nothingface5384- Yes indeed, when you can go the proper prep it makes all the difference! Especially if you can get to bare metal, then things ougtha go great. What I find tricky is the cases where I just can`t do that and have to literally "paint over rust". Yeah, you`re not supposed to do that but sometimes that`s just all ya can do. Rust Converters can help, but sometimes those don`t work out great either.
There are so many things that can go haywire...
If you try the Rust Seal I hope you`ll post back about how it goes for you (and !oh man! I hope it works out OK since I suggested it). Always hard to say how this stuff will work for somebody else...and even just *my* experiences have varied (I`ve had Eastwood`s Rust Encapsulator fail when I would`ve *sworn* I`d done such good prep that it`d work great).
My relative dislike of POR15 stems mainly from a few cases where it simply didn`t adhere, including one time when a bodyshop used it on a frame (frame-off project) only to have it fail miserably (they assured me they did the prep right). OTOH, I have some POR15`ed areas on the underneath of my Tahoe that`ve held up great, so it`s not like I despise the stuff or anything.
The Rust Bullet seems to take a good bit of care when applying, and I have to do more coats than they recommend; the "pinholes from gas escaping" can be problematic.
So far the KBS Rust Seal seems the best overall, but I haven`t used it long enough or for as many jobs as the others so IMO the jury might still be out.
