Fixing Orange Peel in a Bad DIY Car Paint Job | BWG
Exterior Repair

The paint mistake.

The bad paint job came with the wagon. The orange peel, the body filler, and the mystery repair work underneath are now my problem.

Quick Answers

What the paint recovery has revealed.

Observed when purchased

What was wrong with the paint?

The previous DIY finish had heavy orange-peel texture across the wagon. The hood and roof were the areas that bothered me most.

Work completed

Did sanding remove all the orange peel?

No. Sanding improved the surface, but primer still revealed remaining texture. More leveling work is needed.

Observed after primer

What did the primer show?

It made the remaining uneven texture easier to see. I also sanded through the primer in several places while trying to level the surface.

Previous repair unknown

What is under the roof paint?

I found a substantial amount of old body filler. I do not yet know what damage or previous repair it covers.

Current status

Is the paint fixed?

No. The hood and roof remain in preparation, no finished color coat has been applied, and the mechanical work now has priority.

Repair Snapshot

Not my mistake. Still my problem.

When I bought the wagon, the paint was one of the biggest reasons it was affordable. From a distance, it had the right shape, the right vibe, and enough charm to make me ignore a lot of things.

Up close, the paint was rough. The more I sanded, the more I realized this was not only ugly texture. Old repair work was hiding underneath it.

What I could see

Heavy orange peel: the finish had a bumpy texture across the body.
Bad paint texture: it looked like a rough repaint rather than normal aging alone.
Rough roof and hood: these were the large panels that bothered me most.
More sanding than expected: a quick pass was not going to level the surface.
Old work uncovered

What I found underneath

Old body filler: the roof contains a substantial amount under the paint.
A mystery repair: I do not know what the filler is covering yet.
Primer burn-through: I sanded through the new primer in some areas.
A bigger project: the job became an investigation of old bodywork, not just surface texture.
The Process

Sanding down somebody else's paint job.

Step 01

Start with the orange peel.

The previous paint had heavy texture. That was one of the first visible problems when I got the wagon.

Step 02

Sand more than expected.

I sanded the hood and roof repeatedly. Progress was visible, but the surface kept showing that this would not be a quick cleanup.

Step 03

Apply primer and inspect.

After sanding, I added primer and hoped the surface would look smoother. Instead, the remaining orange peel became easier to see.

Step 04

Sand through the primer.

While trying to level the panels, I burned through the primer in a few places. It was annoying, but it also showed how much work remained.

Step 05

Find the roof filler.

Sanding exposed a lot of old body filler on the roof. I still do not know what is underneath it.

Step 06

Accept the larger job.

This is not just fixing bad paint. It is uncovering previous repair work and deciding how much needs to be corrected before finishing the body.

Step 07

Pause before color.

The body is not ready, and the engine problem now comes first. Spraying color over visible problems would only hide unfinished work again.

This is a project record, not a universal refinishing procedure. Follow the exact abrasive, primer, ventilation, recoat, and protective-equipment instructions for the products being used.

Lessons from this attempt

What I learned

Primer did not hide the prep: it made the remaining problems easier to see.
Orange peel was stubborn: sanding helped, but it did not erase everything.
Body filler changed the job: once it appeared, I needed to understand what it covered.
Stopping was progress: an unfinished surface is better than another layer over unresolved problems.
Current project status

Where it stands

Hood: sanded, primed, and still needs more work.
Roof: more investigation and sanding are needed around the old filler.
Color: no finished color coat has been applied.
Priority: the wagon's low-compression engine problem comes first.

Original BWG videos and project notes

The two embedded videos and the original notes document the sanding, primer, remaining texture, burn-through, roof filler, and unfinished status.

3M Dry Guide Coat

3M's product information explains how guide coat can reveal pinholes, scratches, and uneven filler or primer before top coating.

Rust-Oleum Guide Coat Primer

Rust-Oleum's guidance describes using guide coat to highlight low spots, scratches, pinholes, and other surface imperfections during sanding.

Engine diagnosis and repair archive

The low-compression diagnosis explains why mechanical work now takes priority, while the repair archive connects the wider project.

The evidence labels separate what I photographed and completed from manufacturer guidance and unknown prior bodywork. The condition beneath the roof filler and the final paint outcome remain unresolved.

Still better than yesterday.

The paint is not fixed yet. The roof is hiding something. The primer is already burned through in places. Somehow, learning what not to cover up still counts as progress.
