Post First hints of rust.

What do you do when you see the first signs of rust?

I can see the metal cancer beginning to show up in several areas. Mostly small crevices or in locations which make repair difficult, impossible or too time consuming to contemplate. Just shoot the area with a rust killer and protector like Fluid Film or Rust Check?

Just shoot a little spray paint over it to hide it?

Or should I think about sandblasting the area and using a little POR15? The trouble with POR15 I find is that often the source of the moisture is the other side of the repair and the spot eventually rusts again anyway. Also sandblasting is such a mess.

Living in the 'Rust Belt' - I like to get the cancer before it can take root... Blasting is best in something like a seam- ever tried a 'Spot Blaster'? many companies sell them and it controls the sandstorm quite effectively- takes a lot longer but if you just want a seam cleaned they are great.The rubber tip holds the sand in just the area you want to blast and if you're good, you only need minimal body protection. You are correct in finding the reason behind the rust- if it is coming from behind it will do no good to just clean the front. Good luck and kill that cancer!!

I bought a spot sandblaster last week.

Tried it once not very impressed with the results so far.

Going to have to play with it - will and try different media and pressures. If you have any advice on how to use one of these things I would love to hear about it. <img src="confused.gif" border="0">

Spot Blasters, like any tool they are a 'you get what you pay for' kinda thing- I've used cheaper ones, but they take longer and you have to push it up tight against the panel- pull the trigger and wait... usually a better one will take just a couple seconds- if you have the rubber tip assortment, you can try different ones to get in tight to the area blasted- make it fit tight and use the maximum pressure allowed by the manufacturer- lotsa air means a better blast. I've done a body seam behind a door in about a half hour- takes a while but gets it clean. I stll like using silica sand, but friends like small glass bead. Good luck and give it another try- if your compressor is keeping up I think you'll see results.
