I have a car which I am going to have fully stripped and resprayed (among many other things which I will not bore you with here because it is not relevant here).

I am potentially looking at making the arches wider, I have found some fiberglass arches for the car which are design to be riveted in place.
Problem is I do not want to have the riveted arch look (it just would not fit with the style of the car).
So I thought that possibly the guy who I hire to sort out the bodywork could smooth over the arches and blend them into the body with filler before it gets sprayed.

my questions are;
1. Has anyone else done this with good results?
2. If I go down this route am I at risk of the paint around the arch cracking when the arch flexes?
3. Is there something I could do to the underside of the extended arch to strengthen it to reduce the chance of it flexing?

Thanks in advance biggrin

The answers are :-

Yes it can be done
Depends on how good your painter is
Depends on what materials he uses

The best way is getting metal arches welded on, smoothed, filled and painted.

Fibreglass expands and contracts at a different rate to metal so there is a possibility that you will get cracking on the join over time.

The alternative is to buy whole panels with widened arches - then the joins will be away from the arches so if they crack they won't be noticeable.

Spot on advice, joining fibreglass and metal will always show it face over time
