Preping frame for Powdercoat - The 1947 - Present Chevrolet & GMC Truck Message Board Network

GaryM · 11-04-2010, 08:54 PM

So getting ready to tear down my 69 C10 step and want to know what you all do when preping to go and get sandblast and powdercoat done.

I was reading on one of the build pages in the forums that the person nocked out all the old rivits. My guess is that they must replace them with new G8 bolts and hardware. Any thing else that needs to be keep in mind when doing tear down.

Oh I will be doing a build thread also

great question?? why would you take out the Rivets? what are you gaining?

Just make sure you have everything done with your frame before you PC. That's what I remember a friend said when he did his rock crawler frame and needed do more mods after the fact.

One reason for taking out the rivets would be to get to trapped rust under the frame parts (spring hangers, shock mounts etc..) It's a lot of work but worth it in the end. I took out about half of mine, wish I did them all now.

Make sure you take 100 measurements so that you can get it square again when you put it back together. I purchased all of my grade 8 hardware from Tractor Supply, they sell it in bulk...

Also wouldn't hurt to degrease any heavy spots so the sandblaster won't take as long (time=$$)...

Think I will be removing all the rivets on my frame. I have been welding for a living for almost 10 years now so have lots of exp at keeping things squar and true in the end..

Think it would be cheeper when time to blast and PC the frame because no crazy corners to get clean.

are you going to PC it in pieces? whats going to happen when you put it back together and your not metal to metal? I am not trying to sound negative!!! just trying to understand the advantage of getting the rust under the rivets verse the actual intergity of the frame.

I dont see how haveing PC between the frame rails and crossmembers will be an issue if the bolts are tight with locking nuts or washers they should not work free or rub.

If you buy a cross member from CCP they powdercoat them, do they leave the area where it mates to the frame uncoated. you would not think so that is a place where rust can form.

I did a frame for my Typhoon several years ago - prior to having it sandblasted I took it to a professional pressure washing service and had them blast it - I think they charged me $35 and it got 99% of the oil and grease and scale off. Then had it blasted and PC - still looks every bit as glossy 5 years later.
