megs unigrit sanding discs

[jamores23]

Ok so I was using my 1500 sanding disc and they wore out WAY too fast I was only able to do about 1/6 of the hood with a 3 inch disc, now the 3000 disc lasted a bit longer. My method of use was a little drop of soap in a spray bottle of distilled water and lightly misted the surface and the a VERY LIGHT mist on the pad itself .. I NEED ADVICE WITH THESE, IF THIS IS THE WAY THEY ARE THEY ARE A WASTE OF MONEY! BUT I AM SURE ITS USER ERROR!

On the other hand, I think I am done with the MF cutting discs Because none of them stick to my megs mf backing plate any more, the backside of the pad "where it sticks to the BP" is all loose and doesnt stick.. I used surbuf pad yesterday and i must say, AMAZING alot easier to use then the mf pad and alot less product when using the sb pads! Yes, it doesnt finish down as good as the mf pad, but it removes alot more with a single pass and regardless of anything when compounding you always want to follow up with a less aggressive pad and polish... I wet sanded, surbuf/m105 , SIP/white lc pad, and opt spray wax worked out GREAT!

my mf pads are perfect........ i think you need more water to damp sand, not just a mist like a pad conditioner. water should be dripping/near dripping. also, i believe you need to soak the pads in water first.

jamores23, you're already located in Florida... I'd suggest finding a way to make it down to Stuart and take the Detailing 101 and 102 classes.

With all due respect to Mike, just because he doesn't do it doesn't mean it's wrong. I have personally wet sanded cars dripping wet, and they have come out looking just as good as the damp sanding technique.

i do not believe i am wrong even according to mikes article. i do not believe that the OP is using enough water. op is using a light mist on the disc.

"Damp-Sanding Tools, Tips and Techniques by Mike Phillips

Damp-sanding is a machine sanding technique. Damp-sanding is like wet-sanding only you use a lot less water, basically you use just enough water to maintain lubrication between the paint surface and the face of your sanding or finishing disc. It's important that you maintain the right amount of water because if you use too much water your paper will hydroplane and if you use too little water the face of your sanding disc will load-up and become clogged with paint particles and you'll wear out the abrasives prematurely."
