Do these bolt on or glue down?

They slip over the existing handles. No adhesive or fasteners required — just slide them on and they seat themselves. The fit is friction-based, so make sure the handle surface is clean before installation.

Will these hold up to washing and weather?

ABS is solid against UV, heat, and cold. Regular car wash won't damage them. Just avoid high-pressure spray directly into the seams, and they'll last through years of road and weather without cracking or fading.

Can I paint these if I want a custom color?

ABS can be painted, but it needs prep — light scuff the surface before priming. Standard automotive primer and paint work fine. Test fit them first to make sure the paint doesn't interfere with the friction grip on your handles.
