Questions & Answers

So technically, I can grind a panel to bare metal, bondo imperfections, 120# the whole panel (or vehicle), apply this, dry sand with 400# and go right to base/clear? ("Technically"! Not saying I wouldn't use a sealer.)

Asked by: rick
Technically Yes!! This is a Direct to metal(DTM) product so it can be applied to bare metal and will fill 36 grit grinder marks in 2-3 coats. Then 400# sand and paint.

Besides the prices, what exactly is the difference between this and Contour? Featherfill?

Asked by: rick
All three Polyester Primer Surfacers you mention perform exceptionally well. They all have similar properties and are great at filling (high build), fast drying to sand times and are easy sanding. Other than cost, personal preference and past experience is usually the deciding factor.

Can you spray enamel over this without adverse reactions?

Asked by: Rugerp904579
You shouldn't have any issues applying enamel over this product. An option should you sand through anywhere would be to apply a sealer primer over this and then apply your enamel (reduce our epoxy 20% to create a sealer).

Just primed my lotus and it looks great. How long can I wait until I can top coat. How can I tell if moisture gets in or not?

Asked by: Tombuck
There really is not a maximum time frame to top coat this. It can be top coated whenever as long as it is block sanded first. You will visibly be able to see if moisture gets into this primer. If it will be subjected to moisture or humidity we strongly recommend top coating this with a sealer coat of Epoxy reduced by 20% with Urethane reducer.

If you spray on a car that is garaged will the moisture in the air be enough to cause harm over two weeks?

Asked by: Tombuck
