Majic Rust Preventative Sandable Primer, Gray, 1 gal. is rated 4.3 out of 5 by 3.
Rated 4 out of 5 by from Does not dry. Bought it straight off the shelf. Took a 4 inch steel dry wall mixer and mixed this stuff for fifteen minutes. Bogged the drill down. When I thought I got it at a good consistency, I strained it,chunky as all get out. Applied it. Six days later.....Now I have a vehicle covered in chewing gum. Gonna have to strip it all off. Don't know if it's the product or the store I bought it from. Anyhow, money down the drain. Hate to leave a bad review, but.....I won't because I like everything else you provide for me.

do i need to use a  hardener with this primer ?

Asked by: gardenman
Majic Catalyst Hardener is always an optional “accessory” to a finish paint system, and is not required - however the benefits of mixing Majic Catalyst Hardener into the enamel finish are increased film hardness (greater abrasion resistance), and accelerated curing of the paint film (reaches maximum film hardness sooner than without the use of a catalyst hardener). The advantage of using Majic Catalyst Hardener is best realized when used only in the final coat of the finish enamel being applied – It would cause no harm to add Majic Catalyst to the primer (e.g. 8-6055 Sandable Gray Rust Inhibiting Primer), but would NOT result in any appreciable advantage by doing so – and because of the slightly different structure of primers versus finish products (from both compositional and solid contents perspectives), it could be argued that, in certain conditions, the use of a Catalyst Hardener, added to the primer, could result in a softer film due to the catalyst’s attraction to ambient moisture (humidity). The best rule-of-thumb regarding Majic Catalyst Hardener is to use only in the finish Majic Tractor & Implement Enamels, and do not use with Primers. It also should be noted that Majic Catalyst Hardener is NOT RECOMMENDED for use with: • Majic Clear Coat High Gloss Lacquer, #8-2999, • Majic All Purpose Oil Base Gloss Enamels, or • Other brands of finish Enamels (e.g. Rustoleum Products). We hope this information helps!

Can this primer be applied over previously painted metal surfaces that have been prepped with a rust converter, such as Klean-Strip Phosphoric Prep & Etch? I plan to remove loose paint and rust, apply the converter, then prime & paint.

Asked by: XYooper906
Yes. The previous coat of paint must, of course, be clean, dry and free of any surface contaminants that may inhibit the adhesion of Sandable Gray Primer. The existing paint must be in good, sound condition (not flaking, cracked or peeling), and should be sanded with a medium to fine grit paper to “profile” any gloss still remaining for a greater mechanical bond of primer.

How long do I have to wait before I can block the primer 

Asked by: Whatcha483629
When Majic Sandable Gray Primer, #8-6055, is applied in strict accordance to package directions – with special emphasis on the recommended applied thickness of 2.5-3.0 mils wet, and allowing a minimum of 24 hours dry time between coats, block sanding may begin 24-36 hours after application. If product is applied too heavily, and/or re-coated too soon (less than 24 hours), more time must allowed to ensure thorough drying and proper cure.

Can a spot putty be applied over this primer as you would auto sandable primer?

Asked by: Lil guy
If necessary, yes… make sure the Sandable Primer is dry & “hard” (best to wait 48-72 hours before applying auto putty). For best appearance & results, We recommend a light “scuff” sanding of the putty, with 350 grit paper – then apply a thin coat of Sandable Gray Primer over the putty, to eliminate, or minimize, any porosity differences between the 2 surfaces before applying finish enamel.

What do I use to reduce the primer

Asked by: Crimson21
For the Majic Rust Preventative Sandable Primer – thin with Majic Reducer, at a ratio of 8:1 (8 parts Sandable Primer to 1 part Majic Reducer). An 8:1 ratio will usually provide the best reduction for spraying, but depending on what type of equipment is being used, what the atmospheric conditions are at the time of application, and the end-users personal preferences, more – or less – reducer may be added to the mix.

Do you need to take all the rust off before applying the primer?

Asked by: woody10120
Extra care should be taken to remove all loose paint on metal surfaces so that all rusted areas will be exposed for priming.

Can you use this primer on fiberglass?  If not, do you have a primer that will work on fiberglass?  Also, does the Majic system protect against UV rays?  Thanks!

Asked by: Thoran8888
Yes. You are able to use it on fiberglass, please assure that the surface does not have contamination and or is sanded before applying. Yes, it will protect against UV rays.
