It's Christmas and I'm sandblasting

[Joe Flanagan]

Yes, believe it or not. I got an early start. I'm working on the channel around the trunk. Bad rust there. It's that hard black stuff that is deep in the pitted metal. But anyway, it's a sure sign I've found my calling. Christmas morning and the sand is flying. Can you get punished for this?

Christmas morning and the sand is flying. Can you get punished for this?

Joe;

As punishment you must now sit out the next 3 postings:D

Sounds like you are making the best of a day off.

The only way it could be any better is if you were sandblasting my stuff .

Merry Christmas Joe.

Man, I envy YOU! All I get to do today is go to my wife's relatives and listen to them talk on and on about that silly game.........you know, the one with the funny little pointy ball. I'd much rather be working on my Plymouth. Good job!

Joe I can relate to playing with the car, I was already out side in the shop with my 47, even started it and drove out of the garage, and it is only 12 above here this morning, if I had the supplies/parts, I would be at some job no doubt, much to the wife's concern though.

The black pits, acid wash these, get them treated as best you can. If you are going with epoxy 2k primer, the primer if put on heavy should bite in there and seal the metal up good.

Or you can go with a time proven substrate primer, which is good old fashioned Rustoleum/Tremclad red oxide or grey primer. You can roll it on straight from the can, or spray with a HVLP or conventional spray gun, reducing the primer with Automotive enamel reducer, usually in the neighbourhood of 20 to 30 % reduction. This primer can then be worked over, ie fillers, high build primer, primer surfacer lacquer based primer, 2 k Primers etc. The only qualifier on the alkyd based primer by rustoleum, is it takes upwards of 3 weeks to fully cure, once cured it will sand and take fillers etc, on top of it. I gives a very superior corrision resistance, and the bonus is it's cheap like Borscht, well it used to be cheap.................Rocky

Yeah, I'd like to have someone do this for me. But it's better than doing it on your back UNDER the car. I just tried an experiment. I scrubbed phosphorous acid into the rusty surface and let it sit for a few minutes. Then I hit it with the blaster and it just disappeared. Maybe I came across a particularly easy stretch, but maybe I'm on to something. I'll keep you all posted. Trying to post pics but my computer keeps telling me the file is too big. I have Jasc Paintshop on my computer and I apparently have to buy extra capacities if I want the ability to resize the file.

Charlie..I feel your pain...there are never sports on TV at my house..so come on over..kick a few tires...

Only feetsball I watch is when Rothelesberger plays. Lisa used to babysit him when he was about 5 years old and I knew his dad well.

Olddaddy,

What's the silly game with the pointy ball?? Inquiring minds need to know!

Rockwood,

Haven't heard the expression 'cheap like Borscht' in many years.....my grandmother used it occasionally, and she didn't say it in English!

Joe. Sounds as if you're having fun. Why don't you try to use PhotoBucket...it's free up to some amount of pics (can't remember their

limit). You can re-size the pics as you put them in......or even after you

get them in. There is one size called "message board" that I normally

use. Even if you pay them for more space, it has been running $25 per

year.....not too bad really.

This is 640 x 480 pixels size for message board.

Rockwood,

What I've been doing is treating the bare metal with a phosphoric acid-based stuff called Picklex 20. Then I'm using a two-part epoxy primer made by PPG. In areas that won't get painted, I'm using a product called Zero Rust, which is reputed to be far superior to POR 15. I used it on the frame and I'll use it on the floor and most likely in this trunk channel I'm working on now. Can't really tell if the phosphoric acid loosens the rust any and makes it easier to blast off. Just seems a bit easier.

By the way, I've posted pictures with photobucket before but it's been so long since I used it they have to send me my password again so I can log on.

Joe..when treating an area with phosphoric.use the propane torch..make sure you have on breathing protection and saftey glasses or at minimum glasses and well vented like outside..you can flash the acid wetted metal with the flame to speed the operation..rust will pop off like pop corn..the metal left will be a clean gray finish..this is very helpful in areas where wire brushing or access is limited..

[Joe Flanagan]

Tim,

I tried this without any luck. The acid bubbled up and turned white but the black stuff just stayed. I was using Mapp gas, if that makes any difference. Do you have to let the acid sit a while and then heat it? 'Cause I didn't do that. I put the stuff on and then tried to heat it right away. Do you have to do multiple applications of acid and just keep the heat on it? Great tip, by the way, I hope I can get it to work.

[Plymouthy Adams]

I use just a plain ole butane torch...and yes Ilet it soak a tad first..

[55 Fargo]

Picklex is reputed to be a great product, although I have not tried it myself, zero-rust is supposedly better than POR 15. For myself, I like Tremclad, chemically much like POR 15, at a fraction of the cost. Sounds like you are doing a bang-up job...................Fred
