Correcting a paint with a compound abrasive often leaves behind minor\/lighter defects such as hologram, haze or micro-swirls on paint. The natural next-in-line approach is to refine the paint with a polish abrasive to remove the lighter defects.<\/p>\n\n\n\n

But is this always the case?<\/p>\n\n\n\n

Is usage of polish abrasive always necessary after using compound abrasive on paint?<\/strong><\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n
\n\n\n\n

The answer is : Not Necessarily<\/strong>.

Here are why:<\/p>\n\n\n\n

\u2022 Not all paints are equal.<\/strong><\/p>\n\n\n\n

Some paints are known to be soft, some are known to be hard. Some, in between soft and hard.<\/p>\n\n\n\n

The different hardness of paints reacts to abrasives differently.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

On harder paints, compounding defects are lesser (or less noticeable) compared to softer paints. And due to the nature of paint hardness, a polish abrasive might not have sufficient cutting strength to remove the after-compound defects on paint.<\/p>\n\n\n\n

\u2022 Change of abrasive might not be required for less cutting.<\/strong>
<\/strong>
<\/strong>To remove lighter defects from compounding, a step-down combination will be required.
But that doesn\u2019t necessarily mean there is a need to change abrasives to achieve a step-down\/lesser cut combination.

On harder paints, it is possible that a compound-abrasive paired with a lesser cutting pad will suffice in removing the post-compounding defects and even finish down to a swirl-free finish.<\/p>\n\n\n\n

On softer paints, switching both abrasive and polishing pad is more likely required to adjust to the right combination. A step-down combination on a soft-paint demands more attention and leaps in adjustment compared to a hard paint. <\/p>\n\n\n\n

Here\u2019s a comparison of refining a hard paint and soft paint.<\/p>\n\n\n\n
