Long story short, while rolling my fender, ended up cracking the paint pon the fender, from the lower edge (middle of the radius) about 5" up.
Looks to be about 1/16-1/8" of filler on the entire fender (they were previously reshaped by the PO), filler looks to be grene in color, similar to the flexible glazing putty i used on my urethane bumpers. Paint is single stage black.
To properly repair it, should i:
- completely sand the cracked paint/filler area to bare metal,
-feathering out approx 4-6" from the affected area,
- 400 grit the entire fender,
-body fill the sanded void,
-then respray the entire fender with my new single stage (I have used Tamco before for my bumpers and really like the way it lays down and its flexibility)

I did blend the single stage on a damaged area on a rear bumper, I did have to do alot of sanding and buffing to get it to blend in, which is why I am suggesting just painting the entire fender.

Please let me know your thoughts!

Remove all paint and filler from affected area.
Roll away.
Re-apply filler as necessary, shape and finish sand P400.
Prime and sand.
Paint the whole guard.

Blending 2K can be done, but not by sanding and buffing. The correct way is to use a blending thinner to melt the edges in. That said, it is more of a pro technique that needs some knowledge and practice. If you have paint that matches then probably easier to just paint the whole panel.

Thanks, I wont attempt a blending thinner.
So you recommend filler direct to metal, rather than an epoxy primer first?

Thanks,
Greg

Six of one, half a dozen of the other.

Usually my jobs are relatively small so I go direct to metal. For big jobs that have been stripped then I'll epoxy first to seal the metal, especially if filler work might not happen for a while.

Up to you. Either way is acceptable.
