View Full Version : Sandblasting Primer Question
07-08-2007, 07:16 PM
I'm about to get started sandblasting my 70 mustang convertible and will have limited time to move it outside on a rotisserie. I guess what I'm saying is I'll probably have to do it in sections.
What would you all recommend to treat the bare metal? Are there any good spray can primers that I could use? I like what I've read about Picklex, but not sure if that's a good option when it's time to go back and re-cover with primer?

I've left "Covered" sheet metal outside that was treated with Picklex-20 and got no rusting. Flash of otherwise. Even after raining.
I've also left parts outside that I treated with Picklex-20 the coated with Master Series Silver Primer (http://www.masterseriesct.com/) uncovered and haven't gotten any rust yet (one month)
Primers for the most part are made to be top coated, so their ability to stand up to the elements such as dirt, pollen, and the host of other stuff wafting around in the air is very limited.
Any coating (primer) you put on there will need to be cleaned really well and sanded then re-primed before you can go on with the painting though.
I would look into getting a big old tarp from someplace (one that is moisture resistant) to cover things up. If you can minimized the exposure to direct moisture your half way there on the rust part.

I did my car in sections also. There is just too much to get in one day with a home blaster. I used picklex and top coated when I could. If you are moving back inside, there is nothing to worry about with the picklex. I've got a pair of fenders I did in feb. of 06, still no rust. Regards Ron

Just looked at the photos of your '57.... Nice work!
I'm doing a '57 2dr Hardtop for a customer now and have installed disc brakes on it...I'm in the middle of serious metal replacement now, front floors, right quarter, inner & outer rockers, and a bunch of other small metal parts.
After hearing all the good things about PickelX I'm gonna have to try some.......

I'll be moving it back inside after the blasting sessions.
Sounds Picklex is the way to go? How much prep is needed to prime over the picklex?

Hit it with a red scuff pad and go.
Just don't put an etch primer over it. They won't play well together.

Can Picklex be used as a permanent protectant for bare metal parts on cars? Or is there another solution as far as a permanent clear coating for things like that?

It is not as permanent protectant. If it gets wet it washes off and will rust.
But I've got pieces in the garage that have been treated since back when it was ras-o-nil that still look like the day I did them.
How long ago was that folks?

56Ford, Thanks for the kind words. I just wish I had half the talent and knowledge as some of you guys here.
Funny you should mention sheet metal. I am currently removing the right hand inner and outer rockers now and have a couple issues with dismantling the area under the A-pillar. It's difficult doing this stuff for the first time. The bright side is the left side should go easier after I learn what to do or in some cases what not to do.
You'll like the way the picklex works. When you are ready to prime just scuff the picklex and shoot your epoxy. Regards Ron
