Default 66 engine Compartment Paint

Attempting to detail 66 my 66 coupe engine compartment and I'm having trouble getting a smooth even semi gloss black finish for the fender side walls. I've been using Rustoleum semi gloss black from Walmart but the finish is not consistent with some areas too shiny and other areas look pretty correct. Krypton has a paint for plastic but it "alligators" when applied. I've sanded after painting and re applied with the same inconsistent results. Can anyone recommend a brand (semi gloss black) which is better suited for the fiberglass engine compartment? Technique for applying?

Thanks

John Deere Blitz black is the best rattle can that i have found, it provides great coverage and flows out to a nice satin finish. I often use it for base coverage and then finish with SEM Trim Black Satin.

Eastwood makes a satin black that provides even results ,its called under hood black. or you could order from Long Island Corvette supply, their satin black is also very good, Prep is key to a even finish,

Besides cleaning and sanding smooth, what preparation do you recommend?

If your target is to restore to original, I wouldn't sand the skirts. Especially the junction between the outer fender top and the inner skirt.

Wipe it down with wax and grease remover, lacquer thinner, acetone or alcohol before painting.

If it’s alligators that means it’s lifting and surface is contaminated and or the stuff your using is enamel and spraying that over lacquer will cause that too. Your going to have to strip it and start over

So, the engine compartment was originally lacquer? Strip it?? How about a good sanding and sanding between coats?

I want to restore the appearance of my undressed when I swap out my old engine with the one I'm building now, but the specter of stripping it down to bare fiberglass does not hold much appeal. My old black underhood paint is not alligatored, but it is too glossy, and waaaayyyyy too thick, plus it has areas of severe contamination under the paint.

Yuck.

This might be one of those examples of 80/20 being the correct approach.

if your paint is lacquer and you spray lacquer over it and itís clean then you will be fine. He sprayed enamel over lacquer with no slealer or primer.

I agree. Very close to GM factory color and gloss. 👌

Fully AGREE- recently tested out 5 different recommended paint brands and gloss levels. Blitz Black was spot on with my ďoriginal ď painted engine bay. You MUST apply it according to instructions on itís can . It must be MISTED on lightly or it will be too glossy for your OEM requirement. Coverage is very good.

Found the John Deere Blitz Black on Ebay...going to prep as much as possible, but NO stripping...will apply light coats and sand between. Should be good enough for my NOM 427/450 engine compartment...but it's a date correct 9942 block with all the original parts...so I ain't gonna quibble about the artistic value of the "semi gloss black"...thanks for all the comments

Your local John Deere dealer should have Blitz Black in stock.

I have had good results using Krylon #1613 semi-flat black "Industrial/Industriel" marked on can. You will need to buy from an on-line supplier such as Amazon or an industrial equipment supplier. It is a lacquer base paint that you can apply in multi coats. Don't be fooled by the Krylon #51613 satin black "Indoor/Outdoor" readily available at the big box stores, it is not the same product as #1613! The 51613 will "alligator" with multi coats.

Blitz black was the NCRS standard for semi gloss black paint up to about 2005. John Deere changed the formulation and P/N to 25631. Depending on how **** you are on gloss the old JD blitz black P/N Pt 107 . is what you want.if you can find it.

You DON'T want semi-gloss black - you want a semi-flat black that dries to an "eggshell" surface, and you don't want the ENAMEL you're using. You want a lacquer like SEM Trim Black or Krylon #1513 Industrial 5-Ball Semi-Flat.

wow. Never knew there was a difference in semi gloss and semi flat. Learn something every day. So, you are saying the krylon semi flat is a lacquer paint, not an enamel? Thanks.
