can any one help me with a rust problem. i have a area in my engine bay where it is just metal spot no paint nothing in the area. just straight up metal and is beginning to show rust spot. i know that i grind out the rust spot, but what should i use to treat the rust to prevent future rusting. what should i buy to get rid of the rust spot.

 

i would say grind the rust out and get some Krylon spray paint and paint over the bare metal... if you get all the rust and paint over it i dont see why it would come back.

 

Others have had spots like that. They took it back and had the rust treated and touched up by the dealer under warranty. Otherwise if you want to mess with it yourself just sand down the area with some 320 grit paper. Then wipe with some rubbing alcohol and prime it and paint it. Should be a permanent fix.

 

if looks aren't a major concern try:

you can get some spray at your local auto paint store, in a rattle can that turns rust to a primer, do that then paint

 

I agree, great stuff and honestly if you use it right it looks great plus you can paint right over it with a different paint if you want. Just don't get it on your skin and let it dry or you'll be wearing it for weeks.

I used it on the (rusty) rear axle and bunch of the suspension pieces on my Camaro and the results were great.

 

An awesome rust neutralizer, BUT, if you want to paint over it do it while it is still tacky (try this on a test item first to make sure your top coat paint is compatible with the POR-15), or if the POR is dry be sure to sand thoroughly with about a 320 -400 grit before painting. I prefer to sand POR with 180 grit and then prime before sanding and painting if the POR is dry. POR drys very hard and very smooth topcoats WILL NOT stick to it unless it is well sanded.

 

I sanded the POR before I applied primer/topcoat, I never thought about putting it on while it was still tacky. Good advice! I still have some other things to do the POR treatment to so I might just give that a shot.

 

Actually POR product use suggestions state that if possible the best topcoat adhesion is obtained if applied before the POR is fully dry. Be sure to paint a test on something you do not care about (not your forhead as POR stains the skin for a week too 10 days), to be sure there is no lifting or other bad interaction.
