Welcome to the forum!

 

Moving this over to the Paint/Body Section.

 

I would apply an epoxy to the bare SMC and then prime it.

Not knowing what type of bumpers you have (urethane or fiberglass)..I can not comment on what to put on them until I know that.

front is urethane ,rear I after market fiberglass ,got from Corvette Central, thanks DUB

 

The PPG DPLV epoxy primer is thicker and has some build properties rather than the DPLF which is watery. Porchdog likes the SPI epoxy primer. I have just finished painting my '64 using PPG materials.

 

Is either of these TINTABLE

 

i would spray it over a white base instead of using $$$$$ color to tint. tinting sealer usually leads to a false sense of coverage.

 

Thank you for this info. I am putting It with all my other info,for when it gets done ,maybe this winter , HOPEFULLY .

 

When in doubt....spray out a test panel and see how it comes out.

Also...I do not know if the place that sells the PPG products will have a NEXA 'color evaluation card'....which is a paper card that has black and white checkers on it that oyu spray teh paint on.

I have them and use them and the reason I use these cards instead of the spray out cards that are already painting in different shades of gray....is that I NEED to know how many coats of my paint will hide the black and white checkers completely.

By doing this..I know that 'X' amount of coats will give me complete coverage and color saturation. Because I have had some paint colors cover in two coats and others....which have a lot of pearl in them ...or the toners are weak and not high strength are so darn transparent that it takes many more coats.

So...when I have color that I am mixing and I see that well over 30% of the weight of the toners is a pearl....I know that I may need to change how I paint the car so I am not wasting a lot of paint that is not needed.

On colors that are that hard to cover...I mix up a solid color toner off may mixing machine that is close to the color and paint the car first....then shoot the car with the correct paint.

So...if your copper paint color is 'orange' so to speak....I would shoot a solid color orange toner and then paint it with the copper color.

BUT...also keep in mind I still have the spray out card of the copper color painted to full saturation and clear coated.....so...when I shoot my next spray out card with the orange paint...and then shoot the copper paint on it. I will know right off the bat that it may only take 2 coats to get it to look just like that I shot 5 coats on.

The reason I do it this way sometimes is to save on material costs and the solid color toners/pigments of the paint system I use are so stout...literally one coat will give complete coverage...so I am saving time and paint. I can not say if every paint companies toners/pigments can do this...so this is why you want to do a test.

Which also is oddly enough...providing you a 'tinted' surface to shoot your color on.

Thank you soo much DUB, I will get back to the company that I got the paint fron ,and get the check cards ,and alsk ask for the tinted orange epoxy primer sealer.

 

There is NO tinted orange epoxy primer.

I did not write that in what I wrote..so I do not know how you read it and came up with that.
