Crash, about seven years ago, i sprayed a truck frame with a product made by rust oleum. it was called DTM but since it was a 1-1 part a and part b mix i would say it is an epoxy? i wouldnt think it has a practical application in most automotive painting but it has lasted very well on that truck frame. it was a very thick material. i'm wondering if "DTM" may be some manufacturer's name for epoxy? i find many manufacture's names for products to be confusing. a big reason i wound up here, i mostly understand what it is.I always wonder how much of a gimmick DTM is. If it's so great, you'd think everyone would use it.
DTM means "Direct to metal". It is used by many manufacturers with various different types of products. It doesn't mean epoxy or anything specific other than you can apply it directly to bare metal. It is not a standard, nor does it signify any type of quality. Just a generic term used by manufacturers.Crash, about seven years ago, i sprayed a truck frame with a product made by rust oleum. it was called DTM but since it was a 1-1 part a and part b mix i would say it is an epoxy? i wouldnt think it has a practical application in most automotive painting but it has lasted very well on that truck frame. it was a very thick material. i'm wondering if "DTM" may be some manufacturer's name for epoxy? i find many manufacture's names for products to be confusing. a big reason i wound up here, i mostly understand what it is.
yeah, there is a lot of word foolery going on. just like "epoxy" spray cans. i cant see how a real epoxy can be already mixed in a can.DTM means "Direct to metal".

Most of the time when it is used, it means a cheaper to make product than epoxy that will sort of adhere to bare metal. Notice how manufacturers always call epoxy, epoxy and leave the DTM part out? Usually DTM is some sort of modified polyester or urethane.
Mix ratios do not signify what a product is. If in question refer to the manufacturers technical data sheet and MSDS sheet to find out what the product actually is.
Some products have a button on the bottom of the can that you push to release the 2nd component into the can, at that point the can must be used up within a certain time period. I would not use them, but they exist.yeah, there is a lot of word foolery going on. just like "epoxy" spray cans. i cant see how a real epoxy can be already mixed in a can.
iv seen those, but i am skeptical.Some products have a button on the bottom of the can that you push to release the 2nd component into the can, at that point the can must be used up within a certain time period. I would not use them, but they exist.
i suppose it may be better than regular spray bombs, for frames and such. i couldnt stand spray cans doing truck or trailer frames though, take forever.IF a person was confined to spray cans for whatever reason, then such a product would be worth testing. Otherwise, it has no place in a professional repair environment.
this, i was hoping to hear. however, the spi ss is not 1-1 mix. perhaps i am simply over thinking things. in any event, its what im going to use because i believe it is the best option for me.SPI single stage is a high solids polyurethane.
The old Imron was a polyurethane also.
i didnt know this. so the ratio does not mean it is or is not an epoxy, or a poly. thanks for taking time to explain this crash, i appreciate it sir.Mix ratios don't signify product type. There are 1:1 and 2:1 epoxies, and 1:1, 2:1, 3:1, and 4:1 polyurethane clears. SPI doesn't make any 2:1 products, though, iirc. Mix ratio doesn't really say anything about quality either. What it does say, you'll have to ask Barry, but it's really just how the manufacturer wants to put it together.
Hi Barry. ha, i almost wish it still was. 1-1 just makes so much sense to me. maybe im strange or a dinosaur lol.Our SS used to be a 1:1 mix, but a lot of complaining. I don't need 2 gallons, so I changed the nco to a 4.1
It is the same product, just a different mix ratio to make it more childproof.
Also eliminated the tech calls; I mixed it 4.1 instead of 1.1. Am I in trouble? Yes!
