the welds rust. the tiny pieces of paint on the sfc's that get chipped by rocks will leave rust on the exposed sfc. i'm just wondering if this is an issue, or if spreading rust in the future will be an issue? i've never seen this question come up, but even if you don't inspect your sfc's or don't drive near rocks (ha!) this is at least happening on your sfc welds. what do you guys think about the matter?

 

Rust is only one reason I choose bolt-on SFC, Por-15 is probably what you want to coat the welded areas. JMO

ya, but is it necessary? there are so many out there with rusted welds, is it a big deal for real?

 

If rust doesn't bother you then just leave it, for me it would be a big deal, but that's just me.

 

most people hit the welds w/ rustoleum type paint after welding them

 

ya, i guess i should go back over it with some rustoleum (even though they are still rusting now). the welder did not go over them with rustoleum.

 

You can use a cold galvanizing compound or something like POR-15 (eastwood has a brand of their own)

Check Eastwood--->

Beware their shipping is the suck.

I paid $28.95 for ONE can of Bloxide.

 

Make sure to thoroughly clean the area before applying any paint. Use a sandblaster or a wire wheel and then clean with acetone or something similar.

 

then for best results epoxy prime the areas in question,works much better then the por-15

 

The guys that are giving all this very good advice on rust prevention are in climates where the winters create havoc on exposed metal.

In Austin, the rust you are seeing is surface rust or discoloration. Get a wire brush and clean it off and you will once again see shiney metal. I bought one of those cheap foam paint brushes and some metal, rust inhibiting paint and painted over the areas of exposed metal. It was for cosmetic purposes only, though.
