Prep prior to paint.

[California 72]

Using VHT chassis paint, they say that it doesn’t need primer and understanding the curing process for their paint is more chemical that evaporative, there’s a specific primer needed.

I am watching budget not regardless of the added work but rather because of it.

The primer isn’t inexpensive so I’m following their claims and skipping it. This has created a couple questions.

As far as prep, I’m trying to remove as much rust, both surface and deep. So, as things get cleaned flash rust appears.

Immediately prior to paint, everything will be wiped down with acetone. Is the flash rust able to be covered directly with the Chassis paint.

As far as other, more unreachable places like recessions and creases, I’m brushing on rust converter so, does that require any special prep?

Thanks with your help here as well.

I am using Rust-oleum Rust Reformer on places that are easily accessible, it is both a rust converter and a primer.

On less accessible places I am using Eastwood Internal Frame Coating, it also converts rust and coats it. It comes with both a regular spray nozzle and a flexible tube that has a spray nozzle and allows the inside of enclosed areas to be coated, like the A pillar, the crash frame inside the door, inside the kick panel areas, several nooks and crannies in the fenders and doors, rocker panels, cowl and so on. They both cost more than regular primers, but less than epoxy.

Internal frame coating. That’s what I was trying to think of when I was searching. So it worked good? I’m more curious about coverage at the point. I believe we’re sharp enough to realize you can’t see in some of these spaces so, does it apply well?
I’m messing with the cowling right now and at some point in its life, probably when it was last repainted, they spread a sealer paste and just painted over when cured instead of cleaning and prepping better.
When you start asking the questions, it starts to sink in how much work starts to appear the deeper we look.
Thanks for the info.
