Block sanding !
 
Block sanding sucks. I am painting the race car over the winter. Right now i am in block sanding the filler stage. I welded new quarter panel skins on both sides and fixed some rust in the lower corner of the doors. These skins where very low quality as Ames stated in the catalog. Had to skim the whole panel with filler. Had to skim the doors because someone must have sandblasted them at one point in the cars life. Also had to skim the roof because it looks like someone jumped up and down in the middle of the roof. I am starting to remember why I decided to make it a race car 25 years ago.
The car is going to probably remain white. Unless a color jumps out at me.The car was originally a black car. I am blocking to it perfection just in case I decide to go black.
I forgot how bad the dust is, I am at least getting a good arm work out.

Mud on, mud off, Grasshoppa.

I know it's weird...but I kinda like block sanding. I like to choose a sunny, windy day and go outside in the driveway...an inside radius or compound curve does suck though....:)

How well do those long bendy blocks work?

One thing that might help your dust situation a bit, I shop vac the panel instead of blowing it off. Keeps the dust from flying all over the shop!

Durablocks. I like 'em a lot.

I have been using an assortment of durablocks and one 16" hard block for the large flats. I am thinking of starting a progress thread.
I put temporary plastic up to try and contain the dust. It does work somwhat.

I like the soft sanders for contoured sections they seen to work great especially when you get to the finer grits

Greg Reid 12-31-2020 09:46 AM

I like the palm sander for smaller areas also. Just keep it moving and nothing too coarse on the grit or you'll wind up digging yourself a hole..

Yes it sucks. And another vote for durablocks. I found using soft foam blocks (had some stuff that was packed around computer) helped on curved surfaces.

I've also found that various diameters of rubber hose can work well on inside radiused areas with adhesive backed paper. Radiator hose, heater hose, etc.

If we all lived in an airport hanger together we could Amish Barn Raise block sand cars :)

Weather permitting I sand, grind, prime and etc outside when I can just to keep inside spaces semi clean.

Body work and “clean” do not go hand in hand!!
Dura Blocks and self adhesive paper are wonderful IMHO

I had been blocking a 62 catalina ragtop for most of 2020. For most of it the long adjustable flexible sanders worked well. (these are the ones that you can stiffen with metal rods) But the body line extending most of the length of the car I have not decided what to use yet.

Only have a couple spots that need some light filler work, mostly just getting it smooth at this stage.

Dura Bloc makes a half round block that’s probably 12” long. Before that I used straight piece of radiator hose for years. Works just as well and cheap$$ too

Tape along one edge of the body line and sand, fill, sand..you know the drill. Afterwards, pull tape off and tape the other side of the same line...repeat.

I have a couple days left sanding the Slick Sand (spray on filler). Using a dry coat and love it. Makes it real easy to see imperfections. I kind of feel I am wasting my time getting it perfect only to paint it white.

dataway 01-11-2021 02:49 AM

Are you using that over an epoxy primer?

MUSLCAH 01-18-2021 12:49 AM

Smoke a fat one...and blocking primer isn’t so bad...

Yes, I sprayed epoxy before the slick sand. Have the body, doors and front fenders in final primer. Just have the hood and trunk to finish up. I don't think one thing on this car was flat. Now I am dealing with fiberglass hood and trunk lid.

I plan on painting it apart then putting it back together. Should be OK with a solid white.

Can't wait to be done with the dust. Dust get everywhere. Even with plastic closing in one bay. Going to take me a week to clean the garage.
