Paint?..

[bwiggs2]

I have a 150cc mini buggy. I am going to paint it and started wiring wheeling it but it is taking forever, I have like a fourth of it done. Can I just sand it and prime it or will the part that is wire wheeled look bad. What would you do.
Thanks blake

Hi Blake,

The new paint will make the wire wheel marks stand out (don't ask me how I know).

Prime the areas that you have wire wheeled, let the primer stand for a day in a heated area, then sand. Prime again, let dry and sand. Repeat untill the marks are filled with primer. I know this takes a couple of extra days but you will be happy with the results.

Hey Blake

I would try and get that old paint off if it is peeling or bad. If it is good and really wont move though you can do what Mike said.

What wire wheel are you using, a drill one or a grinder one? If a drill you may want to check out hf's grinders-

$15!!!

If you have a grinder pick up a flapper wheel with a fine grit if the wire wheel cant cut it.

The above info is good. There is also chemical stripping, media blasting, and paint stripping wheels, which look like this:

what they said but throw in sanding with a random orbital sander. Start with a coarse grit (60) then 120 grit, then prime. done right this will remove the wire wheel marks

One guy told me to just get 400 or 500 wet/dry sandpaper and sand it then prime it then paint it..will that work?

All you need to do is sand it, wipe away the dust with mineral spirits and spray the primer/paint.

These are just small machines. If you just keep an eye on where your paint comes off and sand/repaint your will protect your pipes indefinitely.

I would be interested if anyone has tried truck bedliner spray paints. I've heard horror stories but it seems like that stuff is tough as hell.

wipe away the dust with mineral spirits

For a really good job, use Acetone, Methyl Hydrate, or any of the other high-grade solvents. Off-the-shelf mineral spirits ("paint thinner", "Varsol", etc), tend to be of a rather low quality and have a habit of leaving a residue on the metal, which will impair paint adhesion.

What sand paper should I use? I want to get it done fast

 

[kendelrk]

what i have to say is take a wire wheel (i prefer knotted) and get rid of it all it'll take you maybe an hour of work to get it all gone, well at least for my mini bike. Now take a self etching primer and give it two coats one to cover everything one of a nice smooth surface, now take a nice paint and put multiple coats and by the end of about 3 days of painting and putting on a few coats and also drying, it will look extremely nice

 

[bwiggs2]

An hour? I have worked on it like 5 hours and got like a fourth the way done if that.. The wire wheel takes FOREVER

 

[kendelrk]

With one you put into a drill, angle grinder + wire wheel = fast paint remover, it makes the paint come off quick

I still have to say go with an angle grinder and flapdisk. Get a 80-100 grit disk. They go through paint like a knife through butter

 

[ghostdog]

It wouldn't hurt to buy some aircraft paint stripper and brush that stuff on. Let it sit for about 2 hours then attack it with a wire wheel or paint stripping disc like linked above.

The stripper really weakens the hell out of any paint. Make sure you definitely wear breathing protection and do it outside.

A little tip about using the paint stripper on stuff that has A LOT of paint is to slap it on the part and then cover it with a clear wrap like Saran Wrap. This allows it to work without evaporating. You can scrape it off in about 2 hours to the bare metal in one swipe.

Taking all the paint off just takes absolutely forever.. I want to get it done in like a week

Paint stripper is your friend.

I just don't understand why the he// you're going to all this trouble, anyway. If the original paint is THAT HARD to strip off, it will be a GREAT substrate for the new paint. All you have to do is give it a scuff-sand with some 150 grit to remove the gloss and give it a tooth.

The only paint you HAVE to remove is loose, bubbled, and rusty stuff. Stop killing yourself.

And if you STILL feel the need to strip it bare, HINT- HEAT!

Ok I'm going to sand it, prime it and then paint it...I'm just worried about the part that is wire wheeled showing

One guy told me to just get 400 or 500 wet/dry sandpaper and sand it then prime it then paint it..will that work?

This will only work AFTER you prime. Prep the metal as I suggested, prime, then rub down with 400 & you'll have a paintable surface. Clean with wax & grease remover & then paint.

As for using high grade solvents (as suggested by toystory 4wd) only use it on the bare metal, never on primer or paint, & allow plenty of drying time otherwise adhesion could be a problem.

P.S. I'm a panel beater so I do this stuff every day...
