I have a 92 shadow I rust got back from sandblaster. I am trying to coat with rust bullet. I have read the instructions for rust bullet and it says Do Not Thin Out. Now I not new to painting I have painted a few cars but not many and know from them that you thin paint so it flows. I have a hvlp gravity feed spray gun, using a 1.8 tip. Its not a high dollar spray gun but it works. Now I have tried to spray the rust bullet with out thinning it and its sprays than plugs, than sprays than plugs. So I would have to say that the rust bullet needs to be thinned but the company says DO NOT THIN. Any advise or suggestions would be appreciated. I need to get this car coated before its rusts up and don't really want to bush paint it.

What about a larger nozzle(tip)?

That’s the largest tip I have. The directions say to use a 1.0 to 1.7 tip which I think my be BS

Like I said I don't paint offten so I only have a few tips for my spray gun

Maybe that "float" of xylene or toluene is the trick, a thin layer of solvent on the surface, stopping it drying out.

I don't either. The tip should be ok. What about the air pressure.

reduce it. I cant see it spraying any other way. Regardless of what the directions say

Oh that's a point as well, it says elsewhere on their site that humidity accelerates curing, and then in those guidelines to make sure you have a moisture trap on the airline, so I guess if you have got "damp" air coming through it will cure it in the nozzle.

One what is a "float of"
I don't think its drying it just plugs the tip becasue its to thick. At least thats way it seems like to me

A float, meaning a dribble of solvent layered on top of the rust bullet, being careful not to mix it in.

Well wouldn't have to dry completely to cause issues would it, just thicken up a tad.

I had a hummer of a time trying to spray it straight. I was even using a water separator before my regulator at the gun and it didn't want to go on straight. It ended up way to thick and I wasn't impressed with the results in a lot of spots. It is holding up on the under side of the car really well though. All in all I am still up in the air as to how I feel about the product.

I have a air/water seperator at this compresser and a filter at the gun to removed moisture

Air pressure 25 psi up 50 psi

I tried everything to get it to spray evenly, and I just couldn't.

Well fortunately for you I am probably the least capable person, so hopefully someone that knows what they are doing will be along to help the both of us. :thumb:

I don't know I might be going to lowes and buy some bushes and a roller to apply it at this point I need to get it covered

It isn't to hard to work with. You are pretty small so you will have a lot easier time under the car than I had even if you can't get it to high off the ground.

Well if you're giving up on spraying, those "pro" high density white foam rollers are supposed to be the shiznit for getting paint on cars.

Is your nozzle internal mix or external? A pro gun will use the air to suck the fluid out. Of course I'm a dinosaur and have only used Binks 7 guns. No hvlps.

I could not tell you its just a cheap gun. I did find that if I thinned it, it would flow ok. I must be to thick to run though the gun that I have.

I end up barrowing the neighbors pressure pot and used it to spray the under carriage and interior. It worked but applied to a little to thick for the body panels. I am going to try some high density foam rollers tomorrow on a test piece of metal and see how it comes out

You were supposed to by to buy the spray-able version...the one for hvlp guns....the other stuff is just too thick. Btw, I love the ----...hard as nails when cured.

Unless they sent me the wrong stuff I did order the stuff that was thinner, but it still didn't work.

I did not realize that at all when I ordered mine. I guess I will have to try it again sometime.

You are right that it is super hard when it cures though.

I'm wondering if it's really worth messing around with. If you have the car completely stripped hit it was a etching primer, body work it, prime it, seal it, and paint it. It sound's like it's going to make more work than it's worth if it's laying on that thick. You'll have a ton of time in to getting the body work straight again.
