Hi, I have to paint some doors that were painted with rustoleums john deere green. Since it is a high gloss paint I will have to sand them but I don’t want to rotary. Thanks Mike sand because of marks. Will i have a sanding mark problem with a finishing sander, HF has one with a small triangular pad. I think it is orbital and a hi fine sand paper such as 150 or higher, The doors are metal

Can you scuff them with steel wool, green or red scotchbrite pads?

I can’t offer a complete solution to your problem, but I do not think the small detail sander is what you are looking for. I have one (a Fein, not the HF) and it is great for many uses. It is not an orbital sander. The pad oscillates in a small arc around the pivot point of the shaft. Proof of this comes in the fact that you can fit these units with small circular (or semi-circular) saw blades. They do not move in an orbit, they just oscillate back and forth in a circular motion around the axis. As an aside, you can gently touch the saw blade and the natural give of your flesh prevents any cutting. Touch it with a firm piece of wood and it will cut into it.

I agree that you do not want to use a “rotary” sander (a pad mounted on a drill???). You probably want a true random orbit sander with some hand clean-up in hard to get at spots.

If you are sanding because you want adhesion of the new paint to the old gloss surface, have you considered using a paint deglosser instead? Much easier and can get into areas you can’t easily get to with sanding.

Are you a hand plane user? If not you can use a paint stripper since you are only looking to take the gloss off you can use the less harsh ones. Peel away works good.
