you wont need different primer perse. With the plastic, if you rub it back to bare plastic you will want to use a plastic adhesion promoter. With fibreglass its a good idea to use an epoxy etch primer prior to filler primer (as it is with bare metal as well, if you have large patches of bare metal I highly recomend using an epoxy etch primer such as DP40 which is availible from any PPG distributor. Its mixed at a 1:1 ratio and very easy to use as well as versitile.)
