Best wire brush stripping paint

[Nodroz]

Just wondering about the video you posted, Fabro - how long will these disc last? They seem very weak to me. Or am I wrong?

They're stronger than they look. They're not like sponge, basically, they're like fibreglass strands coated in a hard resin with some grit thrown in. They're somewhere between a wire wheel & a flap disc.

I went through 3 cleaning my trailer panels; that equates to about 6 square metres of multiple layers of paint & rust. They have a slightly shorter life span if you catch an edge but, a flap disc will do that too.

Got mine the other day. EBay £5 special. Worked an absolute treat! Leaves a nice surface for paint too. However, I only managed to strip the swing arm and sheet steel side panels (light surface rust and sciffing for paint). The disc was then destroyed.

I tried a fairly worn flapper disc. Worked pretty good, but no where near as well. Seemed to 'smear' the paint some how instead of strip it off. However the flapper discs last far longer and cost about 1/4 of the price!

I would rate the poly discs 9/10 for ease of use, 9/10 for stripping and finishing, and 5/10 for durability. I was expecting it to last far longer.

2 out of 3 ain't bad

Did you go gently with them? Added pressure will wear them out quicker. They don't like corners either.

The flap discs only "smeared" the paint due to the extreme friction/heat they produce as a result of permanent contact; you don't get that with the strip disc because the contact is broken by the holes

I went fairly gently. I expect it was the corners and welds that did it in.

Probably. Did you get the drill type or grinder?

115mm /4.5" grinder type because my grinder spins higher rpm.
