Thats exactly what Ive done to mine, Im a painter by trade so it was easy enough for me. As long as enough plastic adhesive is applied after they are preped then they wont suffer with paint flaking off!! A lot of cowboys dont bother with this and make a complete mess of the job. I fully cleaned them, keyed them, applied the adhesive then high build primed them to smooth them. Once the primer had been flatened, I painted them, easy!! Looks the bollocks
