.Bruce.

 

2 many projects.I may take a shot at it today or tomorrow.Bruce.

 

Monkeysmooks, I tried that aready but no luck.I will keep you all posted what works.Thanks Bruce.

 

Well I tried oven cleaner but it didn't even make a dent in it. So I went with the wire brush and the drill. It seem to work real good at least now you can see the blue again. Heres a before and after picture of 1 door I did today.Bruce.

 

Heres after.Bruce.

 

Lookin much better Bruce! How long that door take ya? Now you might try and rub it down with reducer or lacquer thinner. That might take off what's left. Try a small spot to see if it lifts the original paint. Joe
