OK. I've got 2 similar reflections taken side by side. The cloudier picture is with 3 layers of SG and taken under overcast skies. The brighter one is the one with 1 layer SG and taken in bright sunlight .
Although the light conditions were different, I guess we can still scrutinise the degree of orange peel and reflection sharpness in the 2 pictures.
3 Layer SG
1 Layer SG
Honestly, not much difference if you ask me . But the added protection is a plus for the additional elbow grease and back breaking work lah .
Next week I will try to add on a layer of Carnauba #26 and compare the difference again.
Cheers
