DIY to Professional Painter in 8 easy steps
DIY to Professional Painter in 8 Easy Steps
By Mac’s Custom Haus — Preserving History, One Restoration at a Time
If you’ve ever looked at a freshly restored classic or a perfectly refinished modern car and wondered, “How do professionals get paint that slick?” — this guide is for you.
At Mac’s Custom Haus, we take vehicles from raw metal to glass-smooth, show-ready finishes every day. Whether you’re a DIY painter stepping up your game or simply curious about the professional process, here’s the exact 8-step blueprint we use to transform vehicles with industry-level quality.
1. Take the Vehicle to Bare Metal (Rust Repair Included)
Everything starts with a clean foundation. Stripping the vehicle down to bare metal removes old paint, fillers, contaminants, and hidden damage.
If rust is present, this is where the repair happens — cutting out cancer, welding in fresh metal, and ensuring the surface is structurally sound.
A flawless paint job can only sit on a flawless foundation.
2. Acid Etch the Vehicle
Bare metal begins to oxidize almost immediately. Acid etch creates a chemical bond with the metal, killing surface contamination and improving adhesion.
This step ensures your epoxy primer grabs the metal correctly and prevents corrosion from creeping in down the road.
3. Epoxy Prime & Begin Bodywork
Epoxy primer is the barrier coat that seals your metal and creates a stable base for bodywork.
At Mac’s Custom Haus, we always perform bodywork above epoxy — never on raw metal — to avoid moisture issues and ensure long-term durability.
This is where dents, waves, and imperfections start to disappear.
4. Epoxy Prime Over Bodywork (Lock In Repairs)
Once the bodywork is shaped, we epoxy prime again.
This “lock-in” coat seals all repairs, prevents moisture absorption, and prepares the vehicle for a perfectly uniform surface before high build.
Think of it as adding armor over everything you just corrected.
5. High Build Primer Application
High build primer is the thick primer that allows us to refine the shape of the panels.
This step builds up enough surface for blocking, leveling, and achieving that perfectly straight look that separates DIY paint jobs from professional ones.
6. Block Sanding (180–320 Grit) + 400 Wet Sand
This is where true craftsmanship shows.
We block the car until every panel is flat, true, and wave-free.
Starting with 180–320 dry creates the shape, and 400 wet sanding refines it into a paint-ready surface.
This step takes time — but it’s the soul of a show-quality job.
7. Epoxy Sealer, Basecoat, and Clearcoat
Before color, we apply an epoxy sealer for maximum adhesion and uniform color holdout.
Then comes your selected basecoat and a high-gloss clearcoat to protect the finish and bring your color to life.
This is the moment the whole vision starts to pop.
8. Wet Sand & Buff to Perfection
Even the best clearcoat has a bit of texture.
Wet sanding levels the surface, and buffing brings out a deep, mirror-like shine.
This final polish is what gives that “fresh out of SEMA” look — the kind of reflection you can shave in.
