What sander should I use to prep my T4, for painting. Is an orbital sander the way to go? Where can you hire them from? What grit size should I start at and what size to work down to? Roughly how long will it take to do the whole van?
pick up a cheapy from B&Q it will probably cost abolut the same as hiring one plus the aggro of collecting returning it. As for grades it depends what you're doing. Is it a same colour blow over or a full on panel repair and paint job?
Use a DA sander (duel action) they remove any tiny swills due to the random action. I would either wet and dry all over with a block using 180 grade, then fine grade scoth pad over that. However thats if the whole van is perfect any repairs and its more involved than just sanding.
