Subframe and Suspension paint DIY

Another one that I  went back and forth on, searched, read, called SCR, got quotes for powdercoating, etc.  Finally settled on this because its quick, and relatively cheap and painless. 

I found a local place to sandblast the parts, then found this 2K Epoxy spray that was hella expensive but super convenient.  I followed that with the 2K Aerospray satin black from Eastwood. Both of these products have an inner chamber that gets activated/broken to release hardener.  We'll see how they do.  It took me 3 bottles of the primer and 2 of the satin black to do what you see here.  One coat of each.  There are a few thin spots that I would cover with more satin black if I had another bottle but I'm not going to crack another one and waste most of it.

Covered in Rust and Ziebart and 40 years of dirt, sand, and mung.

Paint booth or Abattoir?

Done.  

 

A few things- I probably should have hung the parts up but I just want to keep things moving and I am trying to avoid trips to the hardware store during Covid Lockdown (I'm working in the ICU with COVID patients and am at this point more worried about transmitting to innocent bystanders than about getting it myself). 

 

The blue stuff is disposable OR drapes.  If you know anyone who can collect this stuff opened and unused (it would otherwise be thrown out) I highly recommend it as dropcloths and help masking.  

 

I didn't paint the steering links as those are newer and in much better shape so I'll just clean those up.  In retrospect I should have done the springs, too, but I'll probably just touch those up as they are also newer.

Nice work.  While powder coating (assuming the applicator is good at his/her job) provides a really nice, durable finish - you can't fix it when it gets dinged up. - you have to take it all off and start over.  I think the route you went is smart with high end primer and epoxy paint.  I did pretty much all of my suspension bits in flat/satin black epoxy paint (VHT Chassis/Roll Bar Paint).  Goes on nicely, very durable and if you need to fix something (ding, run …. whatever).  Easy peasy.

Nice job!  Curious, what was the quote you received to get it all powder coated?

I think the quote was around $400, which isn't all that much, but the guy didn't seem like he had done this kind of job before, and as noted above and elsewhere on the site, powder coating can cause problems.  SCR does museum-quality work that I can't afford...
