What Should Be The Material?
When spending money on the best sander for fiberglass, you must check the material. Most models are made of heat-treated steel components that provide long-lasting services and resist wear.
These sanders are best for metal, wood, and fiberglass. Always pick the durable and easy to use a lightweight sander.
What About Hand Grips?
Sander is a machine, and holding it safely and securely is necessary. Most powerful sanders produce heavy vibrations while working.
Contrary to this, small sanders want intricate control for avoiding damaging the fine details. The vital component of sander grips is their composition.
Remember that sanders having soft grips are comfortable to hold and control. So try to pick one that is built with a soft grip.
What is The Suitable Design?
For fiberglass, the dual-action sander suits best as it has an ergonomic design that best fits comfortably in any hand and gives smooth control.
A sander having a light design is simple to handle, and people can manage to hold it for hours. Even you can even finish sanding the large areas.
Another option is a sander that has an air inlet, so the debris will stay away and disturb you while sanding fibreglass. You can also check the palm sander as it delivers faster removal and gives a well-blended finish.
Use Medium Grit
The main objective of sanding fiberglass is to get rid of the exterior gloss finish so you will get the proper surface for painting again.
If you are working on small projects, go for at least 120 to 180 grit sandpaper. For large projects, experts suggest sandpaper having medium grit.
Dust Collection System
A sander having a dust collection system is considered the best for fiberglass boats. You know dust creation while sanding is unavoidable.
There is a method to get around dust for comfortable breathing. Most electric sanders are engineered with built-in dust catching bags. Others show compatibility with the external dust collection system or shop vacs.
What Should Be The Speed
Many electric sanders offer variable speed controls and allow you to run them at a slow speed for managing different materials on the fiberglass surface.
Some sanders have control, like throttles, where a speed adjustment is an option while sanding. Other ones are engineered with selection switches with one to nine ratings.
Trigger Locks
This feature lets you lock the sander in motion by freeing up the hands. You can also lock the trigger on the run settings and clamp it when feeding work on the sanding belt, pad or disc.
