surface prep tips for gaskets

Got any tips on ensuring clean, undamaged surfaces for gasket install (especially split cases)? tips and no-no's, success and horror stories welcome

Its soooo easy to damage aluminum with a razor blade as I've discovered.

What do you use? Scotch brite pads? plastic scrapers? those nubby plastic grinding pads car guys use?

If I can split a case and make it work - you can too!

I used a razor blade carefully for cleaning up the block mating surfaces, then ordered a gasket scraper and some gasket removing spray. Haven't tried those yet. The razor blade worked well enough if you're cautious, but it takes a lot of time to do it well. When I was done with the blade, I wiped everything down and ran over it with aluminum polish.

I use Three Bond gasket remover and a plastic scraper

In the past, I've used Popsicle sticks in place of a plastic scraper. I just cut or sharpen the end of the stick so that it is like a knife's edge. I didn't cut the side of the stick, only one end of the stick. Then I scrap away. When it gets too dull, I just resharpen it.

Don't take my word for it. I'm just a foolish newbie.
When in doubt, just know that I am only joking around.

Finally, somebody mentions my screen name. I worked very hard on that. My favorite part is that it contains the word vulcan.

Such a slick name and such a fancy profile pic, I just assumed you were a long-time member!

Vulcan slang for newcomers

Shoot, I wish I was a long time member. That would've mean that I had my bike for way longer. I should've started riding a long time ago.

sandpaper wrapped around glass gives the flattest surface, but some things have nubs sticking out so you cant lie them flat on the glass.
