not so much.....Vinyl is forgiving and will allow for variances in finsih quality.
yep , and if your just trying to make a smmoth tranistion between the ring and the face of the enclosure . Chamfer the outside top edge of the ring a little. Do this and you won't get that "edge" where the ring stops and the kitty hair begins. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gifyes USE kittyhair.
you dont have to use bondo or rage gold.
