Please confirm cut lap and resin tint technique!

ok,

 sifted through archives and other posts and just want to confirm my procedure for resin tinting the bottom of my 'lis fish' creation!

- tape up cut lap on deck

- flip board and glass bottom with resin tinted lam (maybe red, maybe yellow or maybe a combo to get a swirl!)

- once gelled, flip board and cut away excess cloth along tape edge

- tape up cut edge along the coloured side of the original cut lap, and glass with clear lam up to tape edge (creating a 'join' where the coloured lap edge and deck glass meet

- glass a second layer on deck in clear lam, wrapping around rails

- hot coat

- add pinlines

Questions I have are;

1.If the second layer of cloth on the deck is done as a free lap, will this show up on the coloured bottom side or can it be sanded flat before hotcoating to hide it in similar fashion to if it was all done clear?...OR should this second deck layer be also done as a cut lap?

2. Should both deck layers (clear) wrap the rails as per normal clear laminating for strength?

Pretty keen to get this 'fairly' right, any tips would be handy!

Hope it makes sense!

I have a post from KENSURF from one of the archives 'show us your resin tints and patterns' which is what I think I wil follow;

this is my proceedure... ( I do clear decks and colored bottoms thats why I call yours reversed)

tape off deck or bottom
flip board
do color work and wrap rails to tape line,, let gell good
flip and trim
tape off color line
Lam one layer of glass let gell good and trim
sand the lap line smooth and
lam one more layer over the clear side wraping around the rails
proceed to ot coat
pinline if the cut line looks like shit ( mine usualy do but dont tell Vader)

Cheers guys

first ,,, thank you for choosing my teqnique, Im honored

 1st ,,,, free laps usualy are not noticed if done cleanly

to answer your 2nd question

another way is

after the deck lap is cut and the lam is hard

push the edge of the lap into the foam

then do two full layers of glass wraping the rails

yes it will be stronger and heavier

…hello,

if you cut the cloth and not wrap the rail you ll end with a weaker glass work

plus, if you for some reason finish with a not so good sanding process, you ll have kind of a separated sections; one with cloth on the deck and then other with cloth on the rails

If doing deck clear, both layers of cloth should wrap, bottom layer about to rail apex, second layer around rail to flats on bottom.  No need for cut lap, use styrene if necessary.

Hi guys

Was just wondering if you are doing just colour work on the deck, do you do this first then the clear lam on the bottom after?

So the process would be

Tape off the bottom for cutlap

Lam the 2 layers of cloth on the deck in desired colours

Cut the decklap and tidy up

The single layer cloth clear lam on the bottom (free or cut lap)

Looking to create this sort of look. Tinted on the top and clear on the bottom

Does this process seem right?

Hi -

You might find it harder to do a clean tint and then cut through double laps with a double layer deck lam. Try laminating a single colored deck layer first. Spend some extra time to get the laps smooth and even.  Cut lap and knock down any rough edges with a file or surform - don’t go too deep on the clean up or you’ll mess up the tint. Then laminate single layer bottom and freelap to the deck. Clean that up after it hardens and then do a single clear deck with freelap to the bottom.
