filling in angle grinder marks

[oapt25]

I have a few otherwise flat panels on my van that have a fair few quite shallow but noticeable grinder marks on them. They are in bare metal now, and im wondering how best to fill them. Would i need to give it a skim of filler over, or would the high build fill these in?

Filler needed OAPT. High build primer is good, but it can't work miracles!

But then again, depends on what you're looking for in the final finish?

A finish not full of grinder marks hopefully! Thanks for the reply, i've ordered some fine filler so will give it a quick going over tomorrow.

Watch when using a flap disc that you dont press too hard, flap disc followed by a surface conditioning pad should do well, especially if it is going to be DAd off aswell.

Cant you polish them out?

I use a bit o'filler, then sand back using a 180 or 240 pad on a DA. Usually gives a nice flat finish.

I find flap discs are good for major sanding especially on curved areas, but for flat surfaces I find sanding discs with the flat backing on a grider is better than the flappers
