Painting tips

Discussion in 'Restorations' started by Zed, Nov 10, 2011.

  1. a good high solids top coat should cover the primer beneath....sounds like you need to apply more topcoat...if it's still darker, lighten the topcoat
     
  2. help please. just repainted a panel in new paint colour mixed by code but it is slightly darker than the rest as that paint has been on it for 15 years so I presume has faded over that time. Can the old paint be cut back to reveal the old colour or do I need to get more paint mixed to match the old colour? It's a creamy brown/gold colour.

    Thanks
     
  3. I'd try cutting it first
     
  4. Hi, what do you guys use to clean out the gun after using 2k? Most 'gun wash thinners' seem to be celly based, will that work? Using 2k thinners seems an expensive way of doing it.

    Cheers.

    Thinners is thinners. You could even paint with gun wash if you were a complete arse like someone I used to know. :)
     
  6. Cheers Zed, shows how much I know! I try to do paint as little as possible, just farm it out up the road but when I need to touch in a repair at the bottom of a wing... I just like to keep my tools in good condition by using the right thing to clean them.

    Likewise, I avoid painting whenever possible. :)
     
  8. @zed - before you get to the stage if painting, what grades of sand paper do you use to get the shape of the filler blocked back?

    Use 80 grit and finish/feather in to the surrounding area with 180. If you've alot of filler to rub off use 40 grit, to take out the bulk, but be wary of using 40 as you'll have to rub out any deep scratches it'll leave in the area surrounding the repair before priming.
     
  10. I was looking at 180g sanding sheets off eBay for a long block sander as need to fill sand the long sides :(

    Get some 80's aswell, you'll be there all week using only 180's!

    What Kruger says. Even 120 grit and you'll be there forever. The coarser the paper the less hard you'll need to press to get anywhere which is essential with the give in the big flat panels. MUCH easier to get the shape with coarse paper.

  13. If your using a long block , or long bit of wood the longer the better to get the side lovely and straight. then rolls of paper are better. toolstation do them and good price
     
  14. This thread is 3 years old today! Hapy Birthday.
     
  15. I've got a 70x400mm sanding block with some fresh sheets on its way to me. Been using a DA to get the majority sanded once filled then will use the block to get the shape. The DA has only been used between layers so far to smooth off before the next one lol

    You have to be pretty skilled to get a good shape with a DA, they tend to follow the undulations.

  17. hello,

    I'm not far off coating sprout in primer ready for his new colours. Does anyone have a rough idea of how much cellulose is needed to paint a bus?? it's a double cab so not quite as much as it would take to do a tin top but not by much...

    i'm doing a two tone so was thinking of 3 litres for the top, loadbed and inside the dropsides and 3 litres for the bottom half and inside of the cab. (thats before thinners) does this sound like too little??
     
  18. as it turns out, 6litres is about right for a 3 coats :)
