When designing the formulation for our 5310/5212/5313 primer we looked at what was available on the market and and what people in the refinish industry wanted. We came up with a primer that is completely unique in the industry. Many restoration shops use a polyester primer for its build properties to get laser straight panels. The downside to polyester is that it isn't catalyzed and can crack when applied too heavy. Not only that it is very hard to sand. When you use an un-catalyzed product that becomes a weak point in your finish. Your foundation is the most important step on any collision or restoration project. Keeping that in mind we developed a primer that builds like a polyester, is a true direct to metal, doesn't crack, won't shrink on sand scratches, is easy sanding and can even be reduced as a sealer. We combined all those things into one product to make your job easier and save you time and money.

Little breakdown on the details....

HP5310 primer is DTM **The Gateway Primer**

(all over direct to metal) not just small sections. This can be used in place of epoxy on different occasions and projects. This primer should be topcoated ideally within 2-3 months. It's never meant to stay outside Untopcoated.... (like epoxy can be) Store inside only, meaning do not leave it in the elements. This primer has a perfect amount of flexibility built in. It's not brittle and prone to cracking.(as poly filler "primers" are) This primer will not shrink. It's 65% solids. Builds like crazy, It can be sanded in as soon as 45 minutes, Blocks like butter! Temperatures come into play with sanding times. It can be mixed 4:1:2 and turned into A DTM sealer.It may be "value shaded", we offer several colors. This primer Is NOT modeled after another. It's completely unique to Tamco. Nothing like it on the market. And once used that's seen. It's extremely thick. It's meant to be. Most spray reduced about 10% with a urethane reducer. Some 4:1 with a 2-2.2 tip no reducer. The more you reduce, the more the build will be cut.

3M/ Accuspray plastic gun sprays 5310 like a dream at 4:1 with the red 2.0 tip. Best damn primer on the market.

For a newbe this was easy to lay down and sand with fantastic results. TAMCO Rocks.

It sands like butter - really easy to use. This stuff is so thick I have to thin it to go through my 1.8 nozzle. I highly recommend this product. Which reminds me, I need to order some more!

Awesome primer. Very thick in the can so you can have it thicker than a spray poly. Or reduce it to any thickness all the way to using it as a sealer. Direct to metal and doesn't shrink. Love it

5310 is a primer that fills like a poly without the shrink. Was able to completely cover the molded "leather " profile on a 70 Chevelle dash with 3 coats. Dry sands well and wet sands unbelievably. Shoot though a 2.2 or reduce 10% for 1.8. Mix 4:1:2 as a sealer. Try it and you won't want to spray anything else.

The HP 5310 works just like described, I absolutely love it. When ready to wet sand it cuts like butter, I've used it 4:1 and 4:1:1, I highly recommend this Primer. Thanks Tamco.
