if i can do this tarm...there is no doubt you can handle it...very simple to do with very little prep work...how long will it last?? i hope a long time..i just sprayed a couple weeks ago..this stuff goes right over surface rust.. you need to remove all loose paint and flaky rust..i used a needle gun to take off the flaky stuff.. sanded the heavy rusted parts... degrees every thing with simple green or what ever...dry it good...i used there stuff called mettle blast..its an acid that neutralizes the rust..it also acts like etching primer..spray it on wait 20-30 minutes and wipe it off or rinse away..if you rinse make sure its very dry before you start spraying..we have HVLP set up at work..even though we have a paint booth we also have a outside lift with a cat walk..it was a nice weekend so we used that.. it made life easy..the rust bullet is silver kinda like the dull side of aluminum foil...put on 3 coats of rust bullet letting it get sticky without sticking to your finger between coats..8ml thick if i remember right..after doing the under side i decided not to go black under there..you could see it get brighter as you painted the silver under there..i thought if i broke at night i might be able to see much better with a flashlight bouncing off all that silver...so i taped off my spring hangers and U bolts and shot the out side of the frame rail with black shell with 3 coats..its a high gloss black...then sprayed 3 coats of clear shell over the rest of the silver...they also have green,red,orange,blue,black, white,purple yellow and clear shell... ColorShell coatings are high visibility, UV resistant rust inhibitive that wont crack.peal,chip if applied right..like the rust bullet the shell is also self leveling..wont show brush marks if done by hand....hard to make it run if sprayed..after a week i smacked my frame with a hammer a few times..did not beat it.. just a few good smacks and didnt hurt this stuff a bit...it is also resistant against all kinds of salts and acids...i bought this kit
