if u want to be repainting ur front end every year or two then go for fiberglass

i got a fiberglass front end on my sis's car
she scraped a couple times, it didnt do anything, just scratches on bottom, but she drives normally and doesnt speed much and still she had hundreds of little chips all over the front end in about a year and a half

our local body shop guy that we know told us the bumper was cracked in a couple places too! I didnt even see any cracks
but its costlier in the log run if u know how to drive

if ur a dumass who doesnt know how to drive and keep hitting stuff then go with fiberglass since u can just goto the local bodyshop and they can work their bondo magic on it and make it looking like new again
