Like our clears, we wanted to develop ultra-high-quality foundation primers.
Our 5300 series primers boast a true direct to metal resin (same as in our clears) which means it can be used on the entire vehicle. Many others claim to be direct to metal but tell you not to apply on anything larger than the size of a quarter. Another unique attribute of this series is that has a really high build much like a polyester filler primer. However, while our build is the same, it has flexibility and won’t crack like a polyester. It also uses an actual ISO hardener that allows it to crosslink to the substrate. The cheaper polyester primers only use MEKP which does nothing than offer a chemical reaction which is a weak point in refinishing. If that wasn’t enough the 5311 has rust encapsulation properties. What that means is that if you have blasted a car and it sat overnight and has flash rust can simply scuff and clean the panel and apply directly over the rust. We have actually taken this to the extreme to see how well this primer will encapsulate. Over 10 years ago we took a rusty panel and applied 5311 over it. Since that time it has been out in elements and the rust has not come back through. As said this is an extreme case and we don’t recommend going over heavy rust like this but the product has proven to withstand the torture. Another nice feature of the 5300 series primers is that they can be reduced and used as a silky-smooth sealer which allows you to use one product instead of having to buy a dedicated primer and a dedicated sealer. It is available in white, black and grey. These products were not designed to provide protection on vehicles left outside in the elements and we recommend first applying our DTA epoxy first if using on a long-term restoration.
HP5310 is a work horse for sure! I’ve abused this product and pushed it past the limits! Still no failure! 4:1 with 2.5 tip is 3.0-3.5 mils thick !!! Sands like a dream! Love it
5300 series primer is the nicest spraying ,filling and sanding primer that I have ever used to date.Doing a ground up restoration on a 1968 AMX.will be using Rock It Red,Stars and Stripes white and Freedom Blue,to be followed by 2104 Clear.I was amazed at the results and sprayabilty of the 5300 series.The flow is phenomenal,no dry ,cat tongue roughness as with other primers even in 98 degree temps. I also used it mixed 4:1:2 as a sealer for the door jambs,and never have i seen such a smooth sealer such as this.went straight to stars and stripes base,then 4100 clear for the jambs. Great product.please dont ever change it. Sincerely,Leo Martin. Martins Custom Paint and Body.
Love the products I plan on using it a lot more to replace the DP and MP epoxies I used in the past it’s time and money saved 👍
DTM Primers (Direct to Metal)
I really like the primer (black) however it doesn't seem to go far an it pulled rings around my body filler. I'm lead to believe I had a bad batch of filler however I think I'll just stick with your clears for my complete sprays for now
