Hi Guys, 

 

             I am aware of "Minus Paint" in SA and Redistrip in NSW but was wondering if there is a similar service anywhere in Brisbane or close by ? 

 

thanks in advance

I would Google dust less blasting in brisbane, if I'm correct that you're wanting the hydroblast a vehicle shell ? Gary.

On a rotiserie, you should be able to blast everywhere in reality mate, if you do get it blasted with garnet ect, just be sure to mask up holes in pillars ect with blast tape before you go there, most of those shops sell blast tape, for about $15 per roll. The water, or dust less hydroblasting is able to do outer panels aswell, without warping the panels. I believe it's usually around $750 to $1,000 more than sandblasting for the whole car.

Thanks for the suggestion Gary!

 

I think I saw something about Envirostrip recently, but have not chased them up as yet.

 

The thing blasting can not do is get in between seams etc when corrosion might be lurking, that's the main thing I'm concerned about with my 38 coupe, there's a few areas where i know it would look great after blasting, but I know there is stuff lurking that I want to resolve long before we get to primer and paint.

Hi Mick
No leads sorry but I did talk to my neighbor about minus paint here in Adelaide. Their process strips all paint and filler including any seam sealer. There is a separate bath required for the rust removal which I believe they farm out. It would then be necessary to get on to the hidden areas with a pressure washer to clean off the dissolved rust. All seams will need to be resealed of course. Then there are the stories of acid leaching out through the finished paint after a while. I don’t know how much credence you give these.
Anyway good luck with it.
Cheers
Clay

The dip is acid I believe. It gets into nooks and crannies and stays there and continues to eat away I'm told. Strip the car to a bare shell and take your chances with the blasting of your choice. I didn't because there were no guarantees of no panel warping. So I just went with paint stripper that got it all back to bare metal before epoxy sealing.

I've had shell and panels media blasted, if the guy knows what he is doing there will be no issues, most won't do a bonnet or roof as they are risky. Also its more work but paint strip any panels you are worried about first, then there is far less pressure from the blaster needed to clean it up. 

After getting a guard dipped I wouldn't do anything with a seam in it. After it still had some rust hidden inside back of guard I separated the reinforced bit from it and the seam was still full of some liquid

In regards to "dry" media blasting. Personally i would only be doing that inside the doors, door jams, boot, boot jams, floor pan, dash, inside (not the roof) engine bay, under the wheel arches, window frames and openings. I would manually strip the outside with paint stripper. Obviously the bare metal needs to be epoxy etch primed as soon as possible. Wet blasting you could do the whole shell, i can't comment on the acid stripping as i just haven't seen much of it. Gary.

Stories abound about the problems with dipping.

Just as they do with warpage from blasting.

After doing some research, I would go dipping if I had the bucks.

They start by dipping on an alkaline solution. That softens and removes paint etc.

It is then cleaned and neutralised with water.

Then it gets the phosphoric acid dip, dried and shipped off.

The acid dip follows the normal procedure for the rust convertor that lots of people use these days.

 

I highly doubt the stories of the acid coming out down the track.

If the proper process is followed, everything is dry, and actually neutralised anyway.

 

I would do it myself.

I reckon it gives the best results looking through what I have researched.

Probably the closest would be Albury.

Been a while since I looked at it though.

 

Ive been running it through my brain as something I may even set up myself in the future.

 

Remember. Everywhere the chemicals get t, the neutraliser gets to as well. Water in the first instance.

 

Cheers

 

Rob
