I've noticed some surface rust on my inner arches that I want to deal with. At the minute it looks like simple surface rust that will brush off with a wire brush. On my rear arches there are no liners, but the front has a half liner covering a portion of the inner arch.

Is it as easy as buying a wire brush attachment, some rust treatment gel and underseal?

The whole car was undersealed last year but the arches were obviously not done.

 

yes yes and yes

i use the black bitummen stuff underseal from the likes of halfords etc,motor factors sell it as well,but they had a huuuuge pot so bought the halfords one,still lasts a few yrs with yearly applications LOL

 

Agree with The Rig. Also spray underseal is good to get into hard to reach places

It also blinds speed cameras........allegedly

 

Thanks guys. I'm gonna give this ago once the weather picks up a bit more in April. Quite worrying how much damage gets done by the bad weather we had over the winter.

 

personally i use hammerite underseal which has a good amount of waxoyl as an ingredient. use it on my classic cars .. it also stays a bit rubbery so will deflect stone etc without any damage ...... goes on easy to

 

Me too, just make sure its all brushed and dry before applying.

 

I had the same on my car and I can recommend Dinitrol products HERE

I bought their small car aerosol kit ( DIN02S ) and still got loads left. I used 3125 along seams and then 4941 over the top.

 

Thanks guys. Gonna tackle this a bit sooner that I thought as the weather seems to be getting milder every day.
