  • Contour Polyester Filler Hardener 3.5 ounces
Contour Polyester Filler Hardener 3.5 ounces is rated 4.4 out of 5 by 43.
Rated 5 out of 5 by from New Catalyst/Hardner I have used gallons and gallons of this product, and for the value, ease of sanding, it is now my primer of choice. I mix a quart at a time, 1/2 bottle of hardner, with a small (capfull) amount of Acetone. With a 1.8 tip and the needle out to maximum volume, it sprays real well. I just bought a 2.2 nozzle, to see if I can move a little faster. All in all, it is a great product. Jsut received another gallon today, and dang, it came with 7 tubes of hardner?? If there were 8 tubes, no problem, but 7 tubes?? I'm glad I still have a bunch of the bottles, so I can divide it all up.

Rated 4 out of 5 by from Good for the money I'm a hard core restorer and buy the best of the best. Typically I stick with PPG and their D822 high build primer/surface (epoxy) but its $300.00 a gallon with the catalist so I thought I would give this a try at 1/4 the price. It fills excellent and sands almost as good as D822 although it dries slower and doesn't feather as well. When feathering with 400 grit you will get the occasional edge break and this primer does NOT do well as a direct over metal. PPGs is self etching and doesn't need a primer prior to applying direct to metal. If you add USCs supercharger product it will GREATLY improve the featheredging and sand ability. For $9.95 on other sites, the Usc Super Charger ‑ Part : 40154 is a PERFECT adder for this primer. 1/2 oz per 24oz of mixed primer. All in all a great value for the price. VERY similar to Evercoats G2 , almost identical in fact.

Rated 5 out of 5 by from another good polyester primer ive used all of the major brand polyester primers over the years. They all seem to aquire their own spray technique. Whereas I could get away with a 1.8 tip using evercoat featherfill, eastwood contour I had to use my 2.2 unless it was reduced the 10%...still a good HIGH build great sanding primer dry and wet. May be worth the $10 xtra dollars to buy featherfill G2 still. But im going to buy the contour primer again..like someone said above..Make sure to measure precisely. You have two Catalyst bottles = 64ounces or half gallon each. Peal of the label, mark the bottle mid way now you have quarts 32oz...divide into four and you hav pints 16oz. Stuff dries fast don't ruin it !!

Rated 2 out of 5 by from very disappointed First off I would like to say I had success and failure with this product. this product works ok for straight panels such as doors, and hoods, but I would not recommend it for use anywhere there is complex shapes such as an engine bay. I will also say that it does shrink, if you use it on complex shapes the possibility of cracking is very real. also this product seems to be very sensitive to humidity, more so than most other primers and fillers I have used in the past, with that said I would not use it above 35% humidity. and if you need to do more than two layers make sure to allow for plenty of dry time between layers. I think the product works ok for what it does but I recommend using it very sparingly

Rated 5 out of 5 by from contour primer hardener I bought this a couple of months ago and finally got around to using it. First i had to overcome the ridiculous amount of recommended drops of hardener for 8 ounces of primer. I solved that problem by getting some plastic suction draw tubes from a drug store. You draw out 12 cc/ml of hardener to cover 8 ounces primer and put it into the primer , stir and spray easy peasy. But counting out 240 drops of hardener, thats really stupid. I would suggest that eastwood include 6 of the suction draw tubes with every gallon of primer. Also the small bottle of hardener is not going to last the whole gallon. It sprayed well with a 1.8 suction gun. Tech guys are very helpful on phone when i ask questions. mike lynch,,,,,,,,,,,,,,,,,,,,canada

Rated 5 out of 5 by from Great Product!!! I purchased my first gallon of Eastwood Contour Polyester primer a month ago and used all of it up already. I had a relatively straight panel to after doing my rough body work with body filler. I then sprayed the Contour primer and I thinned it 10%. It sprayed great through my 2.3 tip. I used dry guide coat and sanded it smooth with 220 and then again with 320. It sanded like chalk after drying for only 90 min @ 70 degrees! The panel is lazer straight and ready for 2k primer after 1-2 applications of the Contour.

Is this a good product to use on my 92' corvette after stripping all the old paint off. The panels flex a bit would I need to add something to this to assist with it not cracking on the flexible panels.

Asked by: Matt A
Yes, this product will adhere direct to metal.. Our primers are not designed to have any additives mixed in; there would be nothing further needed.
