How do you go about building up bondo, mud, plastic fillers to custom build a fender flare. How much is to much mud and how do you get it to hang on without shrinking/cracking? I'm working on a 65 Chevelle thats been quartered and skinned. Someone started to build fender flares with plastic filler. The mud that there is about 1/4 in thick. A grinder was used in several places on the body to tell the depth of the mud and I want to fill it back in and have it stay. <img src="confused.gif" border="0">

you can have the end product as thick as you want but it's important to only apply one layer at a time no thicker than say 1/8th inch. let it dry a day or two before you put on another one to be on the safe side. hopefully HK or somebody who knows mo bout it will chime in.

TM, Building up filler is usually not a consideration when doing custom work. If you want to make fender flares make them from fiberglass or sheetmetal. If you insist on gobs of filler <img src="graemlins/drunk.gif" border="0" alt="[drunk]" /> I would strip it down completely and start over. Since you ground away parts of the old filler getting new filler to fill those places will be close to imposible. It will never be uniform to the exsisting filler, it will always have a crease or gap. If you want to make fender flares let me know and I'll walk you through making 'glass or sheetmetal flares, they will last longer look better and be much lighter and not as fragile.

OOOoooh I just had a shiver go right up my spine reading this post. Do it in steel of don't do it at all, anything else won't last...long. -40 Celcius winters have a devastating effect on disimilar material adhesion around here so I would never do what you are proposing, I have seen the Van craze of the 70's come and go and none of the remnants of these vehicles have their putty/fiberglass flares left-yuuuck!

Hey baby want to ride in the back of my Chebby van? <img src="graemlins/mwink.gif" border="0" alt="[mwink]" /> It's got real shag rugs inside and a water bed frozen solid for us to "rock" the van on!

Just my opinion.

What would be the deal with skinning a new quarter like this? Do you think somenoe used to much heat or to long and warped the sheet metal? I think the fender flare was an after thought once they started skinning the fender. Thanks for the sugestions, I will take replacing the mud with fiberglass under consideraton.

hK is right building these out of filler is bad. Normally filer shouldn't exceed 1/4in. thickness and most techs. wouldn't use but less than 1/8 in. if they straighten the panel properly.
If the quarter has been wiped with filler all over the chances are someone didn't know how to weld and warped it.
