Does the glass have a dark visor tint?
A slight variation is visible near the top of the windshield, but it appears uniform once installed.

Glass Installation Questions
Installing your glass? Start with our flush mount glass install guide and install tips for test-fitting, prep, and a clean, weatherproof seal.
Can I install it myself?
We recommend professional installation due to the complexity.
What if I still want to install it myself?
Professional installation is highly recommended; we do not provide DIY instructions.
Do I need trim to cover the gap?
Not necessary. Use weatherproof silicone for a seamless finish, or you can source your own trim.
What comes with a set of Fesler Flush Mount Glass?
One laminated glass windshield, one tempered glass rear window, and a crate.
Do I need to modify my car for installation?
No modifications are needed for OE openings.
How do I test fit the glass?
A detailed step-by-step guide is available on our website.
Why doesn't my glass fit perfectly?
If any modifications have been made to the body of your car, you run the risk of needing to do work to make the glass fit seamlessly. Any new panels, welding, or modifications can cause warpage or misalignment of panels, making the opening less than from the factory. We recommend test fitting the glass during the paint and body stage to ensure a seamless fit.
Can I modify the glass to fit?
Not recommended.
What if I break my glass during installation?
No warranty for breakage during installation, but contact us for a possible discount on replacements.
Can I install your glass on a painted car?
Yes, but be cautious of potential scratches.
Is the gap at the bottom of my A-pillar on a Camaro normal?
Yes, it was previously covered by trim.
Should I remove OE trim clips and tabs?
We recommend removing them.
Interior & Fiberglass Parts
Dashes, panels, A-pillars, and other hand-laid fiberglass parts ship raw and are finished to your specific car. Here is what to plan for.
Installing an interior part? See our interior parts install guide for fitment and finishing steps.
Will my raw fiberglass part need fitment or finish work before install?
Yes, plan on it. Raw parts ship in a smooth gel-coat finish, ready for your shop, but hand-laid fiberglass is meant to be final-fit and finished to each specific car. Expect minor gel-coat prep, edge dressing, and test-fitting before upholstery or paint for a clean, perfect result.
Do interior parts come painted or upholstered?
No. Dashes, panels, and A-pillars ship raw in a smooth gel-coat finish, ready for your paint booth or upholstery shop. Paint and upholstery are handled on your end. An upholstered offering is planned for the future.
Can Fesler pre-fit, wrap, or upholster my part for me?
Yes, as a paid service. If you would rather we handle pre-fit or upholstery, contact us before ordering so we can quote it. Unless your part is pre-fit or wrapped by Fesler, that final fit and finish is handled on your end.
Is the gel-coat surface ready for paint or upholstery?
Yes. The smooth gel-coat gives your shop a clean, consistent surface to work from. As with any raw part, a light scuff and prep before paint or adhesive is normal for the best bond.
Do you recommend professional installation for interior parts?
Yes. Professional installation is recommended so the part is fit and finished correctly to your specific vehicle.
