Rustoleum Question

I sprayed my frame with rustoleum rusty metal primer and it dried nicely. Thinned with 100% mineral spirits.

That was on Saturday.

On Sunday I sprayed Rustoleum gloss black thinned with 100% spirits.

48 hours later the paint can be dug into with a finger nail. It's not easy but is soft.

I put a pretty good coat on this side which is the bottom of the frame.

I thought a second coat would be in order and then I'd flip it over and paint the top side with a couple of coats.

Humidity is high here.

My questions are:

Will it dry hard over time and how long do you think for it to dry?

Are mineral spirits not good?

Should I wait until it's good and dry and use a hardener on the following coats or not thin at all and will that have any affects on adhesion?

I just used what I had in the garage and I sprayed it with a gun and compressor.

Thanks,

Tim

 

it will take a week for it to dry.next time use zylene to thin,drys fast,looks good.

mineral spirits does take a long time to dry in high humidity or low temps. don't worry though, it will be fine.

Rustoleum recommends acetone for faster drying times. However it dries VERY fast and can leave the surface porous and dusty. I used about 50/50 mineral spirts and acetone for my t and it came out really nice. I thined the rustoleum about 5 to 10% overall. Just enough so it will spray nice...

 

I think Rustoleum calls for acetoen, but I've sprayed it with thinned with mineral spirits, enamel reducer, and lacuer thinner because it's what I'll had on hand at the time. All with good results except the lacuer thinner dulled the finish. I will dry in it's own sweet time (long that is real long). It will never be what I would call a hard finish. I don't know if hardener would help or not perhaps someone esle will know. Good luck............

 

I just used the same product to prime a trailer frame. On the can it clearly states to use ACETONE to thin when spraying. clean up can be with mineral spirits. I will let you know how fast it drys. Can states total dry time is 24 hours depending on temop and humidity.

Note that the acetone recomendation is a recent change to their recomendations. Some products like the rusty metal primer still call for mineral spirts..

I did find that the rusty metal primer did not do well with the acetone.. maybe it reacted badly with the organic oils in it?? I switched to straight mineral spirtis on this product.

who knows...

 

I shot a set of wheels w/ Rusto thinned w/ mineral spirits to about 10%. I let them cure for a week before I touched 'em, and they setup just fine. I picked a less-humid day down here in South Texas to do it on. I've used acetone onn all other occassions and it turned out a lot better.

 

Thanks for the quick replies. I will let it "cure" for a few more days before proceeding.

Oh yeah. It's humid here all summer.

Rattle cans dry in about 15 minutes

 

Let dry in the hot sun if you can. It will speed the drying.

 

I just finished painting my moms wheelbarrow with the stuff and it will take a few days for the paint to get hard. If the humidity is high, it may take longer. When I painted my truck last year in the garage with automotive paint, the humidity was high that week and the paint was still tacky after 3 days. You should be okay.

 

I have used Rustoleum on wheels and frames etc,and have always thinned it with a fast dry Laquer thinner about 20 percent......works very well can't say about the dulling as I usually am using mostly their Satin black.
Another very good red oxide primer for wheels and such [and also for extended storage] in the primer stage, is B.P.S.....[best paint sold]....its at Tractor Supply Stores.......7 bucks a quart.

 

Good News. I just saved a bunch of money on my......

OK maybe not.

I set the sucker out in the nice 80+ Mid Mo sunlite today and she baked real good. I got busy replacing the oil pan on my 68 plymouth and didn't get the next coat on so tomorrow night is the night.

Thanks to all who replied. It dried pretty well after 72 hours with 6 of it in bright sun. Good thing too cause I missed some spots I wouldn't have seen in the dense building that I painted it in so now I can put a second coat on the bottom side and flip her over for a couple of coats on top.

Thanks again. I can't wait to get the frame painted so I can put the body on and get busy.

Tim, we put those floor boards in your not gonna be able to see that purty paint anyways. Jeff

 

HA HA ....wrong rig brother... the body going on this needs no floors.

This is the frame for my 46 ford. I got it in trade from a fellow HAMBer that set it up with a Rod Factory mustang II set up, SBC mounts, TH350 mounts, etc. I am putting together a 327 for her and have a 9 inch Ford rear from a 57 merc. I sold enough at the swap and on the HAMB to get a Chassis Engineering rearend set up too.

I have a nice 2 door sedan body for it that has only surface rust.

However the extra rustoleum is going on the 54 truck frame.

Needless to say waiting on paint to dry is a pain in the backside.

 

i had the same problem with rustoleum..i called them up and asked if it was a problem ..they said it takkes 7 full days to cure at no lower than 70 degrees...it will has also have a odor to when curing..it will go away tho..
