That's fine, but you'll still scratch it. Anything harder than aluminum will potentially scratch it, which is fine if you're going to cover it with paint anyway. If you want it to look like stock, stick with nylon or natural bristles. Regular grime should get softened really easily with Simple Green or Purple Power, so the brush is really just for loosening and removing everything. The Honda block castings have a great surface finish that's really easy to clean usually.

Use Tuff-Strip...its a paint stripper for metal surfaces...It comes in a sprayable can. It run like 8 or 9 dollars a can at Lowes...Spray it on let it sit for 10 to 15 mins and spray it off...Shit works wonders...The metal will be so clean it could be almost to the point of polishing. Ive used it time and time again..Never let me down..give it a shot
(FYI) dont spray the shit on a windy day like my dumbass did...shit burns like hell on the skin...lol...Good Luck

 

Sure thing, boss..


I'll take this under advisement... I don't plan on painting it... Maybe throw a clear on after I'm done to prevent oxidation...

Sure, I'm a fan of rust... Just not in my bay or on key components...

Will it leave a residue? I know related paint strippers like tal-strip and aircraft stripper leave a white residue...

I may get some and try on some smaller components... If I don't like it I'll save it for a hood or something >_<

 

when you use the tuff strip once its sprayed off there will be a little residue once its wet...while its wet take a wash rag and basically wash it with car wash soap. when it drys just take a dry towel or some thing and wipe it down...Ive done it twice...worked really really good

 

spraying something on and letting it eat is better then scrubbing with steel wool or a wire brush anyday...lol
